What is this - SMS socket?
The time has come when you no longer have to leave your keys with your neighbors when going on vacation/business trip. Now a smart device – an SMS socket – can control the air temperature in an apartment, office or country house.
It not only reacts to changes in temperature, but also notifies the owner about this by sending a message of appropriate content.
Design features of the device
Among the wide range of sockets, GSM-controlled models stand out. They are among the representatives of smart devices designed to make human life more comfortable.
So, if suddenly there is a loss of electricity at the dacha, the socket assistant will send an SMS to the owner about this event. There are models that will provide backup power in this case. And that's not all the possibilities of SMS-controlled sockets.
A GSM controlled socket is a device that visually resembles an adapter. Her appearance is quite presentable. This device from any manufacturer looks stylish and neat - you can safely use it in any interior.
The SMS controlled device has the following components:
- frame;
- internal components;
- additional sensors.
The body of a smart device of this type, regardless of the manufacturer, is made of high-quality plastic. This material can withstand high temperatures. But it will not protect the internal contents from moisture at all.
Most SMS sockets have a protection class of IP20. Therefore, it is strictly contraindicated to turn on such models if they can be irrigated with water, exposed to dust or direct sunlight.
On the front of the case there is a connector for connecting an electrical appliance plug with grounding and at least 3 indicators indicating:
- about connecting the outlet itself to the network;
- about the availability of GSM communication;
- about supplying power to the output.
Depending on the model of the device, there may be other indicators, the purpose of which can be read in the instructions included in the kit. There are devices controlled both via SMS and via the Internet. You can't do without a Wi-Fi indicator here.
On the back of the case there is a plug for connecting to the network, a slot for installing a SIM card from a mobile operator, closed with a lid, and additional buttons or switches are possible.
The button for manual control of the device, the input for enabling additional sensors and the service connector for data exchange can be located on the side or on the front side. It completely depends on the modification and imagination of the designer.
The internal contents of SMS sockets also depend on the model and its capabilities. The presence of a GSM module is mandatory for SMS-controlled models. Some modifications have a built-in battery, temperature sensor or other functional modules.
Often the kit comes with additional sensors - temperature, humidity, motion, noise level and others. Depending on the model, these sensors can be either physically connected to the device or contactless.
Those wishing to equip a smart home will certainly need SMS sockets smart switches, thoroughly analyzed and described in the article presented to your attention.
Types of SMS-controlled devices
Manufacturers of remote-controlled sockets delight their customers with new and more improved models. They keep the best features while adding additional useful features to the updated versions. And technological progress dictates its conditions.
All SMS sockets on the market differ from each other in functionality, appearance, number of controlled connectors, power, control method, number of slave devices and cost.
Depending on the number of functions performed and available control methods, the price of the device will vary. More skillful and capable models are much more expensive than their smart counterparts with a GSM control channel.
According to the method of controlling SMS, sockets are:
- with or without manual control;
- controlled via SMS messages and phone calls;
- with an additional control channel via Wi-Fi.
The most convenient models are those that provide the ability to use all 3 control options.
SMS controlled sockets come in different types:
- network extender, each socket of which can be controlled individually;
- controller unit with terminal blocks, mounted on a DIN rail.It is also often called a GSM socket, because it has 3, 6 or more lines controlled by SMS;
- a single socket in the form of an adapter with one connector for connecting one device;
- a single device or a block with sockets for connecting 3 or more devices that have a universal connector for various types of plugs.
A block with terminal blocks can hardly be called a full-fledged socket, because it has a completely different appearance and installation method. This GSM controller allows you to control the operation of devices connected on controlled lines.
It is completely incorrect to call it an SMS outlet. You first need to connect a regular socket to it, and then you can control its operation via GSM communication.
Depending on the control option, there are:
- independent models;
- controlling or they are also called master sockets;
- slaves - slave sockets.
The master socket can be subordinated to up to 10 slave models. They require one SIM card, because subordinates receive commands from the supervisor via a Wi-Fi channel.
