4 Channel Wi-Fi Smart Switch
SONOFF™ 4CHR3 Overview
SONOFF 4CHR3 is a 4-gang Wi-Fi Smart Switch designed to give you the ability to integrate 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 home appliances at the same time in four areas of your home. The earlier version 4CHR2 had different 3 working modes, namely, self-locking, interlock and inching mode. The improvement in 4CHR3 is that users can set these 3 working modes on eWeLink APP instead of the hardware itself, and hence 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 a device that is located away from the switch, you can create a moveable space by virtue of a DIN rail to facilitate them to be connected.
Simply activate devices through your voice when the switch is configured to work with Alexa or Google Home smart assistant.
