Review: SONOFF ZBMINIR2 - Control your devices and extend your Zigbee range!

CNX Software recently reviewed the SONOFF ZBMINIR2, a mini Zigbee 3.0 smart switch that also functions as a Zigbee router. Here's a summary:

Design and Build: The ZBMINIR2 is noted for its compact size, 40% smaller than its predecessor, making it suitable for various switch boxes. It includes capabilities to enhance Zigbee signal strength with a 'Turbo Mode', which reportedly can reach up to 200m in open environments.
Functionality:
- It supports multiple external switch types (like SPDT, Rocker, Momentary) and can separate the relay state from the external switch operation, ensuring smart bulbs remain connected even when the physical switch is off.
- The device offers features like setting the power on state, delay power on, and inching (auto on/off settings).
Integration and Testing:
- The ZBMINIR2 was tested with both the eWeLink mobile app and Home Assistant using Zigbee2MQTT. It integrates well, providing access to all features available in eWeLink through Home Assistant.
- During testing, it was installed in real-world scenarios like table and floor lamps, demonstrating good performance as both a switch and a router without needing additional Zigbee repeaters.
Performance:
- The review highlights its reliability in maintaining connections, with improved LQI (Link Quality Indicator) values suggesting better packet transmission quality compared to its predecessor, the ZBMINI.
Software Features:
- New software capabilities like "Delay-On", "Detach Relay", and both Auto-On and Auto-Off inching make it versatile, akin to the WiFi-based MiniR4 but utilizing Zigbee.
Conclusion:
- The SONOFF ZBMINIR2 is deemed a decent choice for those looking to expand or start with a Zigbee-based smart home setup, offering robust functionality and integration flexibility with existing home automation systems.
