Sonoff MINI-ZB2GS two-channel smart switch, Zigbee 3.0
Delivery options to:
Choose countryThe Sonoff MINI-ZB2GS is a compact Zigbee 3.0 smart switch module for independently controlling two lighting circuits or devices. It also acts as a Zigbee router to extend network coverage.
Control and automation
Use physical switches, app control, schedules and smart scenes through eWeLink or Home Assistant via ZHA or Zigbee2MQTT.
- Switch compatibility: supports bistable, monostable and SPDT switches.
- Detach Relay: separates physical switch operation from power switching, allowing smart bulb scenes to be triggered without cutting power to the bulbs.
- Power restoration: choose the last state, on or off when power returns.
Load and installation
For resistive loads, the limit is 10 A per channel and 16 A total. The 45 × 39.4 × 16.8 mm module fits type 86, EU and 120 flush-mounted boxes with a minimum depth of 60 mm. It has a flame-retardant PC enclosure, overheat protection and surge protection.
A separately sold Zigbee hub is required, including for Detach Relay. Motion-triggered scenes also require a separately sold Zigbee motion sensor, such as SNZB-03P. The package includes the switch module and a user manual.

Is a Zigbee hub included?
No. The package contains the Sonoff MINI-ZB2GS and a user manual. The Zigbee hub required for operation is sold separately.
Can it control smart bulbs without cutting their power?
Yes. Detach Relay separates the physical switch from power switching, allowing it to trigger scenes on Zigbee smart bulbs while keeping them powered. This function requires a Zigbee hub.
