Sonoff 4-channel smart relay controlled by WiFi - 230VAC 2200W

Kõik toote kohta

Sonoff 4ch is a 4-channel relay controlled via WiFi via the eWeLink smartphone app or by the buttons on the device. Each channel can be controlled separately, and in the app you can give them the desired names, such as “kitchen”, “bedroom” and so on. Advanced users can reprogram the relay controller themselves, as the manufacturer uses the popular ESP8285 microcontroller.
The relay is easily mounted on DIN standard mounting rails.
The device also works with Amazon Echo, Google Home, and IFTTT smart systems.

Application and use:
● Remote control of the relay while away from home via the eWeLink smart app (relay requires WiFi connection)
● Real-time monitoring of device performance via the app
● Device control can optionally be granted to other app users
● You can set the time when the device will be turned on or off
● “Scene” mode - turn on or off a group of multiple devices simultaneously via the app
● “Smart Scene” mode - the relay can be turned on or off by other Sonoff devices
