The SONOFF MINI-ZBDIM is an ultra-compact, in-wall Zigbee 3.0 trailing-edge dimmer that allows you to upgrade existing lighting circuits into smart ones easily and cleanly. It offers smooth, flicker-free dimming with precise percentage control and soft fade transitions. Additionally, it acts as a Zigbee router, strengthening your mesh network for increased range and stability.
Designed in the Mini Extreme form factor, the module fits comfortably behind standard wall switches and retains traditional control – supporting both momentary (push-button) and toggle switches, selectable directly on the device. Advanced settings such as minimum brightness threshold, transition time, and calibration allow fine-tuning for compatibility with various dimmable LEDs, bulbs, or electronic transformers.
Thanks to its Zigbee-based control, the MINI-ZBDIM integrates into brand-agnostic smart homes: compatible with Home Assistant (ZHA / Zigbee2MQTT), SONOFF gateways (e.g., NSPanel Pro, iHost), and other Zigbee 3.0 hubs. Remote control, dimming, scheduling, scenes, and automations are fully supported – even via voice assistants, depending on the platform used.
