SONOFF MINI-ZB2GSL-E is a ZigBee 3.0 two-channel wall switch designed for electrical installations without a neutral wire. It allows independent control of two lighting circuits, making it ideal for upgrading older wiring without additional modifications. The switch supports smart scenes, schedules and timers through compatible smart home systems. With ZigBee Binding, it can communicate directly with other ZigBee devices for fast local control even without internet access. The compact flush-mount design fits standard EU wall boxes and blends easily into modern interiors. A fire-resistant housing and durable relay ensure reliable operation and long service life.
