Sonoff ZBMINIR2 - Ultra-Compact Extreme Zigbee Smart Micro Module

Presentation

The ultra-compact Zigbee micromodule that transforms any switch into a smart control.

The Sonoff ZBMINIR2, dubbed "MINI Extreme," revolutionizes home automation installation by offering the most compact Zigbee micromodule on the market (39.5 x 33 x 16.8 mm). Designed to integrate discreetly into European, Chinese 86, and American 120 electrical boxes, this ingenious module hides behind your existing switch to make it smart without altering the aesthetics of your installation. Thanks to its new-generation EFR32MG21 chip and "Turbo" mode, it extends communication range up to 200 meters in open space, which is 5 times more than the previous ZBMINI model. Beyond its smart switching function, the ZBMINIR2 plays a crucial role in your Zigbee network by acting as a router, capable of supporting up to 64 terminal devices to densify and stabilize your home automation mesh network. Compatible with a wide range of external switches (momentary, toggle, SPDT, door contacts), it adapts to all existing electrical configurations while offering advanced features like the "Detach" mode, specially designed to control connected bulbs without disconnecting them from the network.

Key functions

Ultra-compact format for universal installation With dimensions of only 39.5 x 33 x 16.8 mm and weighing 26.7 grams, the ZBMINIR2 easily fits into standard wall boxes, even the most cramped ones. It perfectly adapts to European round and rectangular boxes, Chinese type 86, and American type 120 formats, ensuring a successful installation in all architectural configurations. Its ergonomic design optimizes the available space within the box, facilitating wiring and allowing for the installation of multiple modules side by side if necessary. The V0 flame-retardant polycarbonate casing ensures maximum safety, while the CE, FCC, ISED, and RoHS certifications attest to compliance with the strictest international standards.

High-performance Zigbee router with Turbo mode The ZBMINIR2 doesn't just control your lighting: it becomes a crucial part of your Zigbee network by functioning as a permanent router. Thanks to the "Turbo" mode based on the EFR32MG21 chip, it achieves a communication range of 200 meters in open space, effectively eliminating dead zones in your home. Each module can relay signals to 64 Zigbee end devices, thus creating a robust and self-healing mesh network. This repeater function is particularly valuable in large homes or installations with numerous sensors and actuators, where the multiplication of routers ensures uniform coverage and unwavering reliability.

Total compatibility with existing switches and Detach mode The ZBMINIR2 seamlessly integrates with your existing wall switches thanks to its configurable "S" input. It supports momentary switches (push buttons), traditional toggle switches, SPDT, and even door contacts, offering unmatched installation flexibility. The "Detach" mode is a major innovation for smart bulb users: it maintains a constant power supply to the lamp even when the wall switch is in the "off" position, thus preventing the connected bulb from being disconnected from the network. The physical switch then becomes a simple scene button that sends commands to the home automation system without cutting the power, allowing you to retain manual control while preserving the smart features of your Zigbee bulbs.

Advanced automation and load protection Create sophisticated home automation scenarios by integrating the ZBMINIR2 into your smart ecosystem. Schedule operating times, create command groups to control multiple lights simultaneously, trigger lighting based on motion detectors or weather conditions. The power-on delay function protects your electrical equipment by avoiding the current surge that occurs when multiple loads turn on simultaneously after a power outage. Voice control naturally integrates via Amazon Alexa and Google Home once the module is paired with a compatible gateway, while group configuration makes managing entire areas of your home easy with a single command. The eWeLink app offers an intuitive interface to monitor the status of your switches and create custom automation rules.
