Remote control of light via radio channel: types, connection diagrams, overview of solutions with photo examples and video instructions

Let's say you needed to install a new lamp somewhere, in a place where there is no special wiring for it, and this happens quite often. In such cases, it is enough to connect this lamp to the nearest outlet and install a compact remote control unit connected to the remote control. After which you will be able to use the lamp, controlling its operation with this same remote control.

In addition, using a remote light control system, you can divide existing lighting groups into several, change operating modes of lighting fixtures and much more.

For greater clarity and confirmation of my words, let's look at the process of installing a remote light control system from a remote control in an ordinary apartment .

I will try to describe the installation of light control from the remote control in as much detail as possible, point by point, with connection diagrams, so that you can use this instruction as a step-by-step installation guide.

Popular manufacturers

There are several modifications of contactless sockets and switches on the Russian market. It is advisable to consider products from popular brands.

Feron

Remote switch Feron TM75 23344

The following models are relevant in apartments and private houses:

• TM-75. Plastic switch with adjustable start delay for a 220 V network. Equipped with 20 channels. Included is a remote control.
• TM72. A remote control is used for control; devices are connected to 2 channels with a capacity of up to 1 kW for different light sources. Operation delay – 10-60 seconds.

Both devices have a coverage range of 30 m.

Inted

Several devices are produced:

• 220V. Single-key player with wall mounting (screws or double-sided tape) with a voltage of 20 V. Operating range - 50 m, amplified by a signal receiving unit. The case is plastic.
• 1-CH. Designed for lamps up to 900 W, controls light and alarm. It is made in the form of a key fob that transmits a signal over 100 m. It quickly fails in damp rooms.

The Inted 220V series also includes a model for two receivers with two channels.

BAS

Series of smart switches from BAS-IP

The inductive switch IP SH-74 has two independent channels. Controlled from a smartphone via a branded application. Compatible with incandescent bulbs up to 500 W and fluorescent lamps 200 W.

Z-Wave

8 devices are connected to the radio-controlled gadget. Power comes from two batteries. The maximum operating range is 75 m. The housing is moisture-resistant, with IP30 protection.

Nootechnics

Wireless switch NooLite

The Belarusian brand Nootekhnika nooLite has a line of products with programmable modes. They are activated using a multi-channel RGB controller. There is a dimmer to adjust the light.

The infrared model Sapphire-2503 is available with a dimmer, but is not suitable for energy-saving lamps. The lighting turns off some time after the user leaves the room. Load limit – from 40 to 400 W.

All devices are compact and easy to install.

Important Features to Select

Before choosing a remote switch, you should decide on the number of groups of lamps served by the device; you can select from 1 to 8 channels.

Low power consumption of push-button and touch radio switches in standby mode 10% - 30% ensures long-term operation of the transmitter without replacing the battery for 2-7 years.

You also need to sum up the connected power of the light sources and select a product with the optimal value of switched load power in the range of 0.2–5.0 kW. It should be taken into account that “remote transmitters” using IR rays operate within the line of sight of the receiver, and radio waves are able to bend around obstacles and penetrate through walls and ceilings in a building. You should not “chase” a transmitter with a maximum permissible radiated power of 10 mW and a coverage area of ​​100 m, since in a private house a range of 25–30 m is sufficient.

Correct connection

In order to properly mount the switch, you need to know its operating principle, what the device consists of, and how to connect the Wi-fi switch. The connection diagram for this wireless device is very simple.

One of the advantages of a Wi-Fi light switch is its ease of use and connection. If you really want to, you can install the device yourself

It is important to strictly follow the instructions provided by the manufacturer. This installation takes only a few minutes

The connection process consists of only two stages:

1. Installing a radio receiver.
2. Installation of a light switch (control button).

Basically, receivers have from two to four wires. They come out of the device body. To determine the input wire, you must read the instructions. The remaining wires will be output wires, for example, a double switch will have two outputs. To install the receiver, you must open the phase that supplies power to the lighting device and connect it to the circuit, while observing the sequence.

In the case where it is necessary to connect more than one lighting group, proceed as follows:

• zero is supplied to all lighting fixtures;
• the phase is branched in the Wi-fi switch;
• the phase should be supplied separately to each group of lamps.

The control button is installed quite simply; first you need to make a hole in the wall using a hammer drill with a concrete cutter. A regular plastic socket box is inserted into the finished hole, and plaster can be used to secure it. The installation process is absolutely no different from installing a key-type light switch. The only difference is that there is no need to lay wires, you just need to securely fasten the button in the socket.

Finally, we recommend watching a video that clearly shows how to connect a Wi-fi light switch:

Now you know what a Wi-fi light switch is and how lighting is controlled via a smartphone. Wireless electrical accessories are becoming increasingly popular, so if you decide to implement a Smart Home system, we advise you to acquire the devices we have reviewed.

It will be useful to read:

• How does a Wi-Fi socket work?
• Remote lighting control systems
• Heated floor control systems

Self-connection

You can consider the features of connecting a contactless limit switch using the example of Zamel RZB-04. It is equipped with a two-channel receiver, a two-channel switch with 4 modes, and mounting brackets. The device has 5 operating modes:

• Inclusion. After the button is pressed in any position, the lamps light up or go out.
• Shutdown. Occurs when a key is pressed.
• Monostability. Operates in pressed button mode. After releasing it, the light will go out.
• Bistability. To turn on/off the light, successive pressings are used.
• Temporary mode. The pressed button starts the device for a short period.

Connection instructions

The connection diagram depends on the number of channels. Single-channel ones are connected by breaking the phase cable connected to the luminaire and throwing the core onto the Lin and Lout terminals. Multichannels are installed like this:

1. The power supply is turned off and the voltage is checked with an indicator screwdriver.
2. The old switch mechanism is removed.
3. Voltage is supplied, but only the phase is sent to the switch. It must be permanent, for which it is connected to one of the conductors with terminal blocks.
4. The phase is thrown onto contact L without passing the wire through the devices.
5. Zero is supplied to contact N using a wire from the distribution panel.

At the final stage, the switch is connected and electricity is supplied.

Configuration and reprogramming technology

First you need to select the operating mode of the system. By default, this is the standard functionality with the wireless switching up to turn on and down to turn off. To reprogram:

1. Using a screwdriver, press the PROG button of device No. 2 and hold it until the red light comes on.
2. Duplicate the action on the top of the radio switch button. Wait until the red light comes on.
3. Press the lower part until the diode activates.

