The SONOFF MINI-ZBRBS is an ultra-compact Zigbee smart module for controlling roller shutters and curtains, designed to fit into standard wall mounting boxes. With this device, a traditional motorized shutter or curtain system can be easily upgraded to a smart home solution without replacing the entire setup. Compatible with motors up to 1A load, it works with most small and medium-sized home roller shutters, blinds, and curtain systems.

When connected to a Zigbee hub, it enables remote control via app, scheduling, and integration into smart scenes. Additionally, the module functions as a Zigbee signal repeater, helping to strengthen and expand your Zigbee network. This not only makes shutter control more reliable but also improves the stability of the entire network. The MINI-ZBRBS supports multiple shading solutions, including curtains, shutters, awnings, and even projector screens. With its calibration function, roller shutters and blinds can be controlled with percentage precision, allowing optimized light and temperature control.

• Compact size – fits into smaller wall boxes, including standard European 80 mm boxes.
• Precise percentage position control – set shutters and curtains to partial positions for improved comfort and energy efficiency.
• Scheduled operation – automate opening/closing at predefined times.
