Description

The Sonoff Dual R3 is a professional-grade, Wi-Fi-enabled smart relay module designed for home and light industrial automation. Built around the ESP8285 system-on-chip, it provides reliable 2.4GHz Wi-Fi connectivity and two fully independent relay outputs, each capable of switching up to 10A at 220V AC. This allows for the remote control of two separate high-power circuits, such as lighting, appliances, or motors.

Its core functionality is managed through the eWeLink ecosystem, enabling seamless integration with major smart home platforms like Amazon Alexa, Google Assistant, and Apple HomeKit via Siri. The module supports advanced features like scheduling, countdown timers, and scene creation, facilitating complex automation routines without requiring a dedicated hub. The compact form factor and DIN-rail mounting option make it ideal for discreet installation within standard electrical enclosures.

Key Features

  • Dual-channel high-power relay control for independent operation of two AC circuits.
  • ESP8285-based Wi-Fi connectivity enables direct cloud and local network control.
  • Full compatibility with eWeLink app for remote access, scheduling, and scene management.
  • Voice control integration with Amazon Alexa, Google Assistant, and Apple Siri/HomeKit.
  • Supports timer functions, countdowns, and device sharing with family or team members.
  • Safe operation with AC 100-240V input and robust relay isolation.
  • Compact and discreet design suitable for DIN-rail mounting in electrical boxes.

Applications

  • Smart home lighting control for two separate rooms or zones.
  • Remote switching of high-power appliances like heaters, fans, or pumps.
  • Automation of garage doors, motorized gates, or window shades.
  • Light industrial control for machinery or signage on schedules.
  • Integration into DIY home automation systems using eWeLink or local API.

Frequently Asked Questions

What is the maximum load each relay channel on the Sonoff Dual R3 can handle?

Each independent relay channel on the Sonoff Dual R3 is rated for a maximum resistive load of 10 Amps at 220 Volts AC, equating to 2200 Watts. The module's total maximum combined load for both channels operating simultaneously is 15A or 3500W. It is designed for standard incandescent, LED, and appliance loads within these specifications.

How do I connect and set up the Sonoff Dual R3 with my home Wi-Fi and smart assistants?

First, wire the module's AC input (L/N) to your mains power and connect the load wires to the relay output terminals. Download the eWeLink app, create an account, and follow the in-app pairing process to connect the device to your 2.4GHz Wi-Fi network. Once online in the app, you can link your eWeLink account to Amazon Alexa, Google Home, or Apple HomeKit to enable voice control and automation routines through those respective platforms.

Does the Sonoff Dual R3 support local network control or automation without the cloud?

While primary control is facilitated through the eWeLink cloud service for remote access, the ESP8285 chipset is capable of supporting local network control. Advanced users can potentially flash custom firmware like Tasmota or ESPHome via serial connection to enable full local MQTT control, removing cloud dependency and integrating the switch into open-source home automation platforms like Home Assistant for increased privacy and reliability.
