The Sonoff MINI-ZBRBS is a compact Zigbee smart switch designed to automate the operation of roller shutters, blinds, and curtains. By utilizing the Zigbee 3.0 protocol, it integrates seamlessly into your smart home ecosystem via compatible hubs from Sonoff, Aqara, or Tuya, allowing you to manage your window coverings through the eWeLink app or via voice commands with Alexa, Google Home, and SmartThings. This device supports a supply voltage of 100-240V AC and can handle a maximum power of 480W at 240V, ensuring it can drive most standard motorized blinds. Its small polycarbonate housing, measuring roughly 39.5 x 39.5 x 18 mm and weighing only 25.1 g, allows it to be tucked away inside a wall box for a clean installation. To ensure precise control, the switch features a positioning range from 0% to 100% with both automatic and manual calibration options, so you can set your blinds to a specific height. Built for indoor use, the unit operates reliably in temperatures ranging from -10°C to 40°C and includes built-in overload protection for added safety. It is a practical choice for anyone looking to synchronize their home lighting and shading, providing a low-power solution for remote or scheduled window management.
