SONOFF Zigbee Dimmer Switch | MINI-ZBDIM

The Sonoff MINI-ZBDIM (MINI Extreme series) is a flush-mounted Zigbee 3.0 dimmer (trailing-edge) that adds stepless dimming, scheduling, and automation capabilities to conventional lighting circuits. It supports external switches/push buttons and provides additional power consumption data (power detection).

Highlights

• Zigbee 3.0 (IEEE 802.15.4)
• Dimmer for dimmable LEDs, halogen, incandescent bulbs, as well as dimmable electronic transformers
• External switch/push button at input S1/S2 (rocker / push button; switching via device button)
• Brightness calibration (auto-calibration via button press or via app)
• Power detection: Consumption/power data can be used in home automations
• Over-temperature protection
• Functions as a Zigbee router for range extension in the mesh network
• Compact design for flush-mounted/junction boxes

Home Assistant

Usable in Home Assistant via Zigbee (e.g., ZHA or Zigbee2MQTT) – dimming, on/off, automations, and evaluation of power/consumption data. Via Home Assistant, the MINI-ZBDIM can also be integrated into automations together with devices of other technologies (e.g., Wi-Fi, Matter, Thread, Z-Wave).