The remaining actions are performed according to a similar algorithm with the second key.

Switch Installation

The delivery set includes double-sided tape or dowels with self-tapping screws. When working with adhesive tape, the use of tools is eliminated and it is easier to adjust the position of the device. The tape is cut into 4 pieces, which are glued to the device.

After installation, a test lamp is installed and the system is checked. You need to move the button to the top and then to the bottom position. The start is indicated by a light indicator.

The installation location can be cabinet doors, a safe, or a gypsum plasterboard partition. The switch on the door can be installed at the level of a child's outstretched arm. The headboard, wall and floor will create additional comfort of use.

Infrared and radio wave control of light from the remote control

Infrared lighting control using a remote control is used extremely rarely. Basically, such systems operate on the principle of transmitting a signal over a radio channel. To be able to manipulate lighting devices using an IR beam, a remote lighting control unit, for example BM8049M, is connected to the open circuit. It allows you to turn on the lamp switch using a regular TV remote control. To do this, point the remote control at the unit, press any key (which is not used to switch channels), after which the command is recorded in memory and now you can control the switching on of the light without getting up from the couch.

The main disadvantages of using IR remote control lights are the need to accurately point them at the signal receiver, since they only work within line of sight, and the short range of the beam, but in this case repeaters can be used.

Light control systems using a remote control have become much more widespread, in which a signal is transmitted from a control device to a controller that regulates the process of turning on/off the light at a certain radio frequency.

Light control via radio is more in demand for several reasons:

• The ability to control the light not only from the remote control, but also from a computer, smartphone and other devices;
• The signal range is about 100 meters in the absence of obstacles, 15-25 meters in the presence of obstacles;
• Possibility of installing signal amplifiers and repeaters for better transmission of commands from the control device.

The lighting remote control system via radio using a remote control consists of:

• Remote control;
• Battery;
• Remote control controller connected to the network and load.

Install the controller into the wall or glass of the chandelier (see photo). It can control incandescent lamps, compact and conventional fluorescent, halogen, and LED lamps, and not only individual lamps, but also a group of them.

Receiver switch

The device is a touch or push-button light switch, additionally equipped with a radio signal receiver. Here we are talking about high-quality lighting control: mechanical on/off and control from the remote control do not depend on each other. Similar switches are found in some electronics manufacturers; in general, this is a rather rare solution implemented by any brand.

The range of such devices is small, let’s look at them briefly.

Among simple devices, we can note, for example, Wookee wk-317e - load control up to 500 W, remote control range (according to the seller) 30 meters. The radio frequency of 433.92 MHz is standard for most radio light control devices. The switch is quite bulky and requires a non-standard installation box (socket box). The kit includes a control panel, which apparently cannot be replaced with another device. Unfortunately, there is no information on whether the switch requires a neutral conductor.

Receiver switches from Legrand Celiane series have more advanced options - they can be controlled not only from the remote control. The device has the function of a full-fledged radio relay and can work with various transmitters - remote controls in the form of a regular switch, motion sensors and Internet signal translators. Naturally, all these devices are supplied by the same manufacturer. Some receiver models support dimming. Among the disadvantages, it should be noted that this device is quite difficult to find, and also that the receiver switch requires a neutral wire. The presence of a zero can become a serious obstacle when installing in an already equipped place for a regular switch (after all, a zero is not provided).

During the search process, I managed to find the best solution, in my opinion - a switch from Aliexpress Smart Switch. The switch is mounted instead of the usual one, a neutral conductor is not required! The touch switch is produced in various colors and can have up to three independent control groups. A four-button compact remote control or other device (like Legrand) is purchased for the device. It is worth especially noting that the four buttons on the remote control can control many light groups and several switches; the switch itself is easily programmed to the desired key. There will be a short review about this model soon. The device does not switch on during power outages.

In addition to the Legrand and the “unnamed” Chinese device, there are other manufacturers, for example Brenin Mount Switch. This device can also be used as part of a smart home - with a remote control, various sensors and switches. However, I was unable to get competent technical advice on their supposedly official website. There are suspicions that they do not have a dealer in Russia, and that the site was created by some charlatans.

But on the noolite “Nootekhnika” website it is quite possible to get advice from a competent specialist. But, unfortunately, they do not have a ready-made solution in the form of a switch-receiver. However, there is an SB-1-100 block - it is connected to the lighting circuit break (zero is not needed), like the devices described above, and is also connected to any push-button or conventional type switch. The block itself is mounted in the mounting box under the switch itself. The unit is compatible with all noolite smart home devices - remote controls, sensors and wireless switches. Capable of operating in two modes (selected during installation): relay, when the switch is only on. or off and dimmable, when the brightness of the lamps is smoothly adjusted.

All described devices consume a miniscule current from the circuit even when the lights are off. Therefore, when using energy-saving or LED lamps, chandeliers and lamps must be bypassed with a 0.1 - 0.2 µF capacitor. Otherwise, the lamps may glow dimly or flicker. Read more about glowing and blinking LED lamps

Typically, a bypass capacitor is supplied with the receiver switch.

Using the devices described above, a light control circuit based on the principle of pass-through switches is very simply implemented. The receiver switch is connected instead of a standard switch, and the remaining control points are implemented using remote switches (transmitters). The disadvantage of such a system is that additional control points (transmitters) require batteries. Well, an undeniable advantage is that there is no need to run wiring to the transmitters.

Remote lighting switches. Installation of walk-through wall switches without wires.

There is, and it’s absolutely inexpensive. All costs can cost you between 500-1000 rubles. At the same time, you won’t spend a penny on new wires and won’t cut through a single extra centimeter of the walls.

In fact, you are buying a ready-made solution and installation costs are minimal. They come in single-key, two- and three-key types.

The switches themselves can be mounted on the wall in two ways:

• on the double-sided tape that comes with the kit, directly on top of the wallpaper or tiles

• for self-tapping screws into an existing socket box

The most important component of the remote switch is the power radio module. It is no larger than a matchbox.

Thanks to this, you can place it anywhere - in junction boxes, behind a chandelier cap where the wires are connected, behind a suspended ceiling, etc.

