SONOFF 4CHPROR3 4 gang WiFi Smart Switch with RF

SONOFF 4CH Pro R3 is a 4-gang DIY Wi-Fi Smart Switch designed to give you the ability to integrate smart control into your existing home to enable a smart home. It has 4 gangs / electric circuits that can be used to control lights, wall plugs, AC and DC motors at the same time. 4CH PRO R3 is designed with an RF control function, so it can be also switched locally via Sonoff RF remote controllers. The smart relay supports 3 working modes including self-locking, interlock and inching mode. The new improvement on 4CHPROR3 compared with 4CHPROR2 is for users to set these 3 working modes on eWeLink APP instead of 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. The product is widely used to remotely control (typically 24V DC) gate or garage door openings, as well as 24V AC irrigation systems, as well as, manage 230V AC light and wall plugs.   4CH Pro R3 version compared with 4CH Pro R2 previous version :
