## Long description

Sonoff DUAL R3 is a compact smart WiFi switch module designed for 230V electrical installations. It provides two independent channels, each rated up to 1650W, with integrated dimming and per‑channel energy measurement. The module supports remote control via the Sonoff app, voice assistants through compatible integrations, local manual control, and scheduling for automated operation. Its energy monitoring capabilities help track consumption for each load, allowing more informed management of lighting and small appliances.
Advantages
The Sonoff DUAL R3 combines two high‑power channels in a single module, reducing the need for multiple devices in tight electrical boxes. Built‑in dimming enables smooth brightness adjustment for compatible lamps, while per‑channel energy measurement provides real‑time consumption data and historical usage statistics through the app. WiFi connectivity allows remote switching and scene integration, and local manual control retains basic operation if network access is unavailable. Compact form factor and standard 230V compatibility make the module suitable for retrofit and new installations.
Suitable for
Automating and dimming LED and incandescent lighting circuits

How to use

Connect live, neutral and the two load outputs according to the wiring diagram supplied with the module, then restore power. Add the device in the Sonoff app using your WiFi network credentials, configure each channel name, and set up dimming parameters if required. Use the app or supported voice assistants to switch channels, adjust dimming levels, and view per‑channel energy consumption. Local manual control remains available if physical access to the module wiring or wall switches is provided.
Usage recommendations
The Sonoff DUAL R3 is intended for use with lighting and small appliances within the specified per‑channel power rating. Ensure connected loads are compatible with dimming functionality before enabling dimming. For safe installation, observe national wiring rules and, if unsure, engage a qualified electrician. Regularly review energy reports in the app to optimise schedules and reduce unnecessary consumption.
