Sonoff 4CH Pro Smart Switch

Experience the power of versatile and convenient home device control with the Sonoff 4CH Pro Smart Switch:

  • Independent/Group Control for 4 Devices: Seamlessly turn on/off four connected devices separately in self-locking mode. Activate one device while simultaneously turning off the other three devices in interlock mode. Set up connected devices to automatically switch off after a specified time in inching mode (ranging from 0.5 to 3600 seconds).
  • Dry Contact Support: If your device doesn’t require power through the switch but relies on line control, the 4CH Pro R3 is your perfect choice.
  • 433MHz RF Control: Utilize your common 433MHz remote control to manage device operation without the need for an internet connection.
  • Easy Control for Out-of-Reach Devices: Mount the switch on the DIN rail for convenient connection and control of devices located far from the switch.
  • Voice Control Compatibility: This smart switch seamlessly integrates with Amazon Alexa and Google Assistant. Instruct Amazon Echo, Echo Dot, Amazon Tap, or Google Home to effortlessly activate or deactivate your Sonoff devices.
  • Versatile Application: The 4CH Pro Smart Switch is designed to give you the ability to integrate smart control into your existing home. It features four relay/switches that can be used to control lights, sprinkler solenoids, garage motors, and other home appliances.
  • RM433 Remote Controller: Control the switch via the RM433 remote controller, enhancing convenience and flexibility.

Please note that the switches require a neutral wire, 2.4GHz Wi-Fi, and an internet connection.
