Sonoff Dual R3

The Sonoff Dual R3 is a dual channel Wi-Fi smart switch with power monitoring. It controls two separate circuits independently, or one curtain motor, from anywhere using the eWeLink app or voice commands.

Why Choose the Sonoff Dual R3

Two channels in one compact module means you can automate two lights or appliances, or a motor that needs up and down outputs, with a single device hidden behind a switch or in a ceiling.

Power monitoring shows how much each load consumes, helping you spot waste and plan smarter schedules.

The Sonoff Dual R3 is also a favourite of integrators who already use SONOFF products, because every device appears in the same eWeLink app. Scenes can combine the dual switch with sensors, plugs and other controllers, so one tap or one voice command can adjust lighting, curtains and appliances together.

How to Choose a Smart Curtain Controller

First check the motor: most curtain, blind and roller shutter motors use a standard up/down/common wiring that works with smart curtain switches and modules. Next, decide between a wall panel, which replaces the existing switch, and a mini module, which hides behind it. Then choose the protocol: Wi-Fi connects directly to the router, while Zigbee needs a gateway but creates a stable mesh network in larger homes. Finally, consider extras such as RF remotes, voice assistants and percentage positioning.

Maintenance and Care

Clean touch panels with a soft dry cloth and avoid abrasive products. Recalibrate the travel time if you replace the motor or curtain fabric, and keep firmware up to date through the app. If a curtain stops early, check the motor limit settings before changing the controller.
