SONOFF 4CHR3 is a 4-gang Wi-Fi Smart Switches 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.
The modes included on the R3 model includes Self-locking mode to turn on/off 4 connected devices separately, Interlock mode to turn on only 1 connected device at a given time and inching mode to turn on a connected device and then make it turn off automatically again after a given time (0.5 – 3600 seconds).
The 4Ch R3 can also be fitted to a DIN rail for applications where remote devices are connected via cables to a central point.
Connected devices can then be controlled via voice (Alexa and Google), form a smart phone via the free app, and setting time schedules.
Wi-Fi connectivity enables users to remotely turn this switch on or off from anywhere in the world via the free app, e.g. switch on interior home lights before leaving the office or set a timer to switch exterior lights on at 8pm every night and off at 5am.
Users can also create 8 enabled single, repeat or countdown timers to automatically turn on/off at the specified time. Timers will run even when the network is unavailable.
Access to control switches can easily be shared with other users via the free eWeLink app.