You can also install it inside the old one, taking out all the “gibles” from there.

But most often they are installed in the chandelier cap, since there is plenty of space there.

A voltage of 220 Volts is supplied to the radio module and transmitted to the lamps through its contacts and relays.

You can easily attach several switches to one module - one, two, three, four, it doesn’t matter.

To create such a circuit using simple pass-through switches, you will have to pull a bunch of extra wires, and also buy another type - changeover or crossover. Read more about this in the article – “Pass-through switches. Connection diagram.”

You can also attach a remote control or key fob to the device. And then, to control the lighting in the house, you won’t even need to go to the switches and press them.

You can lie quietly on the bed, put the keychain on the nightstand and turn off the light without getting out of bed.

Since the power of street lamps is many times greater than that of indoor light bulbs.

The switch is very easy to disassemble. It is enough to use a screwdriver to pry out the slots at the junction of the cover and the body. There is no need to unscrew any screws.

Area of ​​application of the devices

The scope of use of wireless devices is very wide. Models are installed in apartments where there is a need to install a changeover switch or to move an old traditional switch, but this is hampered by the structural features of the room, household appliances and furniture.

In case of urgent need, a wireless switch can be installed not only on the wall, but also on a mirror or inside one of the cabinet shelves. Regardless of its location, the module will function efficiently and provide comfortable control of lighting fixtures

To correct the errors of incorrectly made wiring, you no longer need to dismantle the external decoration of the walls and punch new grooved channels. The problem will be instantly solved by installing a wireless switch. It can be placed in any convenient place, forever forgetting about the difficulties associated with the home lighting system.

Installing a wireless device is the least labor-intensive and cheapest way to ensure comfortable control of the lighting system. The switch can be installed even in rooms with high humidity and sudden temperature changes

Lack of free space in a living space is another reason for installing a wireless module. The device can be placed in a minimal area and even built into any piece of furniture.

For wooden buildings, where electrical wiring equipment is associated with increased security measures, wireless elements are more than relevant. Of course, you can organize external wiring, however, this does not always match the interior and often spoils the attractiveness of the room.

In addition, exposed electrical wires are vulnerable to mechanical damage from residents, children and animals. To protect yourself and your home, it is wiser to install wireless modules and no longer worry about a force majeure situation (fire, short circuit, etc.) resulting from wire damage.

Organizing hidden wiring in a wooden building is problematic and unsafe. An overhead wireless switch will be a lifesaver for owners here. You don't need to call an electrician to install it. The work is simple and even an inexperienced home craftsman can handle it.

If the room is divided into locations, each of which requires its own type of lighting, it is not at all necessary to do a huge amount of work and run wiring to all the switches.

It is enough to simply install a wireless device that can control several light sources and use the remote control to turn on or off the lighting fixtures as needed.

When all repair work in a room has been completely completed and the walls are decorated with a finishing coating (wallpaper, fabric, paint, tiles, laminate, etc.), but there is an urgent need to install another switch, there is no point in dismantling the finishing and punching additional groove channels.

It is better to install a practical wireless device. This will take a minimum of time, and the appearance of the room will not be affected in any way.

To control the lighting system in large cottages, conference rooms, long corridors and other large spaces, wireless modules are simply created. They allow you to turn on the light while being at a great distance from the room or even from the street.

If the building has historical value (antique houses, museums, etc.) and making changes to the interior solutions is considered unacceptable, it is worth using wireless switches. They will provide full control of the lighting system and will easily “hide” in pieces of furniture, without giving away their presence and belonging to modern life.

Increasing the comfort of your home is an excellent reason to install a wireless system. It will allow owners to control the lighting of rooms and utility rooms, literally, with one click of a button and adjust the light intensity according to personal needs and preferences.

Imagine: you drive up to your house, open the gate, and the lights in the garage and on the driveway immediately turn on, as well as the lamps along the path leading to the house, and the house lamp - now you no longer have to make your way to the switches in the dark. Or another example: you climbed under a warm fluffy blanket in bed and decided to read a book, and you’re too lazy to get up and turn off the ceiling lighting; you can use a special remote control to turn off the excess light and leave only the bedside sconce. All these small but important advantages of the development of technical civilization are provided by remote control of lighting. In this article, we will tell you what lighting control systems there are, what devices can be used for this, and what types of signals.

Lighting control systems

Lighting control can be organized in various ways. This can be control of all lighting fixtures in a house or apartment from one controller installed in a convenient location, or from one remote control that allows you to turn lamps on and off in different rooms, and it is also possible to control lighting automatically according to a pre-defined scenario or trigger the corresponding sensor. Most of the functions related to lighting control can be performed by the smart home system. It is capable of combining all the systems that will be listed below.

Centralized lighting control

In very large houses and industrial enterprises, for convenience, group panels are installed for centralized lighting control. For example, if the building of a bathhouse, guardhouse or barn is no longer needed, the lighting in them can be turned off from the main building from the central control panel. In this case, control can be carried out directly in hardware on a common panel, or perhaps on a separate special controller.

In an ordinary apartment, a common controller is sometimes installed near the front door. When you're in a hurry getting ready for work, turning the lights on and off behind you is sometimes simply inconvenient, because you're rushing here and there. And so, when leaving the house, you can press a button and turn off the lighting in the entire apartment at once.

The most convenient and advanced is centralized control from a computer or even from a mobile device in any part of the world. But this is already a remote control option.

Remote lighting control

Lighting can be controlled from a distance in a variety of ways. The most common and accessible one is the lighting remote control , which looks very much like a regular TV remote control. Most often it has from 4 to 7 buttons, each can control one group of devices. Each group can have from 1 to 262 devices.

Using the remote control, you can not only turn on and off lighting fixtures in a particular room, but also adjust their brightness. For example, while lying in bed, you can turn off the overhead lighting and leave only the bedside sconce, or in the living room, dim the general light for a romantic dinner.

Using remote control of lighting in an apartment does not always make sense, since the need to turn on or off a particular lamp is in one way or another connected with moving around the apartment. For example, supporters of remote control always give an example of how convenient it is to turn off the light in the kitchen from the bedroom, which you forgot to turn off when leaving it. You might as well forget the remote control in the kitchen. And if several people live in an apartment, should everyone have their own remote control? How to determine who will turn off the light forgotten in the corridor? Or another example: remotely turning on the lights in the toilet and bathroom, how necessary is it? In any case, the light in the toilet may be needed only for the specific purpose of visiting it, what prevents you from flipping the switch when entering? Well, if you’re really lazy, then you can install motion sensors - the lights will turn on when someone enters the room, and turn off when they leave.

