The module hides in the wall box behind an existing switch and turns an ordinary light or blind into something you can control. Sonoff MINIR4 and Shelly 1PM Mini Gen4 fit even a cramped box, and S-MATE2 manages without a neutral wire — a common obstacle in older houses. Separate products drive a ceiling fan (Sonoff iFan04-H) and curtains, where the SwitchBot motor runs along the existing rail. Before buying, check the permitted load in amps and whether you need the ZigBee or the Wi-Fi version.
