Sonoff MINI-ZB2GS-L Mini Duo-L Zigbee two-gang no-neutral module

A 2024-built flat has a two-gang switch but no blue wire in the box — the MINI-ZB2GS-L makes both lighting lines smart without a neutral, over Zigbee.

Sonoff MINI-ZB2GS Mini Duo Zigbee 3.0 two-gang in-wall switch module

Thirty Wi-Fi clients on the family router are plenty — this Duo keeps both lighting lines off the 2.4 GHz band, runs them over Zigbee and relays the mesh as a router.

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.

Matchbox-sized and 40% smaller than the ZBMINIL, the ZBMINIL2 tucks into the cramped box behind an existing switch and makes the light smart with no neutral.

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.

Hidden in the box behind a two-gang switch with no neutral, the Moes Zigbee module runs two light lines from the app while keeping the wall key.

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.

When a renovation already runs a neutral to every switch box, the ZBMINIR2 uses it to keep a light on local Zigbee — controlled by your hub, not a cloud.

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.

High-power 25A / 6000W smart relay with WiFi, Bluetooth and energy metering for water heaters, pumps and industrial equipment, no hub needed.
