## Long description

Sonoff M5-3C-80 is a Wi‑Fi smart wall switch designed for installation in a standard wall box or in the Sonoff M-80 frame-holder (holder sold separately).

After setup, control each gang by pressing the mechanical buttons, via the eWeLink app, by voice through a linked assistant, or by scenes and schedules configured in the app.
Usage recommendations
For reliable operation, use on a stable 2.4 GHz Wi‑Fi network and avoid connecting loads exceeding the per-gang ratings. If multi-way control is required, pair with Sonoff Scene Controller R5 and follow wiring instructions to implement two-way or multi-way circuits. Ensure installation is performed by a qualified electrician according to local regulations.