The only more or less meaningful indication for using remote lighting control in an apartment is multi-tiered lighting, when ceiling lamps, a central chandelier, wall lamps, sconces, and also decorative lamps in niches are installed. In general, when you see a miracle of design thought. Then actually turning off some of the lighting in the room without getting up from the couch is convenient and advisable.

But the most justified is remote control of outdoor lighting . The height of functionality is to regulate the lighting of the local area, technical buildings and alleys from one remote control, without leaving the house. It is also very convenient to control decorative elements: lighting of flower beds, fountains, ponds and green areas from the smart home controller.

In addition to a large, full-fledged control panel, you can use a small remote control - a key fob with a limited number of functions. For example, just to open the gate and turn on the light near the front door of the house or in the garage.

Controlling the lighting from a computer located in the same house is very convenient if there is no remote control nearby. Typical software solutions for a smart home system can be installed on a computer and be able to fully regulate all lighting groups and devices.

Lighting control from a computer anywhere in the world is carried out in this way: using a special program and password identification, you need to log directly into the home control device or intermediate server and turn on or off the lighting fixtures in a particular room. This is very convenient if you forget to turn off the light, or to create the effect of presence.

Lighting control using a smartphone is provided using a special client software application. In many ways, this control is similar to the previous method, only from a less functional device.

It is even possible to control it from a regular cell phone by sending encrypted SMS, this is called GSM control.

The easiest way to remotely control lighting is a wall controller . When the last occupant of the home leaves the house, he can press a button and turn off the lights in all rooms. And when he comes home, the light turns on only in the hallway or corridor.

Automatic lighting control

Using automation such as motion sensors, photocells and timers to control lighting is very convenient. For example, you can install motion sensors and no longer bother wondering if I forgot to turn off the light in the toilet. According to the given program, a minute after they left it, the light will turn off by itself. The use of motion sensors is convenient if there are small children in the house who simply cannot reach the switches. And so the light will accompany them everywhere.

Photocells allow you to adjust the intensity of artificial lighting depending on the general illumination. For example, with the onset of deep twilight, the lighting near the front door of the house and the illumination of alleys and paths are turned on. And with dawn, all artificial lighting turns off on its own.

Lighting control using a timer is used in cases where the lights need to be turned on and off by the clock. For example, 5 minutes before the owner arrives from work, if he has a normal schedule. Or turning off lighting and outdoor advertising during dead time, from 02:00 at night to 05:00 in the morning.

Lighting control devices

Various devices and devices are used to control lighting. Some of them are direct controls, others are auxiliary sensors or devices, receiving information from which the former are triggered.

Lighting control unit

Used to remotely control a group of luminaires. Connects to lighting fixtures of a specific group. When you press the button, it turns the devices on or off forcibly.

There are also blocks that allow you to control a lighting group using a regular remote control from a TV or other equipment. The buttons on the remote control can be selected arbitrarily and then programmed for specific actions. The block allows you not only to turn the light on and off, but also to adjust the brightness, as well as turn off the light using a timer.

Lighting Controller

The controller is a functionally complete automatic machine, capable of controlling lighting in automatic mode according to a given program, in remote mode from the remote control or according to information received from sensors, as well as in manual mode using buttons. Programming of the controllers is carried out using the built-in keyboard and LCD display.

The lighting control circuit using the controller is shown in the figure.

Lighting control sensors

Motion sensors are installed in rooms where automatic light control is planned depending on the presence of people in it. Pyrosensors of the sensors detect thermal radiation from people and animals, send a signal to the control device, which turns on the light or turns it off if the room is left. The operating principle of motion sensors is based on IR radiation (infrared), which does not pass through natural barriers such as walls. If there is someone in the next room, the sensor will not trigger.

Light sensors capture the luminous flux of natural light. If the intensity decreases to a predetermined threshold, the sensor transmits a signal to the control device, which turns on the lighting, for example, in the evening or cloudy times. Such sensors are mainly used only for automatic control of external lighting of alleys, technical lighting of buildings, terraces, etc.

Remote controlled switches

Like modern televisions, stereo systems, DVD players and other devices controlled using infrared rays, the first to appear were switches, sockets and dimmers that respond to infrared rays. Control occurs using an infrared remote control, which must be pointed clearly at the IR receiver on the switch. In this regard, control is possible only within line of sight, but not in other rooms.

Radio-controlled switches allow you to control lighting in different rooms and beyond at a distance of up to 100 m through any obstacles that reduce the signal level, but do not block it completely. The frequencies used for radio control of lighting, 433 MHz and 868 MHz, are specifically designed for this purpose, so that air pollution does not occur. Sometimes special adapters are produced that convert IR radiation into radio frequency.

GSM controlled switches allow you to control lighting from your phone remotely. Using a special program installed on your phone or smartphone, you can turn off or turn on the lights in the house, no matter where you are.

Lighting control panel

For remote control of lighting, both IR and radio-controlled remote controls are used. In some cases, you can use a regular TV remote control by reprogramming it accordingly.

Radio-controlled remote controls are now in demand, as they have sufficient functionality. They can have up to 7 - 9 buttons that can control different lighting groups. Each group has its own address. When you press the button, the signal goes out to all groups at once, but only the group whose address matches is responded.

Smart home systems use remote controls that allow you to regulate and control not only lighting, but also all appliances and electronics in the house.

Photocells

Photocells must be installed in places where there will be no illumination from lamps, so that false alarms do not occur. The device does not respond to temporary flashes, such as lightning or car headlights, only to the general level of illumination.

Timers or time relays

A time relay is used when it is necessary to control lighting according to a specific schedule. For example, outdoor advertising lighting needs to be turned on at a certain time and turned off too. Turn off the street lighting of the garden or local area at night and turn it back on before dawn. The built-in processor itself determines the time of sunrise and sunset and calculates the required time.

All these devices and appliances are designed to simplify our lives and make it even more comfortable. The simplest remote lighting control systems do not require replacement of wiring or additional wires; it is enough to replace switches or install special units in chandeliers. But for more serious control using the smart home system, you will have to form a serious network connecting all devices.

