This SONOFF device is a 4 gang SONOFF 4CHPRO R3 WiFi smart switch, DIN rail mount.

It allows you to connect and control 4 home devices, which can be turned on/off separately by the buttons or by the iOS and Android EweLink app. It is easy to hack and you can flash your firmware without difficulty. After accessing Google Nest, e-We Link can receive real-time environmental data like temperature, humidity from Google Nest, as well as check if there is someone at home or not. All this can be used to create a smart scene to control Sonoff devices supported by e-WeLink. Allows you to independently turn on and off 4 home devices Allows you to control home devices using local toggle buttons or the app Allows you to track the status of devices and control them remotely in a timely manner through the app Allows you to set up a countdown timer and calendar Allows you to share the device with another user using a single key.

The 4CHPROR3 is designed with an additional feature for RF control. This feature is specifically designed to allow you to turn on or off the device connected to the 4CHPROR3 via a 433 MHz remote control.


Remote control of lights or connected devices via APP
3 operating modes with auto-lock, lock and inching mode to remotely control garage doors and roller shutters.
Support for timer programming to have devices automatically start and stop operating.
Customize smart scenes so that the device connected to the switch triggers other devices.
Share device control authority with other accounts to control them together.
Check the on/off status of devices on your cell phone in real time.
Power status allows users to set the On/Off/Hold status of the connected device before a power outage and ensure that it remains in the expected state after power is restored.

Note: Each group of 4CHPROR3 can learn with 4 RF remote buttons. The 5th RF button will cover the first button that was learned, so 4 groups can learn with 16 RF buttons.

The new improvement of 4CHPROR3 over 4CHPR2 and 4CHPROR2 is that users can set these 3 operating modes on eWeLink APP instead of the hardware itself, which makes it easier to use. For example, you can enable self-locking mode to turn on/off 4 separately connected devices, interlocking mode to turn on 1 connected device at a time and turn off the rest of the devices simultaneously, and inching mode to turn on 1 connected device and have it turn off automatically after a given time (0.5 - 3600s). For devices far from the switch, you can create a mobile space with a DIN rail to connect them. Just activate the devices by voice when the switch works with Alexa and Google Home smart assistant.
