The SONOFF Fusion Series Orb‑ZBRBS is a Zigbee smart roller shutter wall switch that transforms traditional electric blinds, curtains, or motorized shades into remotely controllable devices. At its core, it features the well-known Mini-ZBRBS module. The switch connects to a compatible Zigbee hub via the Zigbee 3.0 protocol, enabling control through mobile app, automation routines, or voice assistants. This allows you to conveniently manage the position of your blinds, schedule opening/closing, and integrate them into your smart home system.
The Orb‑ZBRBS enables precise percentage-based position control (e.g. 25%, 50%, or 80%), supports daily schedules and scenes, and enhances Zigbee network stability with its signal repeater (router) function. Its modern, white, flush-mounted design fits most European wall boxes and interiors. With the optional frame accessory, it can be neatly grouped with existing switches. It’s important to note that the maximum supported load is 1 ampere – it is not suitable for larger motors over 30 Nm.
