4 Channel Smart WiFi Switch with RF Control

Sonoff 4CH R3 is a 4-gang rail mount switch.

It supports connecting and controlling 4 electrical appliances, which can be turned on/off separately via buttons or EweLink app. 

The enclosure is supported for rail mounting! Standard type metal rail widely used for assembling circuit breakers and industrial control equipment inside equipment racks.

These products are typically made from cold rolled carbon steel sheet with a bright galvanized or chrome plated surface finish.

With EweLink app, you can turn on/off from anywhere at any time, and at any time you can set single/repeat/countdown schedules to turn on/off at a specific time and share with others so that they can control together 

The new improvement on 4CHR3 and 4CHPROR3 compared with 4CHPR2 and 4CHPROR2 is for users to set these 3 working modes on eWeLink APP instead of the hardware itself, more easy to use. So you can enable self-locking mode to turn on/off 4 connected devices separately, interlock mode to turn on 1 connected device each time and turn off the rest of the devices at the same time, and inching mode to turn on 1 connected device and then make it turn off automatically after a certain time (0.5 – 3600 seconds). For the device far away from the switch, you can create a movable space by virtue of a DIN rail to make them connected. Just turn on the devices by voice when the switch works with Alexa and Google Home smart assistant.