Remote control of light using infrared and radio switches

Infrared switches are a rarity in the lighting market, as it is smarter to control the light using radio devices. One of the most popular switches is “Sapphire” from Nootekhnika (Belarus). The same company produces many wireless lighting control devices, including those mentioned below. The switch is controlled by any remote control, for example, a television remote control or manually. The signals are received by a receiver located inside the device on the touch panel. The light switch with remote control is shown in the photo.

Radio switches allow you to control lighting manually and from a remote control (you need to link it), and in appearance they are not much different from standard “circuit breakers”. Their interaction with the lamp occurs through power units connected to a 220 volt network and load (see connection diagram). You can connect 220-volt incandescent and halogen lamps, halogen lamps via an electronic or ferromagnetic transformer, as well as fluorescent and compact fluorescent lamps to the power units.

A remote-controlled light switch is placed in any convenient place, power units are placed in a distribution box or chandelier glass.

Varieties

Wireless switches are classified according to three main characteristics:

1. Lighting control method. Devices offered in trade today are equipped with push-button or touch switches and remote controls.
2. Possibility of smooth adjustment of the light flow. The lighting intensity is changed by long pressing a special button on the device with a built-in dimmer.
3. Number of controllable lighting fixtures. There are wireless DVs designed for 1-2-3 or more groups of lamps with different numbers of lamps.

Using additional options allows you to configure the command execution delay function for several seconds. It allows, for example, the user to perform a series of actions with the lights on until the room is plunged into complete darkness.

With remote control

Along with built-in switches, remote control of individual lighting devices or large groups of lamps can be carried out using a push-button key fob or remote control.
There are two buttons on the remote control for each channel. One turns on the power supply and increases the brightness of the glow, the other reduces the light intensity or turns off electrical appliances. The load is turned on/off by briefly pressing the button for 0.1–1 s, and the luminous flux is adjusted by holding the same button for more than 1 second. Screws for wall mounting of the accessory are included in the factory package.

Multi-channel radio switch

In a multi-channel radio switch, it is possible to configure up to 8 channels connected to the lighting system. This allows you to control the lighting in the entire apartment or rooms in the house.

To avoid confusion, radio switches remember the addresses of exclusively “native” remote controls and execute only commands of their bitrate.

It is set by a certain speed of transmission and reception of information, measured in kbit/s, while the frequency of the transmitted signal of 30-40 kHz remains unchanged. The basis of each remote control is a pulse generator, the signal of which is modulated by the code of a specific command. An incomplete remote control can be untied and linked to the device if its unique number matches the same switch code.

Touch panels

Externally, the touch panel is a crystal glass screen with applied markings, visualized by backlighting. By briefly applying your finger, switching is carried out, and by holding it in the designated place on the panel, the illumination is adjusted with a dimmer. The human capacitance introduced by contact changes the parameters of the capacitor in the electrostatic field, a control signal is generated, from which the switch switching circuit is launched. The absence of mechanical keys in the design increases the service life of wireless DVs to 100 thousand activations.

Wi-Fi or RF

The presence of a Wi-Fi extension in a smartphone, tablet or computer with Internet access allows you to control the lighting using the gadget in a similar way to a remote control. When you send a certain command from the gadget after clicking on the device icon and the corresponding action icon in it, the transmitter generates a pulse. It is then converted into a 2.4 GHz or 5 GHz radio frequency signal from the Wi-Fi router, which is picked up by the device's receiver within the router's coverage area.

Advantages and disadvantages of remote control devices

Devices that allow you to control lighting using a remote control have certain pros and cons. The most important advantage is the ease of installation and ease of connection: installation of the device does not require special knowledge.

The ease of use and the ability to smoothly adjust the lighting fixtures attract attention. Some models also have a device programming function, with which you can set the “presence effect”

In this case, the device will turn on/off automatically at a certain time, which can be useful if the apartment is empty.

As a rule, manufacturers produce a set of equipment necessary to enable remote adjustment of lighting fixtures. The power unit must be connected to an existing electrical network

The use of remote control devices helps reduce electricity consumption, as well as extend the service life of various types of lamps. In addition, the remote switch makes it possible to simultaneously control several light sources or even other devices from one remote control.

The disadvantages of such devices include the occasional false or spontaneous operation; a weak radio signal that may not pass through an obstacle; possible effects on pacemakers or hearing aids.

Switches located outdoors may not operate correctly due to precipitation. In addition, the batteries on the control panel may run out at the most inopportune moment.

How the remote control works

Using the control panel, you can turn the light on/off and adjust the brightness.
Lighting controlled by a remote control is most often installed in offices and industrial buildings, but is becoming increasingly popular for residential premises. The most popular are control systems, which need to be controlled using a motion sensor connected to a radio wave switch. Mobile phones, computers and mini-controllers are also used for this purpose. To change lighting settings from anywhere in the territory by pressing the remote control buttons, devices capable of transmitting radio signals are installed in the electrical wiring. They activate the exchange of data packets with information that go from the central part of the system to the remote control device.

The package can include codes for various commands and can be programmed to suit the user's needs. In some cases, problems may arise due to too much distance, which can be solved by installing a repeat option in the remote control, transmitting data with the desired regularity and sequence several times. When choosing a device, you will need to take into account that each remote-type switch, after connecting to the general network, receives its own individual network address. For this reason, some signal transmitters can only respond to commands stored in the control memory.

The basic functionality of the remote control device includes the ability to turn lamps on and off at a distance, change modes and set settings. Users can turn off lighting devices partially in a specific segment of the room, which allows them to save energy and use light fluxes at their discretion. Modern systems provide the ability to remember and record settings, so the user does not have to constantly adjust the light; it is enough to program the remote control for several stages of lighting changes.

Most remote controls are equipped with sound and light alarms, allowing you to find them if lost.

Connecting remote switches

The installation diagram of such devices often depends on the light bulbs with which the device will work, as well as on other factors, so before starting assembly you should carefully study the instructions included with the model.

As a rule, products are designed for a standard voltage of 220 volts, however, with the specific requirements of the lamp, this figure may be underestimated.

