zigpy-zboss library makes Nordic Semi nRF52840 Zigbee dongles compatible with Home Assistant

nRF52840 Home Assistant

zigpy-zboss is a Python library that adds support for Nordic Semiconductor nRF52840 modules to zigpy open-source Python Zigbee stack project, as well as other Network Co-Processor radios that run firmware based on ZBOSS Open Initiative (ZOI). This enables integration with compatible Zigbee gateway implementations such as Home Assistant’s ZHA integration component and allows users to directly control Zigbee devices from a wide range of manufacturers such as IKEA, Philips Hue, SmartSung SmartThings, ITEAD SONOFF, Xiaomi Aqara, and others. Home Assistant’s ZHA integration already worked with Zigbee dongles based on Silicon Labs Mighty Gecko EFR32MG21 or Texas Instruments CC2652P microcontrollers, but now it’s possible to use nRF52840 dongles and development as Zigbee Coordinators thanks to the zigpy-zboss library.   The zigpy-zboss ZBOSS radio library for zigpy source code and resources can be found on GitHub, but note that this is still an unofficial and experimental port, so testers need to manually […]
