Sonoff 4CH R2 is a 4-channel WiFi wireless switch that can connect and control four home appliances and electrical appliances. The switch allows you to independently turn on / off each of the connected devices and set single / cyclic / countdown schedules of on/off. The control is carried out using the transparent eWeLink application available for Android and iOS platforms. The device is compatible with Amazon Alexa and Google Home and supports the IFTTT service.