When connecting any model of switch with a remote control, you must follow safety rules. Do not touch exposed wires without turning off the power

If the system includes a voltage-reducing device, the control unit must first be installed, and only then the transformer. When you press a button on the remote control, the power unit supplies power either directly to the light bulb or to a step-down transformer (depending on the light source). Most often, a similar scheme is used when lighting rooms with LEDs.

Depending on the model, the power unit may have one or more channels: the latter option allows you to simultaneously control several devices at once.

Experts recommend connecting the remote device through a traditional mechanical switch, which can be used if the remote-controlled device fails.

Selection of high voltage circuit breakers

Selecting high-voltage switches is a more responsible and painstaking matter; here you can’t install them on a DIN rail. Here are the main parameters influencing the choice of such devices:

1. Rated voltage and current;
2. Switch type;
3. Number of poles for switching;
4. Type of installation corresponding to operating conditions;
5. Protection speed and shutdown time;
6. The number of complete switching cycles, that is, to what extent it is designed for switching on and off;
7. Thermal stability current;
8. Short circuit current limit;
9. Turn-on time if there is a remote drive;
10. Gas or air pressure, pneumatic or gas drives.

It is also not recommended to give preference to Chinese manufacturers of this equipment when choosing, since they very often save on non-ferrous metals. Recently, domestic manufacturers have reached a fairly high level of manufacturing circuit breakers, both high-voltage and those designed for voltages not exceeding 1000 Volts.

All the most important aspects are covered; now the safety of the wiring, and therefore fire safety, will depend on how correctly a person chooses this device. Since the most common cause of fires is considered to be a wiring fire, which means the selected and chosen machine did not turn off in time.

Remote control system for light in an apartment

Light control scheme via the Internet

Light control in an apartment can be carried out by switches with a range of up to 100 m or less, depending on the area of ​​the room. If there are load-bearing walls or iron reinforcement in the walls along the signal path, there are radio signal repeaters that allow you to bypass obstacles and increase the power of the transmitting device.

You can install 2 light control systems in your apartment:

• Local, if one lighting source is connected to one switch.
• Global. In this case, all lamps and spot groups will be connected to a single control panel. The scheme may include air conditioners, ventilation systems and other electrical devices, for example, automatic blinds or roller shutters.

In large apartments it is possible to combine the operation of sensors and a remote switch. This is necessary for temporary lighting of passage areas. The sensor is installed in the direction of travel and is triggered if a person enters a certain area, then turns off.

The device can operate in several modes:

• Temporary. When you press the button, the light turns on for a certain time, then goes out on its own.
• On/Off. When the button is pressed once, the devices are either turned on or off.
• In monostable mode, holding down the button will keep the light on. If you let go, it will go out.
• Bistable mode is a cyclic change in the operating state of the device.

The more modes, the more expensive the equipment.

Features of remote control systems

Infrared IR devices

Household switches with remote control, operating using infrared radiation, are distinguished by the following design features:

• Remotely controlled switches are installed in a break in the line supplying the lighting circuits;
• As such devices, as a rule, standard modules such as BM8049M or similar circuits are used;
• To control their operation, ordinary remote controls for television receivers of certain brands can be used (this option must be indicated in the instructions for this device).

If it is necessary to turn on the lighting, the diode emitter of the control panel is first pointed at the receiving and switching unit, and then by pressing a specially dedicated button, a command is sent to memorize this function.

Upon receipt and decryption of the parcel, it is recorded in the memory of the actuator, after which the light can be turned on via an established communication channel directly from the remote control (see figure below).

Control block diagram from the remote control

Helpful note. The main disadvantage of systems with IR radiation is the need to very accurately point the remote control at the receiver, since these systems operate only within the line of sight.

Let's add to this the not very long range of the emitter, which in some cases can be increased by installing expensive repeaters.

Overview of remote switches

Among the most well-known models on the market, we especially highlight the IR remote light switch of the Sapphire-2503 type, produced in Belarus, as well as a system with a radio-controlled channel of the Nootekhnika Noolight brand. The product of the first of these companies can be seen in the photo below.

Remote control type "Sapphire-2503"

Another type of wireless switches and switching devices for lighting equipment over a radio channel is produced by the well-known. These include such common models as AWST-8800, AWST-8801, as well as the portable key fob “CoCo” AKCT-510 and the built-in transmitter AWMT-230.

Models from the last two manufacturers of remote control systems are more practical and convenient than similar switches with signal transmission via an IR channel. With their help, it is possible to simultaneously control all lighting equipment in the house from almost any point (from the most remote rooms). The presence of special dimmers in the set of these devices significantly expands the capabilities of the system and allows you to adjust the illumination of internal spaces.

The portable control panels included in their composition allow the possibility of choosing one or another scenario of actions leading to the connection of light. More “advanced” products from the considered manufacturers may contain a special RGB controller capable of performing a number of operations, namely:

• Turn on lighting at a given address or in the entire house at once;
• Adjust the brightness level of the lamps;
• In accordance with the given program, set the desired ratio of different color gamuts with LED backlighting and sort through them sequentially.

Due to the fairly compact size of the electronic part of these devices, the remote switch can be placed inside the glass of a chandelier or lamp. When controlled from a remote control, it can be switched over a radio channel from a distance of about 30 meters.

Most of the considered control system samples are capable of working with household consumers designed for power up to 3.5 kW. To connect them yourself, you must perform the following mandatory operations:

• First, a load with a suitable operating power for the device is selected;
• After this, the voltage from the house or apartment is removed automatically by the introductory machine;
• At the final stage of the work, a power unit responsible for turning off the light is installed into the break in the supply line.

All details of connecting the final execution device can be found in the next section.

Methods of automatic control of street lighting

The infrastructure of any settlement requires the presence of powerful lighting devices. Thanks to the time relay, they are able to turn off and start working at the right time.

Automated external lighting control system (ASUNO) "Energomera"

Automated operation of lamps is also used in the garden. This consumes significantly less power and adds a motion sensor to the relay.

Control cabinet

The control cabinet is the center in which all the circuits are collected, from where the load is distributed and full control over the lighting is carried out. Protection of photo relays of lamps from short circuits and voltage surges is also carried out through this control panel.

Operating diagram of the street lighting control cabinet: 1 - electric meter, 2 - lock, 3 - protection, 4 - cabinet. All information and indicators are transmitted via the Internet

Also, based on the service life, equipment is being updated here - the longer any cable or circuit operates, the greater the chance that the control cabinet will have to be de-energized and worn-out elements replaced for the safety of the site.

