Description
The SONOFF MINI DUO-L (MINI-ZB2GS-L) is a compact 2-gang Zigbee 3.0 smart switch from the SONOFF MINI Extreme series that needs no neutral wire. It suits single-wire setups in older apartments and installs without circuit modifications, controlling two independent channels at 8A each, up to 12A in total (resistive load).
Its space-saving design fits tight wall junction boxes, including the European-standard 60 box, and keeps your existing wall switches for manual and two-way control. Control the lights from the app or by voice, set timers, or integrate the switch with open-source platforms such as Home Assistant (ZHA / Zigbee2MQTT).
Note: a Zigbee gateway is required (see "Works With" below). Minimum load: 3W.