All about the varieties and features of operation remote controlled sockets you will learn from the article, which we recommend you read.
Features of using a smart device
Having an SMS-controlled device at home, you can turn off the lights without getting out of bed, or turn on the coffee maker while in the bathroom. The socket receives a command in an SMS message and turns the device on or off accordingly.
This is not all of its capabilities. For example, you can program the watering of your garden plot to turn on if the air temperature and humidity are below or above a specified value.
Operating principle of a GSM-controlled device
A smart device that accurately carries out the commands it receives is deservedly in high demand in the socket market. After all, there are countless options for use - not only at home, but in the country and in the office. You don't need to be nearby to do this. It is enough to have a stable GSM connection from the desired mobile operator.
The command received in an SMS message from the owner leads to automatic closing/opening of the power circuit by the internal GSM relay of the socket. She sends a response to the owner of the house about the execution of the command. You can also send a command by making a call to the mobile number of the SIM card installed in the socket.
Correct installation of the SMS device
If we compare the socket with remote control via SMS with other smart brothers, we can highlight the ease of its setup and connection. Its installation can be handled by a person unfamiliar with electrical installation and who does not have special tools and skills.
First of all, even before purchasing a smart device, you need to make sure that the house where it will be installed has a stable GSM connection. Then you have to buy a mobile operator SIM card and the socket itself.Be sure to check that your tariff plan allows for sending and receiving messages.
Next, top up the account of the purchased card and disable the request for a password or PIN code at login. Now, having studied the instructions that come with the SMS socket, insert the SIM card into the appropriate slot. All that remains is to install the device at its workplace.
To use the SMS socket, you need to insert its plug into a regular socket to which you will connect an electrical device that requires remote control. After connecting to the network, the indicator light will light up, indicating this event.
That's all - the installation of the SMS-controlled device is complete.
Rules for setting up a GSM socket
After connecting the outlet to the network, you will need to configure the desired parameters. To do this, you need to make sure that the GSM module is working - the corresponding indicator light should be on. Now you need to bind the SIM card number to the device, following the instructions for the purchased outlet.
Depending on the SMS socket model, the nuances of its programming will differ. Everything will depend on the manufacturer, on what kind of outlet it is - independent or a set of master + slave.
To correctly set the desired parameters for a specific device, you need to study in detail the manufacturer’s accompanying instructions. This is important, because sockets from different companies are configured differently. Also, depending on the number of functions performed and additional sensors, the number of defined tasks for the device will differ.
Specifics of using the SMS device
For the most efficient operation of an SMS-controlled socket, you must follow certain rules for its use.
First, you need to carefully study the technical specifications, paying special attention to the maximum permissible load. After all, if you connect a heater consuming 3 kW to a socket designed for 1.5 kW, it will not withstand it and will burn out.
To protect yourself and your family, you should not exceed the maximum value that SMS sockets can withstand. Most often, this type of device is designed for 3-3.5 kW; it is rarely found at 5 kW. This characteristic must be contained in the instructions.
Secondly, you cannot connect such sockets outdoors, near a stove or washbasin. Water and dust will cause them to malfunction. And exposure to too high temperatures can cause internal components to explode.
The operating temperature of these devices is different - from -20 to +99 degrees. These values may vary depending on the model, but no SMS socket should be thrown into fire.
Thirdly, each model is capable of receiving commands from a certain number of control numbers. This depends on the individual technical features of each outlet. To prevent reactions to calls and messages from unknown callers, you need to enter the required numbers into the internal memory.
Some models of SMS sockets provide protection against random calls and spam mailings. They implement the function of receiving and responding only to those subscribers whose numbers are entered into the internal memory. All others will be ignored.It’s a pity that not all outlets have such capabilities.
Fourthly, if a set of main and slave sockets is used, then one should not forget about the maximum and minimum distance for their location from each other. The manufacturer indicates these values in the list of technical characteristics of the device. Otherwise nothing will work.
Fifthly, good GSM coverage of the operator is required. Without high-quality communication, remote control from a mobile phone is impossible.