Option for assembling a street lighting control cabinet

The cabinet performs the main task: it controls the operation of the desired relay depending on the time of day, provides guidance using the remote control, and regulates the brightness of the lamps after the photo relay is activated.

What to connect?

These can be ordinary street lights with a simple relay, controlled from a remote control through a control box, tiny LED lamps along the paths, pendant lighting and a lamp above the front door. That is, any lighting fixture located outside the home, but falling within the coverage radius of the remote control.

Types of control

The following systems are considered traditional:

• magnetic or induction ballast - lights the lamp with an inrush of current, but power surges often occur, which is why you have to install an additional relay;
• electronic ballast – does not use a starter, there is no noise, no flickering, reduced energy consumption. It distorts the radio transmission, quickly disables the photo relay, the result is that it does not work depending on the time of day;
• option for enterprises - based on the calendar and daily time, controls lighting, starting from the “working/holiday/weekend” scheme.

The simplest and cheapest scheme for controlling street lighting using a photo relay, currently the cost of a photo relay is 300-400 rubles, you can connect all street lighting on the site to it

Street lighting control uses three types of devices:

1. A device based on a photo relay that turns the lamp on and off, based on the level of illumination on the street. In theory, a system using a photo relay responds perfectly to weather conditions, and on a cloudy day the device will operate earlier. But in practice there are too many third-party factors, including temperature changes and sensor contamination. Because of this, the operation of the photo relay occurs with errors.

   Control option using timers located in the control cabinet; experienced electricians will be able to connect the modules to the overall street lighting circuit and the automation will work according to the specified parameters both in winter and summer

2. Timer based system. It works perfectly regardless of the time of day: the machine turns on the lights in the morning and turns them off in the evening, all in accordance with the parameters specified by the program. But due to changes in daylight hours, the device needs frequent adjustments.
3. Astro timer. Created on the basis of the previous one, it is a controller interfaced with a watch. The operation scheme is simple: the controller contains a database of the location of the Sun over a given area, and based on this knowledge, the program sends a signal to the lighting control panel. The system requires minimal costs: every 2-3 years the power supply is changed and the time on the clock is adjusted. The error depends only on the degree of perfection of the program installed on the controller.

Control over area lighting

If finances allow you to stretch a separate cable to each lamp with a relay on the site, then one control cabinet will be installed inside the house, and another one at the gate. But such a shield must operate in parallel with the second one, which means that each unit will consume the energy of a full-fledged cable channel.

Using sensors to control lighting

Various motion sensors for remote control of lighting are widely represented on the lighting market. The most common of them are infrared. They are devices that close or open the lighting circuit when the level of infrared radiation increases in their “visibility” zone. As soon as a person or animal whose body temperature is higher than the background temperature enters the sensor’s field of action, the light turns on. As soon as a person leaves the sensor’s coverage area or remains in a stationary position for several seconds, the light turns off. Motion sensors are most often installed in entrances, above the front door, and less often - inside the apartment.

Operating principle and design

Receiver and Remote Switch

Structurally, the remote lighting switching device consists of a receiver and a signal transmitter.

More details about these devices:

1. Receiver. The element is made in the form of a radio relay controlled via a remote control. You can turn the light off and on from a mobile device connected to a Wi-Fi network, as well as from a wired switch. As a result of receiving a signal, the relay is activated and closes the contact elements or opens them. It is advisable to install the device in close proximity to the lighting fixture or inside it, if dimensions allow. In the case of spotlights, the device must be installed in the distribution panel or in the free space between the suspended and main ceilings.
2. Transmitter or remote control. The device structurally consists of a generator that generates electricity after activating a button on the remote control. Generation occurs after touching the sensor or transmitting signals from a mobile gadget. Electrically, the signal is converted into a radio pulse, which is picked up by the receiver. The transmitter can be installed in the wall or not installed at all, but carried with you. There is a power source inside the remote control, so there is no need to connect it to an electrical line.

Infrared control

Lighting devices are controlled by exposure to infrared radiation. To do this, the processor control module must be connected to the lighting circuit break. The action can be performed using the TV remote control. The device is pointed at the processor module, after which a button is pressed, which does not switch television channels. This leads to commands being written to the device’s memory, and then the lighting is controlled from the pressed key. The main disadvantage of this control method is the need to ensure line of sight at a short distance.

Radio wave control

This control option is more common. Signals are transmitted to the radio switch from the remote control to the processor module. which is tuned to operate in a specific frequency range. Packet data is exchanged using special codes. High reliability of signal transmission from the remote control to the radio switch itself is ensured by creating the required level of pulses and repeating them in a certain sequence. The signals are repeated several times. To prevent a situation where the lighting is triggered by a neighbor's remote control, each switch is assigned its own unique address.

Radio-controlled devices often use non-volatile controllers, which allows them to be used without connecting to a household network.

There is a button on the switch that can be used to turn off the remote control and switch the lighting manually. Such devices may be equipped with a search key, by clicking on which you can find a lost remote control. The device will report its location using sound signals. Lighting control is possible using a mobile device or computer. To do this, you must first download the program to the device and configure specific commands.

Radio-controlled switches are divided among themselves according to the power used, which can reach several kilowatts. It is possible to configure devices to work with individual lighting fixtures or entire lighting systems. The best option would be to control different groups of lamps from a common transmitter.

Mr. Borisych spoke about the principle of operation of wireless radio switches.

Outdoor lighting control systems

Late hours of the day for most owners of private houses are associated with the constant tradition of turning on outdoor lighting in the local area.

As a rule, a familiar switch in the house or an automatic one located in the electrical distribution panel is used for this. Automation of lighting in a personal plot allows you to turn on/off both individual lamps and their groups.

Such lighting control methods do not require significant financial costs and do not cause difficulties in mastering, which makes them popular among consumers.

However, these options for controlling street lighting are suitable only if there is an adjacent territory of limited size.

Large areas require control of outdoor lighting using more modern options that allow you to turn on the light with the touch of just one button.

The implementation of such street lighting systems is carried out through the use of radio-controlled or infrared switches.

