Sonoff 4CH Pro R3 is a WiFi switch with 4 outputs that can be configured as a diverter or timed button,
both independently and interlocked with each other.
SONOFF 4CHR3 and 4CHPROR3 are both 4-band Wi-Fi smart switches designed to give you the ability
to have control of your home to make it a smart home.
Each smart switch has 4 bands that can be used to control lights and other appliances at the same time in four areas of the house.
There is a big difference between 4CHR3 and 4CHPROR3, i.e. the latter is designed with an additional function for RF control.
The function is deliberately adopted to turn the device connected to 4CHPROR3 on / off via the RM433 remote control.
Actually Sonoff has already released two types of smart switches (4CHR2 and 4CHPROR2) which have almost the same functions as these.
However, all of the above units are different in the 3 working modes, including self-locking, interlock and inching.
The new improvement over previous models is that users set these modes on the eWeLink APP instead of the hardware itself, so it is easier to manage.
You can allow self-blocking to turn on 4 connected devices separately, interlock to turn on one connected device each time and turn off the rest
of devices at the same time and to the inching of turning a device on and off automatically after a certain period of time (0.5 - 3600).
For the device away from the switch, a movable space can be created by virtue of a DIN rail to connect them.
Simply activate the devices via your voice when the switch works with Alexa and the Google Home smart assistant.
