# Sonoff 4CH R3 WiFi Smart Switch

Sonoff 4CH R3 is a 4-gang Wi-Fi Smart Switch. In addition, it is designed to give you the ability to integrate smart control into your existing home. Furthermore, it has 4 gangs that can be used to control lights and other home appliances at the same time in four areas of your home.  
It is important to note that there is a major difference between 4CHR3 and 4CHPROR3, which is the 4CHPRO R3 is designed with an additional function for RF control.

Compared with 4CH R2, you can access self-locking, interlock and inching mode on the APP directly.  
The new improvement is for users to set these 3 working modes on eWeLink APP instead of the hardware itself, making it easier to operate.  
So you can enable self-locking mode to turn on/off 4 connected devices independently, interlock mode to turn on 1 connected device every time and turn off the rest of devices simultaneously and inching mode to turn on 1 connected device and then make it turn off automatically after a given time (0.5 – 3600s).
