SONOFF MINI-ZBRB | Zigbee Roller Shutter Relay Module

Do you already have a motorized roller shutter or curtain system with a wired, manual wall switch? The SONOFF MINI-ZBRBS is designed precisely for that type of installation. This compact Zigbee flush-mounted module makes an existing AC roller shutter or curtain motor smart, without needing to replace the motor itself.

What system is this module suitable for?

The MINI-ZBRBS is intended for existing motorized roller shutter and curtain systems with traditional wiring. It works with general 4-wire and 5-wire AC motors and supports an existing mechanical wall switch, allowing for both manual and smart control.

• Suitable for existing motorized roller shutters or curtains with AC motors
• Suitable for installations with a wired wall switch
• Not intended for manual roller shutters without a motor
• Not intended as a standalone wireless remote control without an existing wired installation

Power supply and connectivity

The module operates on 100-240V AC, 50/60Hz and supports motors up to a maximum load of 1A. Communication is via Zigbee 3.0, and the module also functions as a Zigbee router, making your mesh network stronger and more stable.

Functionality and control

Through the eWeLink app, you can remotely control your roller shutter or curtain and precisely set opening percentages. You can also create schedules and smart scenes, while the existing mechanical wall switch remains usable for manual control.

The built-in calibration function helps to determine the roller shutter's position more accurately. This ensures more consistent percentage control, even when the motor's run time is not entirely uniform due to mechanical tolerance.

Installation and mounting

The MINI-ZBRBS is designed for installation in a standard EU flush-mounted box behind an existing switch. The manufacturer states that no extensive modifications are needed if you already have a compatible motorized installation with a mechanical switch.

⚠️ This is a wired flush-mounted module for 230V installations. Installation should only be performed when the power supply is completely switched off, and if in doubt, by a qualified installer.

Home Assistant

The MINI-ZBRBS works with Home Assistant via ZHA and Zigbee2MQTT. After pairing, you get control for opening, closing, stopping, and position control, depending on your configuration and calibration.

• Put the Zigbee coordinator in pairing mode
• Power the module and activate pairing via the button on the module
• Add the device in ZHA or Zigbee2MQTT
• Check the motor's rotation direction and adjust the wiring if open/close works in reverse
• Then calibrate the run time for accurate percentage control

Control works locally via your Zigbee network. This is particularly interesting for users who want to build a local smart home without relying on cloud automations.

Homey

The MINI-ZBRBS is visible within the SONOFF ecosystem on Homey, but the practical experience with advanced functions may vary per setup. Especially for calibration and specific motor configurations, it is advisable to check compatibility in advance within the Homey community.

Other platforms

Through a compatible Zigbee hub, control is also possible with Amazon Alexa and Google Assistant. A Zigbee gateway is still required for these integrations; the MINI-ZBRBS does not work independently without a hub.

Automation examples

• Automatically open the roller shutter every weekday at 07:00 and close it at 22:30
• Automatically close the roller shutter to 40 percent when the outdoor temperature exceeds 27°C and the sun is on the facade, followed by a push notification in Home Assistant

Points of attention

• Only suitable for existing motorized roller shutter or curtain systems
• Only suitable for compatible 4-wire or 5-wire AC motors
• Only intended for installations with existing wired control or motor wiring
• Not suitable for manual roller shutters without a motor
• Not suitable for motors above 1A load

Frequently Asked Questions

Does this module work with every roller shutter?

No, only with existing motorized roller shutter or curtain systems with a compatible AC motor and existing wiring.

Can I use this for a manual roller shutter?

No, without a motor and wired installation, the MINI-ZBRBS is not applicable.

Do I need an existing wall switch?

The module is intended for installations with existing wired control or motor wiring. Support for traditional mechanical wall control is precisely one of the core functions of this model.

Do I need to replace my motor?

No, quite the opposite. This module is intended to make an existing compatible motor smart without replacing the motor itself.

Do I need a hub?

Yes, for smart control you need a Zigbee 3.0 hub or coordinator, such as a setup with Home Assistant.

Does this work locally in Home Assistant?

Yes, local control is possible via ZHA or Zigbee2MQTT. This makes this module interesting for those who want to automate roller shutters locally without dependence on external cloud logic.
