Scope and main functions

The remote control of the GSM socket allows it to be used in many areas.

Let’s highlight the main areas:

1. Heating system in the house, lighting in the country. On some models, temperature sensors are installed that allow you to equip climate control.
2. Appliances. The use of a GSM socket allows you to be aware of the status of electrical equipment (on / off). For example, using the device, you can remotely apply voltage to the boiler or restart the router.
3. Lighting. A smart device helps in adjusting the operation of lighting lamps. Its capabilities allow you to turn on / off the light by replacing motion sensors.
4. Watering. By giving commands to the GSM socket, you can start or stop the irrigation motor.

Above, only a part of the options for using a GSM socket for a smart home is considered. The ways to use it are limited only by the built-in capabilities and the imagination of the buyer.

In addition to remote control, such devices have a number of other functions:

1. Sounds when a certain temperature (minimum or maximum parameter) is reached. When an alarm is triggered, you can quickly call “emergency workers” and avoid negative consequences.
2. Temperature control in the room. The presence of this function allows you to maintain the microclimate in the room at a comfortable level.
3. Climate control. The essence of the option is to automatically adjust the temperature in the room during heating or cooling. In simple words, the temperature parameter is maintained at the same level.
4. The ability to set the mode. Thanks to this option, the appliance can be programmed to turn on / off after a specified period of time. For example, you can set the kettle to turn on 10 minutes before coming to the apartment from work.

The presence of such functions expands the capabilities of the outlet and makes it a really useful device.

Types

When choosing equipment, it is necessary to take into account its types. Let’s highlight the main options:

1. Standard network extension. Differs in the presence of two or more conclusions. To use you need a SIM card with a “plus” balance. After installing the SIM card in the device, check its operation by making a call or sending an SMS. The recommended application temperature is up to minus 20 degrees Celsius.
2. Single outlet. Suitable for connecting one electrical appliance.
3. Device with one output. It is used to connect gas sensors / door opening, fire safety, etc. Together with the socket, they create a security system against various force majeure situations.

Modern GSM sockets differ in additional options. They may include a shutdown timer, a thermal sensor, SMS recognition from a specific number, etc.

According to the control method, options are possible: using SMS and phone calls, with manual control and an additional control channel via Wi-Fi.

Devices are also divided into independent, slave and master sockets. The latter tend to control other devices (up to 10 pieces).

Устройство

GSM розетка имеет простое конструктивное исполнение.

It includes:

1. Frame. In appearance, it differs little from the standard fork.
2. Electronic board with SIM card slot and battery holder.
3. GSM-module to control the device via phone.
4. Input plug.
5. Output (euro-socket).
6. Control buttons.
7. Status indicators.

Structurally, the SMS socket may change slightly, but the general approach to execution remains unchanged.

How does work

At the first stage, you need to install a SIM card in a special slot and turn on the outlet. Once set up, it can be controlled via SMS, app or web service.

Consider them in more detail:

1. When choosing the first option, you need to enter the number of the card used in the smart device in the phone book. For more convenient use, you can make command templates.
2. Второй метод управления — через программу на телефоне. При поддержке такой опции на коробке должна быть ссылка или QR-код для скачивания. После загрузки программу необходимо установить и настроить.
3. The third way is management via the website. The user registers in a personal account, from which he controls the operation of the equipment connected to the GSM socket. Using the site, you can control the devices from anywhere where there is an Internet connection.

Some models provide a combination of all types of control.

Terms of use

Для корректного функционирования СМС-розетки необходимо соблюдать несколько условий.

Let’s highlight the main ones:

1. Minimum humidity in the room.
2. The absence of metal objects near the equipment, which is fraught with a deterioration in the quality of signal reception.
3. Mandatory grounding in the house with a device power of more than 1,5 kW.
4. Prohibition of connection on the street, near the stove / washbasin.
5. Accounting for the minimum distance between two smart devices.
6. Availability of optimal GSM-operator coverage.
7. Fine tuning if an external sensor is used.

Installing a GSM device is not recommended in rooms with medical equipment, where the use of mobile devices is prohibited, and where explosive elements are contained.

