Sonoff MINIR4M Extreme Matter Wi-Fi smart switch relay module

A regular relay will not fit behind the switch in a shallow flush box — the 39.5×33×16.8 mm MINIR4M will, 40% smaller than MINIR2 and with a Detach Relay mode on top.

Tucked behind an existing 2-gang switch, this Matter-over-Wi-Fi relay joins Apple Home, Google Home and Alexa directly, with no extra gateway to buy.

Lighting a whole flat takes a relay per light point, so unit price decides: the Wi-Fi MINIR4 Extreme keeps 10 A and Detach Relay while costing less than its Matter sibling.

Countless DIY smart homes began with a cheap Sonoff Basic relay. The fifth generation keeps that recipe — one 10 A line, nothing extra — and now speaks Matter.
