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 at the same time in four areas of your home.
The new improvement on 4CHR3 over 4CHPR2 is for users to set these 3 working modes on the APP eWeLink instead of the hardware itself, easier to use. So you can activate the self-locking mode to turn on/off 4 separately connected devices, the lock mode to turn on 1 connected device each time and turn off the rest of the devices simultaneously and the progressive mode to turn on 1 connected device, then turning it off automatically turns off after a given time (0.5 – 3600s). For the device away from the switch, you can create a mobile space with a DIN rail to connect them. Just activate devices by your voice when the switch works with Alexa and the Google Home smart assistant.
- Turn on/off the 4 connected devices separately in self-locking mode. Turn on 1 device but turn off the other 3 devices at the same time in interlock mode. Turn on the connected devices but automatically switch off after 0.5-3600s later in inching mode.
- If your device does not need to be powered through the output of the 4CHPROR3, but only needs to use it as a smart switch to control the line on and off, the 4CHPROR3 is your best choice.
- Use your common 433MHz remote control to turn on/off the device without internet.
- Mounted on the guide rail, convenient to connect and control devices far from the switch.
- You can directly ask Amazon Echo/Echo Dot/Amazon Tap, Google Home to turn on/off your SONOFF devices.
