SONOFF - Wifi Smart Switch - 4 channels

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

The new improvement of 4CHR3 over 4CHPR2 is for users to set these 3 operating modes on the eWeLink APP instead of the hardware itself, which is easier to use. Thus, you can enable the auto-lock mode to turn on and off 4 connected devices separately, the blocked mode to turn on 1 connected device at a time and turn off the rest of the devices at the same time, and the progressive mode to turn on 1 connected device and then let it work turns off automatically after a while (0.5 - 3600s). For the device away from the switch, you can create a moving space using a DIN rail to connect them. Simply turn on the devices with your voice if the switch works with Alexa and the Google Home Smart Assistant.

DUTIES

• Turn on/off the 4 separately connected devices in self-locking mode. Turn on 1 device but turn off the other 3 devices at the same time in lock mode. Turn on connected devices but turn them off automatically after 0.5 to 3600 s later in step-by-step mode.
• Mounted on guide rail, convenient to connect and control devices away from the switch. Works with Alexa & Google Assistant & SmartThings & Alice.
• You can directly ask Amazon Echo/Echo Dot/Amazon Tap, Google Home to turn your devices on/off SONOFF.
