The 4CH Pro R3 is an advanced Wi-Fi Smart Switch with RF control. Additionally, it is designed to integrate smart control into your existing home. Furthermore, it has four gangs that can be used to control lights and other home appliances in four different areas of your home simultaneously. Notably, the 4CHPROR3 has an additional function for RF control. This allows you to turn on/off devices connected with the switch via the RM433 remote controller.
Compared to the previous model, 4CH PRO R2, The Sonoff 4CH Pro R3 offers even more convenience. Subsequently with the 4CH PRO R3, you can easily access self-locking, interlock, and inching modes directly on the eWeLink app. This improvement allows you to set these working modes on the app instead of the hardware itself, making it much easier to operate. For instance, you can enable self-locking mode to turn on/off four connected devices independently, interlock mode to turn on one connected device every time and turn off the rest simultaneously, and inching mode to turn on one connected device and automatically turn it off after a given time (0.5 3600s).
