Sonoff MINI Matter Wi-Fi Smart Switch (ONE 1-Gang / DUO 2-Gang) | MINI-1GS

The SONOFF MINI ONE and MINI DUO are compact in-wall smart switch modules from the MINI Extreme series with Matter over Wi-Fi. They fit in the wall box behind your existing switch, keep the wall switch working, and add app, voice and automation control in Apple Home, Google Home, Amazon Alexa, SmartThings, Home Assistant and eWeLink.

Two versions are available: MINI ONE (MINI-1GS) controls one circuit of up to 16A, and MINI DUO (MINI-2GS) controls two lights or circuits independently (10A per channel, 16A total).

Matter over Wi-Fi: Both modules join Matter platforms directly by scanning the Matter QR code, so they work in Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant, and also in the eWeLink app. Voice control works through the assistant of your platform.

MINI ONE – 16A and Local Control: MINI ONE handles up to 16A (3840W), enough for loads such as storage water heaters or underfloor heating. It has SONOFF's OpenEdge web console for setting up and controlling the switch from a browser on your local network, plus an open API (JSON-RPC 2.0 over HTTP, WebSocket and MQTT) and Home Assistant integration through MQTT Discovery.

MINI DUO – Two Loads in One Module: MINI DUO has two independent channels (L1 and L2) with two switch inputs (S1 and S2), so one module can run two lights in the same room, each from its own wall-switch button or from the app.

Detach Relay: Both versions support Detach Relay mode, which separates the wall switch from the relay. The physical switch then acts as a smart trigger for scenes while smart bulbs on the circuit stay powered. On MINI DUO this mode is available in the eWeLink ecosystem.

Power-On Behaviour & Scheduling: Choose whether the switch returns to its last state, turns on or stays off after a power cut; MINI ONE also offers a delayed power-on to protect loads when power returns. Timers, schedules and smart scenes are set in your app.

Safety: Both modules have built-in overheat protection that cuts power when excessive temperature is detected. MINI DUO also adds surge protection in a flame-retardant PC housing.

Who it's for / Works with: Anyone upgrading existing wall switches without changing them. Works with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and Home Assistant via Matter, and with the eWeLink app. MINI ONE also suits users of open-source platforms through its local API and MQTT.

Good to know: Both versions need a neutral wire and must be installed by a qualified electrician. A wall box depth of 60 mm is recommended; they fit EU round boxes and 86/120-type boxes. They use 2.4 GHz Wi-Fi only. On MINI ONE the two "L Out" terminals are the same single output (both loads switch together); it is a 1-channel device. MINI DUO's 16A limit is the total for both channels.
