The Sonoff Dual R3 is a smart Wi-Fi dual relay switch module that transforms traditional switches into smart switches for remote control and automation. Designed to be installed behind standard wall switches, this compact device supports switch mode, motor mode, and meter mode—ideal for controlling roller shutters, window shades, and other motorized appliances.

With two independent relay channels, it allows for two-way control of two devices separately. The built-in power metering function provides precise energy usage data to help reduce electricity costs. Additionally, the Dual R3 is compatible with multiple switch types and can be controlled via the eWeLink app, Alexa, or Google Home for seamless smart home integration.
