Product Information

Sonoff 4CHPRO R3 — 4-Channel Smart Switch

The Sonoff 4CHPRO R3 lets you control up to 4 devices or circuits independently from one unit. Install it in your electrical panel, and you can turn each connected device on or off from your phone using the eWeLink app — whether it’s lights, a water pump, fans, or appliances.

It also supports RF 433MHz (radio Frequency remote control — works without Wi-Fi or internet, like a TV remote) remote control, so you can operate it without internet using a Sonoff RF Remote.

Key Features:

  • 4 Independent Channels: Control 4 devices separately — turn one on while keeping the others off.
  • Multiple Modes: Self-locking (normal on/off), Interlock (turn one on and the other 3 off automatically), and Inching (turns on for a set time then turns off — great for garage doors).
  • Dry Contact Support: Works as a simple smart switch to control signal lines — ideal for gate openers, alarms, and boilers.
  • Mounts on DIN rail: Designed to be installed inside your electrical panel.
  • RF Remote Control: Use a 433MHz remote to control devices without internet.
  • Voice Control: Works with Google Assistant and Alexa.

💡 Pro Tip: Use Interlock mode if you have two water tanks and want only one pump running at a time — it automatically shuts off the other when you activate one.
