What is Smart Switch?

Smart home systems are getting more and more popular every day. While the mobile devices we use increase our interaction with the outside world, they also increase the comfort of our home life.
Time is the most important opportunity offered by smart home systems, which continue to make the places we live in easily livable. The time we earn thanks to technological devices in home life becomes more valuable than many things.
When it comes to smart home systems, the first thing that comes to mind is that it saves us the time that people need to spend. For example, when a lamp needs to be lit, we may want to do this with a voice command. Or, we can ask for a curtain to be opened with a voice command. These examples can be multiplied.
With a mobile application on our phone, it became possible to process voice commands. We need intermediate elements so that these voice commands can give instructions to the devices we want to control.
The most used elements are smart switch. Many devices such as 220-volt lamps and curtain motors can be operated with voice commands with these smart switches, which receive instructions over the Wi-Fi protocol. Control is provided via Wi-Fi protocol with applications such as Google Alexa-Assistant, Amazon, TuYa mobile software on our mobile phone.
Wi-Fi, as it is known, is a worldwide RF protocol that uses the 2.4GHz frequency region. There are many Wi-Fi modules that use this frequency region. Modules such as ZigBee and ESP can be used in smart switches.
The simplest of the smart switches is produced with 1 Phase-1 Neutral input and a device output control end. There are also smart switches with 1 Phase-1 Neutral input, switch outputs, lamp control outputs, motor control outputs duplicated.

The GIRIER smart key shown in the picture is a ZigBee smart switch module controlled by Tuya. As it can be understood from the connection type, the control of two motors is provided with the smart switch provided with Phase and Neutral inputs. A lamp or other high-power device can be used instead of the motor.
