Sonoff smart switch is a household switch which can support Wi-Fi communication with your smartphone from long distance.
Sonoff Dual is a WiFi-based 2 gang switch that can connect and independently control two connected appliances or lights. This simply means 1 Sonoff Dual control switch equals to 2 Sonoff basic switches! Sonoff Dual 2 gang light switch inherits Sonoff Basic switch’s advantages such as easy installation and operation, quick WiFi access, remote control through APP EweLink.
In the application eWeLink, available on both iOS and Android, users can independently turn on/off each of the two connected devices. But the button on Sonoff Dual 2 gang WiFi light switch is not an ON/OFF toggle switch, it is only a WiFi pairing button. Users can set single/repeat/countdown timing schedules to turn on/off at a specified time, and also share with others so that they can control together.
