The main use of GSM sockets is to connect to them power sources of electricity consumption, such as air heaters, electric convectors, oil radiators, heat guns, infrared heaters, pumps, air conditioners and other similar equipment.
Taking this into account, an important point in the design of a GSM socket is the quality of the elements responsible for switching the load, namely the relay.
The most important characteristics of the relay are the number of operations (the so-called electrical and mechanical strength), the rated load that the relay allows to switch and, of course, the manufacturer. The relay used must be a special “power” series. Therefore, you need to pay attention to whether or not the socket manufacturer indicates what type of relay it uses in its products.
For example, the Telemetrics T4 GSM socket uses a relay of the professional “power” series JQX-115. Switched voltage and current - up to 250 V and 16A. The declared switching resistance is at least 100 thousand switching cycles. The relay has VDE and CQC certificates, which confirms the high performance of the device.
What is a Gsm socket with SMS remote control?
SMS or GSM socket is used for remote control of electrical appliances connected to the network. Such devices provide comfortable living conditions for humans. You can set a timer so that the electrical outlet turns itself off, or give a command to the device while outside the house. In addition to turning electronics on and off, the outlet can measure temperature and sound an alarm when the set mode has been reached.

Areas of application of smart sockets
For the dacha
At the dacha, a smart device can be used to water the plantings on the site according to a schedule. The user sets his schedule and the automation supplies water.
For home
At home, various power failures occur, which leads to accidents. From a distance you can control a heated floor, kettle, refrigerator, iron, boiler, oven and similar appliances.
For emergencies
If necessary, you can urgently de-energize any room. To do this, you need to set this function and all electricity will be turned off at once.
For offices
You can restart switches, network devices, routers, and servers according to a specific schedule. It is enough to set a specific operating schedule for the specified devices.
With temperature sensor
You can control the indoor microclimate using GSM sockets. The automation will turn heating and cooling devices on and off, working according to the sensor. Activation and deactivation of devices can be controlled manually or delayed using a precise timer. A smart socket with a thermometer and climate control function allows you to automatically turn devices on and off according to the ambient temperature.
It is convenient for the user that you can enter a special schedule, and according to it, the current supply will be turned on and off according to time. An SMS notification can be sent to your phone if there is an unexpected change in air temperature or power surges.
Security GSM socket
Smart plugs help protect premises from intruders. A sensor system protects against unauthorized entry into the home.
smart sockets are convenient to use at home and in the office; you can turn equipment on and off from a distance
What does the device consist of?
The device itself looks like an adapter. Inside the socket there is a board, sensors and a built-in GSM module, thanks to which control occurs. The electronic board is equipped with SIM card slots and a battery holder. There is a plug and a European socket on the case. There are also LED indicators and buttons, the number of which depends on the model used. Additionally, temperature sensors, batteries, timers and other important components that expand functionality can be built into the outlet.
Criteria for choosing a smart plug
When choosing a smart plug, you need to pay attention to the following:
- Availability of several SIM cards. There are models with two card slots. There is no need to change your phone number to receive an alert from the socket. Models other than two SIM cards are a more convenient solution.
- Battery capacity. Many types are equipped with lithium-ion batteries, allowing you to work in autonomous mode for a long time. It is worth choosing a variety with a battery capacity of at least 1000 mAh. Such a charge will allow all turned on electrical appliances to operate for at least 12 hours. This will allow you to monitor electrical devices during your daytime absence.
- Number of switching channels. This parameter is responsible for the number of devices that can be controlled from one outlet. This possibility indicates the practicality of the outlet. For example, the following can be connected:
- fridge;
- washing machine;
- laptop;
- TV;
- humidifier.
- Maximum power consumption per channel. This parameter is taken into account if devices that use high power (more than 2 kW) will be connected to the outlet. If the model does not have such capacity, then it will not work correctly. Example of high power devices:
- water heaters;
- electric stoves;
- electric ovens.
- Additional "chips". It can be:
- voice activation;
- voice notification;
- indicator signals;
- reboot from a distance.
Types of SMS controlled devices
Smart electrical outlets come in various types. They differ in functionality, appearance, number of controlled connectors, power, and type of control.
Ways to control SMS sockets:
- manual;
- via SMS messages and calls;
- with a WiFi control channel.
There are models that have all types of controls.
Kinds:
- network extender, in which each connector is controlled separately;
- gsm socket with 3, 6 or more lines for control via SMS;
- adapter socket for one device;
- unit for controlling three or more devices.
Functionality depends on the sensors that are installed in the electrical outlet. There are models with a door opening sensor, a gas leak indicator, a smoke sensor, and fire safety systems.
How to choose a smart plug?
In order for the purchase of a smart plug to be informed and confident, the following characteristics must be taken into account.
Notification numbers
Different devices may handle call alert functions differently. There may be one active number or two at once - sockets linked to one and two SIM cards are on sale. Obviously, devices that are capable of sending alerts to 2 numbers are much more convenient to use than those that can function with only 1 number.
How to buy the right GSM socket with advanced functions?
There are devices with additional capabilities. For example, the most advanced devices have the ability to perceive voice control, audio prompts, remote restart, remote listening and a status indicator. And similar convenient features.
Battery specifications
When purchasing, you need to analyze the capacity and type of built-in battery. Typically, such sockets operate with a Li-Ion battery. This battery allows the device to work without interruption and remain on for a long time. Choose devices with a battery capacity of over 1000 mAh. The activity time limit must be at least 12 hours. Such a powerful outlet will help regulate the supply of electricity to household appliances continuously. Even if you are away from home.
