Technical summary
Description:
SONOFF 4CHR3 & 4CHPROR3 are both 4-gang Wi-Fi smart switches designed to give you the possibility of integrating smart control into your existing home to enable a smart home. Each smart switch has 4 gangs that can be used to control lights and other household appliances at the same time in four areas of your home. There is one major difference between 4CHR3 and 4CHPROR3, which is that 4CHPROR3 is designed with an extra function for RF control. The function is deliberately adopted to let you turn on/off the device connected to 4CHPROR3 via the RM433 remote control.
The new improvement on 4CHR3 and 4CHPROR3 compared to 4CHPR2 and 4CHPROR2 is for users to set these 3 working modes on the eWeLink APP instead of on the hardware itself, easier to use. So you can enable the self-locking mode to turn on/off 4 connected devices separately, the interlock mode to turn on 1 connected device at a time and turn off the rest of the devices simultaneously, and the inching mode to turn on 1 connected device, then have it turn off automatically after a given time (0.5 - 3600s). For a device far from the switch, you can create a mobile space under a DIN rail to get them connected. Simply activate the devices with your voice when the switch works with Alexa and the Google Home smart assistant.
