Smart devices are at the peak of their popularity these days. The main popular function is the ability to turn it off and on remotely via the Internet. But a more profitable solution looks like the ability to control the outlet, because this makes it possible to control all electrical equipment. In this article, we will consider this possibility in more detail.
How can such an opportunity be achieved at all. There are several possibilities to install such a device.
Relay and WI-FI sockets
A very convenient and versatile solution. Today, there are a huge number of such devices on the market. This is an adapter that plugs into an outlet.
Such a device works on the principle of a thermostat or timer. This model requires a WI-FI network. However, thanks to this, the user gets the opportunity to control the device not only from the home network, but also from anywhere in the world.
Additional functionality of the device includes safety sensors, the ability to meter electricity and other additional options.
Here are some well-known solutions:
TP-LINK HS110
The cost of such an outlet is $ 35. Using this model, you can take into account electricity consumption for the period of interest. Such an outlet is controlled directly from the body. There is also a special application for the OS "ANDROID".
TESLA SR16
This is a $ 21 device. This solution is considered universal, and can work as a timer, and perform the function of a voltage relay. Such an outlet is controlled remotely from any country.
BROADLINK WI-FI SP CONTROLS
The cost of this device is $ 25. To work, you need a special application for "ANDROID" or "IOS". This device has the ability to control by timer.
Radio relay
This method involves the use of a relay. Such a device can be installed either in the control device itself or directly in the junction box. Usually a radio relay contains a large number of channels. This is a fairly simple project.
The only disadvantage of this solution is in the small range. Different models use a different number of relays, the number of devices that will be accessed depends on this. Relays that have the ability to control several devices are called multi-channel. Several remote controls for radio control can be connected to such relays. They allow you to customize the light control from different places without any problems. They do not require complex circuits and do not need to redo the wiring.
GSM systems
Such a device allows you to control the outlet over the cellular network. This is the most difficult and costly option. If you still choose this method, then the easiest way is to purchase a ready-made solution. In this case, only the initial configuration of the equipment is required. For their work, these devices imply the use of SIM cards. This introduces certain inconveniences and extra costs, because the SIM card must be constantly replenished.
Here are examples of prices for such devices
- SOKOL-GS1.
This solution costs about $ 30. To control it, you need to dial the number of the SIM card, which is in the device. The answering machine will give a report about the state of the device, and you can also give it certain commands.
- INTERVISION GSM SMART SWITCH.
This solution costs about $ 45. In order to turn on this device, you need to send an SMS with a special code.
- TESLA SECURITY GSM-POWER.
This option costs $ 85. A thermal sensor can be connected to such a model. In this case, the device will inform you about the air temperature via SMS.
- COMPUTHERM GSM158.
This outlet costs $ 95. A distinctive feature is the ability to manage multiple telephone numbers. You can also set up a timer and assign a specific day of the week to turn on the outlet.
