Remote control of electrical appliances gsm. Remote power management
What is the limit modern means automation? This article will shed light on the issue remote control home power network using a GSM/GPRS signal. Turn on landscape lighting in the country by sending an SMS, or have a complete interactive diagram of the entire energy system at home - it is possible thanks to new technologies.
The remote power management system can be used in both country houses, and in apartments for the purpose of remote switching on of heating, lighting control, creating the effect of presence at the time of departure, and so on. You can establish control in any power grid, including an existing one. The technology is based on the operation of logical controllers that receive commands via one of the GSM/CSD/GPRS communication channels and execute either them or the command scripts corresponding to them.
Hardware Overview
The first step to remote power management is purchasing the right hardware. A complete power management system consists of five components, for each of the points a sample will be selected for drawing up an assembly diagram:

Remote control systems also use a variety of peripheral devices:
- UPSs remain operational when the power is turned off.
- Relay automation units make the execution of commands safe.
- Programming scripts expand the controller's capabilities.
- Wireless communication modules allow for unlimited expansion of the system.
- User graphical interfaces allow you to configure the equipment without connecting to a PC.
Typical connection diagrams and ready-made solutions
It is almost impossible to list all the possible uses of GSM controllers in the household. Modern SCADA systems are so diverse that they can solve any household problems without exception. Standard complexes, such as KSITAL GSM or ESIM120, do an excellent job with common tasks like lighting or heating control. Everything is simple with them: the controller is installed at the actuator and controls the power through the relay output.
Cons: you have to supply each node with a separate control module, and this is confusion with mobile numbers, limited capabilities and the lack of a single control center.
There are more advanced versions of the circuits, but you will have to assemble them yourself. Consider only some typical options.
The controller performs the task of greenhouse and garden irrigation, connected to common system control, through it is also controlled remotely. It is possible to execute both commands and program scripts. Relay interlock will prevent crash if user error occurs.
A powerful freely programmable controller and several I/O modulators control all systems in the house, including burglar and emergency alarms. This is one of the most advanced schemes that can be successfully integrated into a smart home system.
Sometimes a single device is enough, which is both a modem, and a controller, and an I / O module. Control scheme based on ES-ForthLogic communicator.
SMS exchange, Android app or remote desktop
It is better to decide in advance how advanced the user interface of the remote control system will be. If we are talking only about heating, a simple SMS exchange will suffice, during which the codes of commands are transmitted to the boiler, to which it responds either with a report or by turning on the actuator. Command codes may be pre-installed in the device, although most devices can change the default values.
More advanced interfaces use data exchange via a GPRS server. The user can use any of the available control channels. For example, when he is away from home, he can control the controller through a Windows utility, monitor the system status through an Android application, and use CSD dialing to open the gate.
Concerning software devices themselves, they are not amenable to strict classification and critical evaluation. The fact is that each manufacturer uses its own development environment. Naturally, each device is provided with a detailed manual for programming, configuration and parameterization, but it can be quite difficult to understand it. The situation is aggravated by the partial incompatibility of equipment from different manufacturers with standard program memory presets. Of course, no one bothers to try your hand at logic programming, and in case of failure, turn to an experienced specialist.
From theory to practice - an example of a simple but functional circuit
The ES-ForthLogic communicator was mentioned above, as well as a list of devices, including a modem, a controller, and an I / O module. Consider them as an assembly example and see that the capabilities of individual solutions are superior to typical automation solutions.
Assembly is carried out in a modular box for 36 places: first, power wiring and switching equipment are mounted, then telemetry devices and low-current conductors are installed. Wiring diagram assemblies:
This assembly allows you to remotely activate any of the operating modes of the pumping station in the pool, heat the water, fill the heating system with coolant and heat the room, turn on the watering of the lawn or individual sections drip irrigation, illuminate the yard and yard, activate the procedure for walking or feeding dogs. The beauty of the assembly is that it is quite simple and interesting to program using the manual, because all the elements are fully compatible.

The company "GEOMAKS" offers to buy a temperature sensor with a GSM module. This device It is designed to control the temperature regime at a protected facility. It is widely used in residential and warehouse premises, greenhouses, incubators, cellars, garages, etc. Such sensors allow you to control the situation near heating and heating equipment. They are also an important component of systems " smart House».
