Sonoff MINI-2GS Mini Duo Matter Wi-Fi 2-gang in-wall switch module

One Duo module behind a double rocker runs both lighting lines at once — chandelier and sconce keep their own wall keys yet switch independently via app or voice, 10 A per channel.

A glance at the relay tells you watts, volts, amps and total kWh on its built-in LCD — no phone required, with six months of hourly history kept in eWeLink.

POW Origin turns electricity-bill guesswork into hourly kilowatt-hour records — a week of eWeLink charts shows which appliance leads, with six months of history kept.

See what each of two loads really draws: the DUALR3 meters voltage, current, power and accumulated kWh independently per 10 A channel, with overload cut-off.

A boiler or a gate motor does not want 220 V from a relay — it waits for two signal wires to close, and the MINI-D dry contact does exactly that on app, schedule or voice command.

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.
