Sonoff MINI ONE Zigbee (MINI-ZB1GS) smart relay switch, 16A, 1 channel, Zigbee 3.0
Description
Sonoff MINI ONE Zigbee (MINI-ZB1GS) – 16A single-channel smart relay for in-wall boxes
The Sonoff MINI ONE Zigbee belongs to the MINI Extreme Gen5 series and turns a conventional switch into a smart one: it is installed in the wall box behind the existing switch and controls a circuit of up to 16A / 3840W. It has smart overheat protection with an internal temperature sensor and acts as a Zigbee router, extending the network in your home.
Note: the relay requires a compatible SONOFF Zigbee hub, for example SONOFF Bridge-M, ZBBridge-U or iHost. For basic settings it also offers Proximity Mode, a direct link to the phone without a gateway. The relay requires a neutral wire. A 60 mm deep wall box is recommended; it fits EU, type 86 and type 120 boxes. Indoor use only. Installation must be carried out only by a qualified electrician.
Features:
- Maximum load 16A / 3840W, at 100-240V~
- Smart overheat protection with internal temperature sensor
- Zigbee Binding: direct local control with wireless switches or sensors (for example SNZB-01M), without a gateway after the initial setup in Home Assistant
- Zigbee router: default range to the gateway of 180 m, up to 250 m with Turbo mode
- Detach Relay, multiple switching modes and Delay Power-on
- Timer, scenes and voice control
- Proximity Mode for basic settings directly from the phone
- Works with eWeLink, Amazon Alexa, Google (voice control via eWeLink), SmartThings, Apple Home (via Matter Bridge) and Home Assistant (Zigbee2MQTT 2.12.1 or newer)
Practical use cases:
- Hallway light: the wall switch keeps working, and the light can also be turned on from the app or by voice.
- Wireless button without a gateway: through Zigbee Binding, a SONOFF SNZB-01M button turns the light on directly, even if the gateway is unavailable.
- Bathroom fan: the timer switches it off automatically after a set time.
- Large home: every MINI ONE installed strengthens the Zigbee network for sensors located further from the gateway.
