The Sonoff Dual R3 smart switch is suitable for anyone who wants to upgrade existing switches or electrical wiring in their home and integrate them into a smart ecosystem via a Wi-Fi network. It works best where you want to easily control lights, shades or other devices via an app on your phone or voice commands, without having to make major changes to the wiring. Before installation, it is recommended to check whether there is enough space in the box for the module and whether the existing switch supports such an interface.
