Relays and in-wall modules

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.

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.

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.

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.

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.

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