Smart switches increase the comfort of living in apartments and private homes. They operate in automatic mode, do not require mechanical intervention to activate. Consider the features of the design and maintenance of these devices.
Principle of operation
The smart Wi-Fi switch is equipped with a receiver and a transmitter. The first node has a small relay, which is controlled using a remote control (remote control) or smartphone. After fixing the sent pulse, the device closes the electric circuit.
A miniature electric generator acts as a transmitter. When you press a key or send a command from the gadget, an electrical signal is generated that is transformed into radio pulses. In addition to recognizing the command, the device captures information confirming the execution of the order. Information is transmitted directly to the smartphone or controller responsible for the operation of the system.
Smart Switch Operation
The constructions under consideration give homeowners advanced opportunities for use. Using such systems, it is possible to adjust the light characteristics through a regular smartphone, laptop or other computer. An additional function is the programming of smart sockets and switches to automatically turn on or off at a specified time.
In addition, users can remotely monitor and control the lighting elements in their apartment. There is also the option of identifying a person. That is, if it enters the room, the light turns on, and when it exits, it goes out. A significant reduction in costs is ensured by the automatic activation of bulbs at a certain level of natural light. In some versions, the option of controlling the consumption of electrical energy is provided. Devices with dimmers allow not only turning the lamps on and off, but also regulating the intensity of lighting.
Pros and cons
Smart switches controlled by a smartphone have several advantages over traditional analogs:
- do not require laying a special route with wires;
- it is possible to control devices centrally from one point;
- device operation control is carried out from a smartphone, tablet, computer or remote control;
- significantly save electricity;
- impulse supply range up to 100 meters;
- wall ceilings do not interfere with the control of the system;
- these elements are able to function from a weak current that is not dangerous to humans in case of damage to the system.
Among the minuses note the need for a permanent Internet connection.
Devices with Dimmers
Many smart switches are equipped with a dimming function that allows you to adjust the brightness of the lighting elements. At the same time, the characteristic functionality does not change, including control using a smartphone. Dimmers expand the capabilities of switches.
They make it possible to create a comfortable atmosphere in the house, including light only when necessary. Dimmers are also used by interior designers to highlight room elements.
Devices with a remote controller
The device in question resembles a traditional analogue, however, it is controlled using the remote control. A smart light switch of this type consists of a frame and a key, does not require connection to the wiring, which allows you to mount the element anywhere in the room.
The device operates by transmitting radio waves to other devices. It always works in conjunction with additional devices. This can be an intelligent dimmer that reduces or increases the flow of light when receiving the appropriate command, or a smart socket.
Compatibility with other units
The autonomy of the smart switch depends on the design nuances. Devices with a Wi-Fi signal receiver are controlled directly from the phone without any additional devices. Analogs with Z-Wave or Zig-Bee systems need an additional controller that acts as an intermediary between the smartphone and the switch. An identical device is also used to store specified programs. For example, the range of automatic shutdown and inclusion of lamps.
Innovative technologies make it possible to mount an interactive system that includes several intelligent devices. The user can configure the switch in several modes, including the operation of the device when opening the doors by a sensor signal. The level of luminous flux, in turn, can affect the operation of other household devices, such as an air conditioner or humidifier.
Criteria for choosing a smart wireless switch
When choosing an intelligent device, it must be borne in mind that its correct operation is possible only if the Internet is available. Many modifications have an advanced option (compatibility with light or motion sensors). At the same time, their cost increases.
If the switch is planned to be installed outdoors or in rooms with high humidity, the protection of the device against liquid vapor must be taken into account. For work in conditions of special complexity, special models are chosen.
In the case of mounting an intelligent switch in a niche of a socket, the design of the device does not play a special role. The main thing is that the unit fits in the dimensions of the placed socket. Appearance, shape and fit into the interior are fundamental criteria when choosing such a device.
It is also worth paying attention to the following parameters:
- The quality of the device. It is better to purchase models from well-known and trusted manufacturers. The product should have clear lines of the case, a smooth surface, as well as a warranty card.
- The density of the polymer. Soft plastic versions scratch quickly and get dents. Hard plastic retains an aesthetic appearance for much longer.
- Existence in a set of special clamps and latches.
- The application in the form of a manual for operation and installation.
The nuances of connection and service
The installation of smart touch switches depends on the variety of lighting elements that aggregate with them. For a system with traditional incandescent lamps, the method is used, as with a conventional analogue. LEDs and energy-saving luminaires require wiring with phase and zero, which ensures safety during operation. Smart devices with an acoustic controller are installed in the niche of standard devices or next to a light source. Connecting smart switches does not cause much difficulty. You should first study the instructions supplied with the product.