Our range includes GSM temperature sensors, which have high sensitivity and reliability. You can buy them at the best prices and with the possibility of delivery in Moscow and Moscow Region by our company's own courier service. For the convenience of customers, we offer several payment options and provide professional assistance in choosing the right equipment.
Features of GSM temperature sensors
The device provides continuous temperature measurement in the controlled area and its continuous comparison with the threshold value, which is recorded in the product memory. When the limit value is reached, the sensor gives an alarm signal using an SMS message or dialing to the phone numbers of the owners. This allows you to protect property from fire and other unforeseen situations.
GSM temperature sensors have the following advantages:
- the possibility of remote control using special service SMS commands. With their help, you can get information about the temperature regime, turn off electrical appliances, etc.;
- wide operating temperature range and stable readings;
- possibility of integration into integrated system security. This allows you to automatically call the fire brigade when the permissible temperature is exceeded, maintain the temperature at a given level, turning the heating on and off;
- the ability to work both offline due to the built-in battery, and from an external power source;
- all the necessary software for the operation of the GSM temperature sensor is already installed in the flash memory of the device;
- versatility of application on various objects.
GSM automation for comfort
How often do you forget to turn off electrical appliances? Or maybe on the contrary, you wanted to turn them on before you come home? But in order to turn off the iron forgotten at home, you will have to return home. Is there any other way to get out of this situation?
In the age of high technology, to this day in apartments you can find traffic jams that are almost older than the apartment itself. Automation comes to our homes with some great difficulty. Everything works and thank God. Probably, it is this slogan that the vast majority of residents use. But there are people who bring comfort into their lives, drop by drop, but they do it. I am one of those people too. I don't know why, but everything is interesting. I most often see the benefits of acquisitions after I have purchased a new appliance.
So today we will talk about GSM. More precisely, not even about him, but about how with his help we can manage something. If we do not go into such a serious topic as a smart home and go the easier way, then on the market we can find a number of devices that in one way or another can control appliances in our home. I love modular DIN hardware. I love it because DIN is the international standard for installation products in shields. All of them have the same dimensions and their installation is as simple as assembling a Lego set.
What is GSM control for?
You can easily figure out how to use the device to control devices from your phone. Its main task, as the name implies, is load management. This is to turn them on or off. In other words, it's just a switch, but we can control it with cell phone. With this device, we can control absolutely any load in the on and off mode.
For example, in the country. We have an introductory shield that distributes electricity throughout the cottage. Hurrying home, you can forget to turn off the introductory machine, and, accordingly, the included appliances, such as a fireplace, will remain working. Having already reached the house, you remember about it, and the dacha is 100 km away. Come back and off? Of course, otherwise the cottage can very quickly turn into a pile of ashes. And you can set the load control using your phone and turn everything off using your phone.
The same can be done in an apartment. The main thing is to divide the electrical wiring in advance so that the refrigerator and other important appliances do not turn off. Which ones are up to you. Although almost every GSM relay can control several load groups and, accordingly, several commands, we can turn on and off different groups. The electrical panel can be configured to disconnect the entire load EXCEPT and ABSOLUTELY the entire load. To do this is quite simple.
Most of these devices are equipped with a temperature sensor input, so we can remotely control the heating devices in the room. Thus, heating will not work constantly, but only when we need it. So we can also save electricity with it.
At the same dacha, we can remotely turn on the underfloor heating or fireplace in advance in order to arrive in an already warm room, and since the device is equipped with its own sensor, it will send you an SMS in advance when the temperature reaches the desired one.
Also, using the GSM module, you can remotely control irrigation, pumps and lighting. The application options are endless. After all, the main thing that these devices can do is to control the load. And this is exactly what we need - to comfortably and remotely turn on or off certain electrical appliances. We want to do this for various reasons. Someone because of forgetfulness, someone wants to turn something on in advance.
For those who forget to turn off the light and iron, as well as for those who want to arrive in advance to a warm cottage even in winter. Who can't come to water their favorite flowers three times a week and don't want them to dry up. Automation has been in our lives for a long time and is only gaining momentum, you see, it is very convenient. And how much joy people experience when they begin to manage such seemingly complex technologies with their own hands.
