SONOFF 4CH Pro R3 – 4-Channel Wi-Fi Smart Switch with RF Control
Regular price $42.00

The SONOFF 4CH Pro R3 is a 4-channel smart switch designed to control up to four separate circuits independently. It supports control through Wi-Fi, 433.92MHz RF remote control, or the onboard buttons, making it suitable for various home and automation applications.

For applications where only one channel should be active at a time, Interlock Mode automatically turns off the other channels when a new channel is activated. Each channel also features individual NO, COM, and NC relay terminals for flexible wiring.

Key Features

  • Four-Channel Control: Operate four connected circuits independently.
  • Wi-Fi App Control: Control connected devices remotely and set timers.
  • 433.92MHz RF Support: Control the switch using a compatible RF remote.
  • Interlock Mode: Allows only one channel to remain active at a time.
  • Manual Operation: Dedicated buttons for channels R1, R2, R3, and R4.
  • Individual Relay Connections: Each channel provides NO, COM, and NC terminals.