Outlet power
The limit on the load placed on the channel is important. This indicator determines the quality of operation of the device with high-power devices. When the switching load on the channel is negligible, then for safety reasons it will not be possible to use the outlet on high-power devices. This includes electric stoves and boilers. The permissible rated power is 2 kW.
Number of working channels
We need to find out how many switched channels there can be. A large number indicates the extreme practicality of the device. For example, working with 5 or more channels provides control of 5 devices - ionizer, air conditioner, refrigerator, computer, washing machine.
If you manage to choose a GSM socket with wide capabilities, you will be able to protect your home from force majeure circumstances that involve problems with power supply, network overloads and similar negative factors.
The GSM socket can be de-energized via a smartphone
Operating principle of a GSM controlled device
When a SIM card is installed in the gsm device, the outlet must be connected to the electrical network.
You can install any device that will be controlled in it. It is important to ensure that the electrical outlet is designed for the power of the equipment being connected. If control will be carried out via SMS, you should write the number in the phone book and create a message template with commands. When working through the application, you need to install the appropriate program on your smartphone. A link to it should be in the user manual or written on the box. After installing the program, you can start setting up.
Purpose
A smart socket is designed to facilitate the management of electrical consumers. Through the use of microprocessor technologies and wired and wireless communications, they can be controlled not only locally or remotely, but also to obtain information about the status and operation of various technical systems.
The following functions can be implemented in different designs:
- turning on or off various household appliances automatically with a timer strictly according to a schedule or via communications or the Internet at a distance;
- monitoring the status of security sensors, lighting, water leakage;
- temperature analysis and other tasks.
Correct installation of SMS device
After initialization, you need to configure the gsm device. You can do this yourself by following the instructions.
How to set up controls yourself
First of all, the numbers from which control occurs are established. You can add up to 5 master numbers in total. You can enable them in two ways – via SMS and through settings.
The commands required to set the number may vary depending on the model. In most cases, the phone number is added as #number#. A message is sent to the SIM card installed in the socket. The response will come in the form: “The number was successfully entered.” Passwords are set and commands are issued in the same way.
Phones can be added in the same way through the web interface. You just need to go to the appropriate section and enter the required numbers.
What does he do?
The Telemetrics company operates in the field of wireless security systems, remote monitoring and management. Since the start of operations in 2008, its specialists have created an extensive line of devices to solve these problems. The manufacturer’s devices are characterized by ease of operation, installation and configuration. In most cases, specialist help is not required. The user can quickly set everything up on their own by spending 5 minutes reading the instructions included in the kit.
The development of Telemetrics products is based on GSM-based remote control systems. In other words, to interact with them it is enough to use any mobile phone. There is no connection to any specific platform or device. Although, if you have an iOS or Android smartphone, interaction with technology is simplified thanks to a proprietary application.
Today we will talk about a new product - the T4 GSM-Socket, the compact case of which contains a full-fledged system for remote control of household electrical appliances.
Gsm device: features of choice
To choose the right smart plug, you should use the following tips:
- You need to pay attention to the manufacturer. It is better to buy products from well-known brands that have been tested by many users. Little-known Chinese products will not perform their functions fully and will last a shorter period of time.
- Look at the functionality. If a person only needs to turn an electrical outlet on and off on demand, it makes no sense to buy a model with many additional functions.
- Number of connectors. It is first necessary to decide which devices the user will control. Based on this number, a GSM socket with a suitable number of connectors is selected.
- Power. You should find out the total power of the connected devices and, taking into account the resulting load, select an outlet. The power reserve must be at least 30% of the rated value.
- Software You need to pay attention to the ability to set an operating schedule and select the temperature mode.
- You need to buy the device only in specialized stores that have licenses and warranty service.
- You should pay attention to the degree of security. For the kitchen you need to select models with a high IP level.
- The box should contain Russian-language instructions for use. If it is not there, the device was produced by an unreliable manufacturer, and it is not recommended to buy it.
Most modern models are equipped with a temperature sensor and timer.
Smart with SIM card and temperature sensor
Sockets with a temperature sensor can measure the microclimatic features of the room and send them to the user.
Using the device, you can prepare optimal conditions in advance - for example, turn on the heating or air conditioning. When the temperature value increases, a message will be sent to the user. When buying a socket with a temperature sensor, you need to visually inspect the device. It is advisable that the sensor is located outside the device body. Its location directly on the board threatens inaccurate measurements due to overheating during operation.
With timer
Recommendations for choosing an outlet with a timer:
- You need to decide on your purpose. For example, for short-term automation (watering plants), you can purchase a model with mechanical control. For long-term automation with an accurate schedule, you need an electrical outlet with a timer.
- When purchasing, you need to pay attention to the number of on-off cycles. Models from the mid-price category with electronic control can be turned on and off 5-7 times a day.
- You can purchase a device with the additional ability to generate random numbers. This option is used to simulate the presence of residents in the apartment by turning electrical appliances on and off. This helps protect your home from attempts by scammers.
A socket with a timer is not only a convenient device for controlling electrical appliances, but also an element of a security system.
The GSM power socket is designed to make the life of users easier and more comfortable. It makes it possible to remotely control equipment, work according to a given schedule, and control the temperature in the room. The smart socket can be controlled via SMS and via an application on a mobile phone. The controls are simple, anyone can use it.
