Description

The Sonoff RFR3 Intelligent Switch is a versatile AC power control module built for makers and smart home integrators. It combines 2.4GHz Wi-Fi (802.11 b/g/n) connectivity with a 433.92MHz RF receiver, allowing control via cloud services, local network, or physical RF remotes. Its core function is to safely switch high-power AC loads up to 10A/2200W, making it suitable for lamps, fans, and small appliances.

Engineered for reliability, the RFR3 features a local LAN mode within the eWeLink ecosystem, providing fallback control when cloud connectivity is lost. The module’s compact form factor and DIY-friendly design facilitate embedding into custom enclosures or retrofitting standard wall switches, enabling the creation of intelligent, voice-activated, and remotely managed devices without complex wiring or firmware development.

Key Features

  • Dual-Control Connectivity: Integrates 2.4GHz Wi-Fi for app/voice control and 433MHz RF for remote trigger functions.
  • Voice Assistant Integration: Works natively with Amazon Alexa and Google Assistant for spoken commands.
  • Offline LAN Mode: eWeLink local network control ensures operation without an internet connection.
  • High-Current Relay: Robust 10A relay safely handles inductive and resistive loads up to 2200W.
  • DIY Module Format: Compact board design allows for custom installation inside appliances or junction boxes.
  • Scene & Group Automation: Enables creation of automation rules and device groups within the eWeLink app.

Applications

  • Smart home lighting control for lamps and ceiling fixtures.
  • Remote power management for fans, space heaters, and small appliances.
  • DIY home automation projects integrating RF remotes with Wi-Fi control.
  • Creating scene-based triggers (e.g., turning on multiple devices with one command).
  • Retrofitting traditional wall switches or in-line cords for voice and app control.

Frequently Asked Questions

How do I set up the Sonoff RFR3 with my Wi-Fi network and Alexa?

First, power the RFR3 within its 100-240V AC range. Download the eWeLink app, create an account, and follow the in-app pairing instructions to connect the switch to your 2.4GHz Wi-Fi network. Once added, enable the 'eWeLink' skill in your Alexa or Google Home app, link your account, and discover devices. The switch will then appear for voice command control and can be grouped with other smart devices.

Can the RFR3 work without an internet connection?

Yes, the RFR3 supports a local LAN control mode within the eWeLink ecosystem. Ensure your smartphone is on the same local network as the switch. In the eWeLink app, you can control the device directly without cloud access, providing reliable operation during internet outages. The 433MHz RF remote functionality also works independently of Wi-Fi for basic on/off commands, offering multiple fallback control methods.

What is the purpose of the 433MHz RF receiver on the RFR3?

The integrated 433.92MHz RF receiver allows the RFR3 to be controlled by compatible wireless remotes or sensors. You can pair a 433MHz remote to directly toggle the switch, or use it to create automation rules where a remote button press triggers the switch. This enables scenarios like using a bedside remote to control a lamp or having a wireless door sensor trigger a light, adding flexible physical control options alongside app and voice commands.
