SONOFF 4CHR3 & 4CHPROR3 are both 4-gang Wi-Fi Smart Switches designed to give you the ability to integrate smart control into your existing home to enable a smart home. Each smart switch has 4 gangs that can be used to control lights and other home appliances at the same time in four areas of your home. There is a major difference between 4CHR3 and 4CHPROR3, which is that 4CHPROR3 is designed with an additional function for RF control. The function is purposely adopted to make you turn on/off the device connected with 4CHPROR3 via the RM433 remote controller.

The new improvement on 4CHR3 and 4CHPROR3 compared with 4CHPR2 and 4CHPROR2 is for users to set these 3 working modes on the eWeLink APP instead of the hardware itself, easier to operate. So you can enable self-locking mode to turn on/off 4 connected devices separately, interlock mode to turn on 1 connected device every time and turn off the rest of devices simultaneously, and inching mode to turn on 1 connected device and then make it turn off automatically after a given time (0.5 – 3600s). For the device away from the switch, you can create a moveable space by virtue of a DIN rail to make it connected. Simply activate devices through your voice when the switch works with Alexa and Google Home smart assistant.

【Independently/Mutual Control 4 Devices】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.

【Dry Contact】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.

【With 433MHz RF Control】Use your common 433MHz remote control to turn on/off the device without the internet.

【Easy To Out-of-Reach Devices】Mounted on the guide rail, convenient to connect and control devices far from the switch.

【Works With Alexa & Google Assistant & SmartThings & Alice】You can directly ask Amazon Echo/Echo Dot/Amazon Tap, Google Home to turn on/off your SONOFF devices.
