【Smart Wi-Fi Relay, No Hub Required】

Forget the hassle of additional hubs or gateways. The SONOFF DUALR3 connects directly to your home’s Wi-Fi network, making installation simple and seamless. Once installed behind a standard wall switch or socket, it transforms your existing setup into a Wi-Fi-enabled smart switch that you can control via the eWeLink app. From your smartphone, you can switch devices on/off, create schedules, or set timers — whether you’re at home or halfway around the world.

【Dual Relay for Two-Way Control】

Equipped with two independent relay channels, the DUALR3 allows you to control two different devices at the same time. This dual relay design not only makes it more versatile than standard single-channel switches but also enables two-way control, giving you the flexibility to manage devices from multiple locations.

Example applications include:

• Controlling two sets of lights independently.

• Managing different appliances from one module.

• Switching two motorized systems like blinds or shutters simultaneously.

【Three Flexible Working Modes】

The SONOFF DUALR3 offers three powerful operating modes tailored to your needs:

1. Switch Mode – Works like a standard smart switch, turning devices on and off via app, schedule, or voice command.

2. Motor Mode – Specially designed for motorized equipment like roller shutters, window blinds, awnings, and shades. You can fully open, close, or stop them at any position with precision.

3. Meter Mode – Offers real-time power metering, monitoring the energy usage of connected devices. This feature is ideal for tracking electricity consumption and optimizing energy efficiency.

【Smart Home Integration with Voice Control】

The DUALR3 is fully compatible with Amazon Alexa and Google Home, giving you the power of voice control. Simply say:

• “Alexa, close the living room blinds.”

• “Hey Google, turn on the kitchen light.”

No more reaching for switches — just effortless smart living with hands-free convenience.

【Power Metering for Energy Efficiency】

Unlike many smart relays, the SONOFF DUALR3 comes with built-in power monitoring capabilities. This allows you to track real-time energy usage, record consumption history, and gain valuable insights into how your devices are performing. With this information, you can identify energy-hungry appliances, reduce unnecessary usage, and ultimately save on your electricity bills.
