SONOFF 4CH (R3) is a 4-gang Wi-Fi Smart Switch designed to give you the ability to integrate smart control into your existing home. Each smart switch has 4 gangs that can be used to control lights and other home appliances at the same time in four areas.
There is a major difference between 4CH (R3) and 4CH PRO (R3), which is that this 4CH (R3) is designed without function for RF control. So, if you want to turn on/off the devices connected via the RM433 remote controller, then you should go for the 4CH PRO (R3) version.
Sonoff 4CH Pro R3 is the new 4 gang WiFi switch with 3 working modes including self-locking, interlock and inching mode. The new improvement on this R3 version compared with the R2 version is that users now can set all 3 working modes on eWeLink APP instead of in the hardware itself - easier to operate! So you can enable self-locking mode to turn on/off 4 connected devices separately, 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).
For the device away from the switch, you can create a moveable space in virtue of a DIN rail to make them be connected. Simply activate devices through your voice when the switch works with Alexa and Google Home smart assistant.
