SONOFF Mini-ZBRBS is a miniature switch for blinds and roller shutters that delivers smooth and precise position control thanks to Zigbee 3.0. It supports a wide range of AC motors (4/5 wires) and easily fits standard 60 mm junction boxes. With local scenes, automation continues to work even during internet outages.
The device enables percentage adjustment (e.g., 47% or 79%), automatic travel range calibration, and works with HOME ASSISTANT for advanced scenarios.