Sixthly, if there are external sensors, you need to correctly configure the commands, using the instructions from the manufacturer, so that the socket works the way the user needs it.
Features of device selection
When choosing an SMS-controlled outlet for your home, you need to determine for yourself the basic criteria that it must meet. So, it is important to decide exactly what functions it will perform, because its cost will directly depend on this.
You also need to immediately decide how many and what kind of sockets you need to buy. This will be a block in the form of an extension cord for connecting a group of electrical appliances in one room, a master+slave set for placement in different rooms, or a single model.
If you just want to experiment with the capabilities of a regular SMS outlet, checking how it turns on and off a heater or an electric kettle/iron, then it will be enough to buy an inexpensive model with minimal capabilities. There is no point in overpaying for additional sensors and other bells and whistles.
In the case when you plan to leave a GSM-controlled socket at a dacha equipped with smart devices for control autonomous heating system and notifications about power failures, it is better to turn your attention to models equipped with a backup battery.
The capacity of the batteries can differ radically - you need to choose the one that suits the individual requirements of a particular consumer.
Owners will not need a smart plug GSM modules for boilers. Our proposed article describes in detail the process of controlling equipment remotely.
This is a good option that will allow the outlet to operate for several hours continuously from its own power source during a power outage. She will not only be able to send an emergency notification about what happened, but will also have time to turn on backup batteries, if they are installed in a particular country house.
Also, if you plan to use SMS sockets according to a specific schedule drawn up for a week/month in advance, then you need to choose models with non-volatile memory. So that a temporary lack of electricity does not disrupt the previously planned action schedule.
One of the important criteria when choosing an SMS controlled socket is its maximum workload. Here you have to take into account the power consumption of the device that will be connected through it. When purchasing a GSM controlled surge protector, you should take into account the maximum permissible load on each channel and the total load on the entire device.
It is strictly forbidden to exceed the maximum value specified in the instructions for the device. It is better if there is a power reserve of 30%.
Additional sensors and functions increase the cost of GSM sockets. But at the same time, they allow you to create additional conditions for comfortable work without putting in a lot of effort. For example, a built-in microphone and motion sensor will allow you to determine whether strangers are present in the office/home while the user is away.
SMS-controlled sockets are produced by many companies, both domestic, Western, and Chinese. The most popular devices are from manufacturers such as SenseIT, ReVizor, iSocket, ORCAM, Telemetrics, Sapsan, Smart Security, Proline.
Less user-friendly, but still demonstrating advanced advances in electrical installations switches with timer. We recommend that you familiarize yourself with the features of their operation, design and operating rules.

It is precisely the load limitation that is the main problem of SMS sockets. The fact is that many people buy them precisely for those points where kettles and irons are connected, since it is these devices that most often cause problems with fire hazards. As an alternative to such sockets, many devices have now appeared that connect to the Internet via the apartment’s wifi router. Which, it seems to me, has more prospects.
Wow, what a convenient outlet, I’ve never heard of these before! Perhaps it’s worth buying it for a dacha, where there are often interruptions in the heating system and therefore I’m afraid to even go to my neighbors’ house and leave the heating system on.Tell me, do these sockets themselves pose no danger? No more than normal? If you follow all the rules, then it cannot fail and suddenly turn on some of the electrical appliances?
This is the first time I have heard or even seen the sockets described here. How many different inventions have appeared that ordinary people don’t even know about. It reminds me of the smart homes of the future that are shown in movies. I wanted to put one in the kitchen so I could turn on the kettle or coffee maker while in bed. But I guess that such a gadget costs a lot, although it’s worth paying for the comfort of such details.
Good day, Sergey. SimPal-T4, remotely controlled via a mobile phone, costs RUB 3,600. The amount will quickly pay off if you often forget to turn off, for example, the iron. For Moscow residents, this is not money at all - imagine, having arrived 1.5 hours before work, you remember that the iron is heating up. The only way out, if family members are absent, is to fly by taxi.
By the way, when buying one, ask which operators the outlet works with - some, for example, are not controlled through Tele2 networks.
