SONOFF Fusion Series Orb‑ZBRBS is a smart Zigbee blind/curtain wall switch that turns traditional electric blinds, curtains or motorized blinds into remote controls. Inside the switch, the already well-known Mini-ZBRBS has played a major role. The device is connected to a compatible Zigbee hub via the Zigbee 3.0 protocol, so it can be controlled from a mobile application, with the help of automations or voice control. With this, you can conveniently control the position of the blinds, time the opening/closing and integrate it into your smart home system.

Orb‑ZBRBS enables precise percentage position adjustment (e.g. 25%, 50% or 80%), supports daily schedules and scenes, and increases the stability of the Zigbee network with its signal repeater (router) function. The modern, white, recessed design fits harmoniously into most European wall boxes and home furnishings. And with the available sorting frame, you can easily organize them with the ones you already have.

It is important that the maximum load capacity of the switch is 1 ampere, so larger motors (shutter doors, larger awnings), typically over 30 nm, can no longer be used with it.