Composition of the control system for home street lighting

The outdoor lighting control system operates wirelessly, and remote control of existing outdoor lighting is carried out through receivers and transmitters. Such devices are capable of controlling several electrical loads at once.

Modern lighting control systems support setting modular equipment to operate on a schedule, which opens up wide possibilities for programming such devices.

They also allow you to create light zones of various variations, organizing their work according to a predetermined scenario.

The issue of automating street lighting becomes most relevant at the end of the calendar year - it starts to get dark earlier and it becomes uncomfortable to return home in the dark.

The solutions on the market allow you to solve various problems of controlling outdoor lighting without human presence.

Connecting a photo relay will allow street lamps to be lit automatically as soon as natural light goes beyond the limits of comfortable perception.

This device is triggered by reducing the illumination to a predetermined level, after which the lighting is turned on.

Nero Electronics offers comprehensive solutions - automated control systems for outdoor lighting of the Intro II and Nero II lines. They use the following as actuators (receivers):

• Dimmers operating via a radio channel (Intro II line) are devices that regulate the illumination of luminaires with various types of lamps (8521 UPM, 8521-50).
• Relays of the Intro II line, operating via a radio channel, are devices for remotely turning on/off lamps with any type of lamps (8522 UPM).
• Smart dimmers of the Nero II line, working using PLC technology, are devices for regulating the light level of various types of lamps (8421 DIN, 8421 UPM, 8421-50, 8425-50).
• Intelligent relays of the Nero II line, supporting PLC technology, control luminaires with any type of lamp (8422 DIN, 8422 UPM).

The signal received by the receivers in the lighting control system from Nero Electronics is transmitted via remote controls of the Intro II and Nero II lines.

Types of automatic outdoor lighting system devices

Connection of lamps installed for security in local areas can be done using a motion sensor. As a rule, such models contain an infrared electronic sensor that responds to the presence or change in body position in the area where the device is triggered.

Among the devices used in the automatic control system of street lighting is an astronomical relay. Its distinctive feature is that there is no need for additional installation of a light sensor: the user just needs to enter his coordinates.

Installing a time relay will help to organize comfortable lighting in the local area, the functionality of which includes a shutdown delay. The device is controlled from a push-button switch.

The lighting in the yard turns off after a set time.

In some relay models, it is possible to set the settings for time periods responsible for turning off/on the lighting outside, as well as distributing them depending on the day of the week.

Street lighting control can produce beneficial effects when combining different types of equipment. Connecting motion sensors, as well as timers, will allow you to implement a scheme for automatically turning on two 20W light bulbs, followed by turning on two hundred-watt light bulbs after the approach of a person, causing the motion sensor to trigger.

The set of all devices that are used to control outdoor street lighting represents a single system that operates automatically or is controlled via a remote control.

Pros and cons

No need to chip walls

Devices that remotely control lighting have advantages and disadvantages. The advantages of their use include:

• ease of self-installation;
• no need for wall slitting or cable laying;
• convenient control of all lighting systems using a remote control or from a smartphone;
• large range of signal transmission and reception;
• no risk of electric shock;
• safety for children.

Among the disadvantages of wireless modules are their high cost compared to wired modifications, dependence on the stability of Wi-Fi, and the impossibility of using them with a low battery.

Connecting switches

There is nothing complicated about connecting remote switches. If you wish, you can easily install the device yourself. The receiver has two or four wires coming out of it, depending on how many groups of lights it controls.

One of the wires is the input, the others are the output. To install such a device, the master needs to break the phase that supplies power to the lighting device, and simply connect it in series to the circuit.

When a wireless device is installed, everything becomes even easier. There are no wires needed here at all, the master simply attaches the button to the box, and you’re done. As you can see, it's not all that complicated. To install remote switches, in-depth knowledge of electrical engineering is not required. You just need to know a little about the flow of current in a circuit.

Purpose of devices

Any household electrical switch is connected to a phase wire break. That is, a live conductor is connected to the input and output, but the neutral wire remains intact. If both wires are connected, a short circuit will occur in the electrical wiring. For indoor lighting, different designs of devices are used, the main purpose of which is considered to be:

• disconnection of the electrical network;
• supplying voltage to the lamp.

Typically, lighting is turned on and off manually by users. Indoor devices are structurally designed to operate in the electrical wiring of a house at nominal network parameters; they do not shut down under heavy loads and short circuits. Automatic switches installed at the entrance to the room are designed for this purpose. Their design includes:

• current releases;
• cut-off devices;
• arc extinguishing mechanisms.

Any light switches are produced for certain current and voltage parameters.
Structurally, they differ in the installation method, wire connection, degree of protection from dust and moisture, and control method. Most often, wires are connected to device terminals with screw terminals. Some latest models have spring terminal blocks, which allow for faster installation of electrical equipment.

Checking the functionality of the device

After the main installation is completed, it is necessary to ensure the correctness and quality of the actions performed. However, it is worth remembering that intermediate checks of the reliability of the fastenings, the correspondence of the color markings of the conductors, the absence of bends, fractures, and twists are recommended to be done at each stage of work.

The control check consists of a visual inspection of the installation site and then turning on the electricity. The absence of sparks, unpleasant odor and triggered machine and the presence of a bright, non-flashing light indicates strict compliance with all instructions.

With the help of these step-by-step photographs of the entire process of installing a switch, every person can independently repair or adjust the lighting system in the house. The main thing is to carefully follow the algorithm and remember safety precautions.

Controlling lighting from your phone

At first, touch control of light was used only in conjunction with the construction of a smart home, however, nowadays you can find a special photo relay in any room. Automatic lighting can make a person's life easier. A multi-channel switchboard is capable of turning on the lighting of all rooms from one point.

Experts highlight the following advantages of a remote lighting control system:

1. Control using radio waves can increase the security of the apartment. You can control the light from your phone, personal computer or using a timer. This will protect the apartment from intruders in the absence of the owners.
2. Great savings in necessary materials. To run cables to the switches you need a lot of expensive wire. It will also need to be replaced over time. The electronic control system needs a small amount of wire.
3. There is no dependence on the electrical power supply network. The multi-channel cabinet and circuit breakers are connected using radio waves, and all light control is carried out without connecting to a local network.

Such a control system is most convenient when it is necessary to control the lighting level in many places at the same time. It can be combined with a dimmer, which will provide the most comfortable lighting in the room.