For the correct operation of the SMS device, it is necessary to memorize those phone numbers to which the device must respond. This feature avoids false positives.

SIM card preparation

To connect a GSM socket, you must have an existing SIM or buy a new SIM. When choosing the latter option, please note that some operators require SIM activation. To do this, just insert it into your smartphone and dial any phone number.

If you are prompted for a PIN code, disable the option to avoid blocking work in the event of a reboot.

Next, take the following steps:

1. Delete all contacts and SMS from the SIM card.
2. Check the balance of the card, which should be positive.
3. Install the temperature sensor in the special connector (if provided).
4. Insert the SIM card into the recess provided for this and press until it clicks.
5. Plug your device into a power outlet and memorize your phone. Send an SMS to #00# on the SIM phone installed in the socket.
6. Wait for a message about successful binding and equipment readiness for use.

According to the rules, it is forbidden to install / dismantle the SIM on the switched on device. Before performing this work, the device must be disconnected from the network and wait for all diodes to turn off.

Tariffs for GSM sockets

Devices are controlled using a GSM socket by communicating with a SIM card installed inside. That is why for the reliable operation of the equipment it is important to choose the right operator and choose the best tariff.

If the equipment is installed outside the city, you need to pay attention to the signal level.

In the absence of coverage, it is better to give preference to another operator, because you cannot count on stable and reliable operation.

When choosing a tariff, consider the following components:

1. Subscription fee. Today, many companies offer special services, including MTS, Megafon, Tele2, Beeline and others. In all cases, there are several tariffs available, the parameters of which change periodically. Before connecting, you must separately clarify this point.
2. SMS messages. This is a key parameter, because it is with its help that “communication” with the device takes place. Through messages, you can give a command to turn off the electricity, turn on / off certain sensors, exit the temperature range and solve other problems. The cheaper the SMS, the better, and the more money you can save.
3. Inbox. Today, almost all operators offer free calls, except when the SIM is outside the home region. In this case, the tariffs typical for roaming apply.
4. Outgoing. When using a GSM socket for heating, the device can call the subscriber’s phone. Such calls are rarely made, so the costs can be ignored.
5. Network connection. An Internet connection is not required. Therefore, please note that the operator does not activate any unnecessary package.

Currently, there are several options offered (tariffs are subject to change):

1. Megafon offers the “Go to zero” tariff. Calls within the region are not charged. There is no subscription fee. After connecting, all extra service packages must be “untied” for maximum savings. With active SMS sending, you can activate the SMS S option. In this case, you can send up to 100 SMS to phones in your home region.
2. Beeline. The best options are Zero Doubts and Signal with a small SMS cost. At the same time, the SMS package is provided free of charge. There is no daily subscription fee.
3. MTS. This provider offers Per Second tariff. You can immediately connect a package of SMS messages for 100 pieces.
4. Tele 2. Here the tariff is available Profitable set with no monthly fee and favorable conditions for customers.

Can I do it myself

If desired, it is easy to make a GSM socket with your own hands based on Arduino or using a GSM relay. This topic requires separate consideration, but we will consider a brief algorithm of actions.

Take the following steps:

1. Prepare the necessary tools. You may need a standard set. It includes screwdrivers, pliers and a current indicator. You also need a GSM relay if the assembly is based on it.
2. Insert the SIM card into the switch.
3. Route the necessary wires from the device to the electrical receivers. Fix the device in a place convenient for you.
4. Wait for the SIG LED on the relay housing to flash. This indicates a successful search for a cellular network.
5. Press the SET button until STA flashes, then release it and call the SIM within 30 seconds.
6. Выполните необходимые настройки с выбранного номера с помощью СМС-команд.
7. Set a master password that is set using an SMS command.
8. Connect the phase to COM and the controlled contacts to NO or NC. In this case, please note that in the case of switching on in NC, the device will always be on, and NO will be disabled until a control command is issued.

The main mistakes when assembling with your own hands are connecting a phase to NO or NS, trying to connect zero instead of a phase, and exceeding power. These and other errors can lead to equipment failure.
