Sonoff Dual Smart Switch.JPG

Sonoff Dual is a 2-channel WiFi wireless switch that can connect and control two home appliances and electrical devices. This means 1 Sonoff Dual has combined 2 Sonoff basic switches! Sonoff Dual inherites Sonoff Basic switch’s advantages such as easy installation and operate, quick WiFi access, APP remote control.

In the APP EweLink for iOS and Android, you can independently turn on/off each of the two connected devices. But the button on Sonoff Dual is not an ON/OFF switch, it is only for long press to enter WiFi pairing state. You can set single/repeat/countdown timing schedules to turn on/off at a specified time, share to others so that they can control together.
