Sonoff MINI-ZBRBS Smart Switch ZigBee Compatible Mini Size for In-Wall Installation, Flat Relay

The Sonoff MINI-ZBRBS is a compact Zigbee 3.0 mini switch for in-wall installation that converts standard roller-shade and blind systems into smart, controllable devices. It fits into typical wall boxes and supports local control, percentage positioning, calibration of motor travel, and integration with popular automation platforms such as Home Assistant. The module also functions as a Zigbee router to strengthen the mesh network and works with a wide range of tubular and chain motors designed for AC 4-wire and 5-wire installations.

Advantages

Small dimensions allow installation inside standard 60 mm diameter boxes while providing precise percentage-based position control and automatic calibration of the motor range. The device supports local Zigbee scenes and continues to operate without internet access, and it also acts as a signal repeater to improve network stability. Compatibility with conventional wall switches preserves manual control alongside smart operation.

Suitable for

• Automating roller shutters and roller blinds
• Converting wired tubular or chain motors to Zigbee control
• Integration into Home Assistant and similar Zigbee hubs
• Installations requiring a compact in-wall module in standard switch boxes

How to use

Install the MINI-ZBRBS inside a standard wall box behind the existing switch or in the ceiling cavity near the roller motor, following local electrical codes. Connect supply lines, neutral and motor wires according to the motor type (4- or 5-wire AC connections) and the provided wiring diagram in the user manual. Pair the module with a Zigbee hub (for example, Home Assistant with a Zigbee coordinator) to enable remote control, percentage positioning and scene logic. After initial wiring, run the calibration procedure so the module learns the motor travel limits for accurate position control.

Recommendations

Use the device with compatible tubular or chain motors rated within the specified voltage and current limits. Ensure correct wiring and grounding during installation and perform calibration after installation. For stable Zigbee coverage, place the module within an existing Zigbee mesh or add additional routers if needed. Refer to the included user manual for pairing, wiring diagrams and safety instructions.
