This is what broke the previous test instructions ZHA as an external library by puddly · Pull Request #120190 · home-assistant/core · GitHub

Which means the changes need to be made in zigpy/zha

You or he need to apply this patch to zigpy-zboss to update:

The user-friendly question is discussed here:

And a directly related question posted to zigpy-zboss developer here:

There is more info and back-story related to all above here:

Hi!

My friend helped me compile the ZBoss NCP sample for the Nice!Nano v2 (nRF52840).

Thought i’d mention it here since nice!nano clones can be found very cheap on alix (2 for ~$6).

FYI, it seems like puddly has now begun working on a new experimental feature to make it easier for developers and testers to try external radio types in Home Assistant’s ZHA integration without needing to manaully install or modify code in HA’s container. See:

Note! He specifically mentions that it is a fundamentally a development tool to allow for testing pre-alpha radio libraries for zigpy, (like Ziggurat, ZBOSS, BLZ, or ESPZB), so users should not use it in any production enviroment, and do expect breakage if rely on it.
