SONOFF - WIFI Smart Switch - 4 channels

SONOFF 4CHR3 is a 4-channel Wi-Fi Smart Switch designed to give you the ability to integrate smart control into your home. Each smart switch has 4 channels that can be used to control lights and other home appliances in four areas of your home simultaneously.

The new improvement in 4CHR3 compared to 4CHPR2 is for users to set these 3 working modes on the eWeLink APP instead of the hardware itself, which is easier to use. So you can enable self lock mode to turn on and off 4 connected devices separately, lock mode to turn on 1 connected device at a time and turn off the rest of the devices at the same time, and progressive mode to turn on 1 connected device and then let it run turns off automatically after a certain time (0.5 - 3600s). For the device removed from the light switch, you can use a DIN rail to create a mobile space to connect them. Simply activate the devices with your voice, if the switch works with Alexa and Google Home smart assistant.

Features

• Turn on/off all 4 devices connected separately in self-locking mode. Switch on 1 device but switch off the other 3 devices at the same time in lock mode. Switch on the connected devices but switch them off automatically after 0.5 to 3600 s in step mode.
• Mounted on the guide rail, convenient to connect and control devices away from the switch. Works with Alexa & Google Assistant & SmartThings & Alice.
