Seeing similar issue.

I could be wrong, but it looks like the add-on is detecting both of my adapters (SkyConnect and ZWA-2) and then trying to use the ZWA-2, and failing. Restoring backed-up version 2.6.3 restores functionality for now.

[Nerivec]

@tabula-raza looks like the added detection for the ZBT-2 also ends up conflicting with the ZWA-2. Be sure to provide an explicit path in your configuration, so it does not rely on auto detection.

@Krzysztonek we have a fix pending in dev/edge that should take care of I/O issues with 2.7.0. A hotfix will be released, you can try edge in the meantime: https://www.zigbee2mqtt.io/advanced/more/switch-to-dev-branch.html#home-assistant-addon
The first log shows the port was misconfigured though, so, would be different than LOG2.

[tabula-raza]

@Nerivec yes. I did some investigating and my best guess is that the problem is in how the fingerprint match loop in adapterDiscovery.ts is constructed, resulting in the loop exiting early with a false positive.

Full disclosure: after looking at the recent changes to zigbee-herdsman on github, I cloned the repo locally and used cursor to try to understand the script better including providing the log snippets. it suggested that the loop is going in alphabetical order of ports, and exits on first match, rather than highest match across all ports (according to the AI, the ZWA-2 should be scored 2, while the SkyConnect should be scored 4, but the script doesn't get that far.) It recommended a change in the code, but submitting a PR based on that felt presumptuous.

Hope this is helpful!

[tabula-raza]

And yes, specifying the path in the configuration.yaml for the add-on as described here worked. Thanks!

[Krzysztonek]

The first log shows the port was misconfigured though, so, would be different than LOG2.

Hi @Nerivec,

Both LOGs were taken from different days, so they differ significantly.
At the time being Z2M addon starts, then works normally for couple of minutes, and then it goes down, then restarts automatically again. Recurrent Up and Down.
I will install Edge for temporary usage, awaiting the fixed Normal stable version.

Thank you so much for taking care of such an issue 💟

[Nerivec]

@tabula-raza yes Koenkk/zigbee-herdsman#1578 should fix it. I used your sample logs to add a reference test for it 😉

Unfortunately, Z2M still does not start in my system after updating. No issues with other add-ons so far.
Z2M add-on version: 2.7.1-1
Core: 2025.12.1
Supervisor: 2025.12.2
Operating system: 16.3

Z2M Log after loading attempt:

Any suggestion what is going on here?

[Nerivec]

@TMV-NL this is unlikely to be the same issue. From what I can see, that error in deconz would point to the adapter not responding at all on start. Did you check the port is still the same, unplug/replug, reboot entire machine, etc.?
If you can't find anything wrong, open up a new issue: https://github.com/Koenkk/zigbee2mqtt/issues/new?template=problem_report.yaml

[TMV-NL]

I tried the reboot before, not after the update. Will check port config.
Is it possible that the adapter is broken?

[Nerivec]

Is it possible that the adapter is broken?

It's always possible, but more likely that it's a config issue / bug somewhere.

[TMV-NL]

It appeared Deconz add-on was not running. I rebooted the machine and now it is. But Z2M still won't run. I cannot find anything worng with the Deconz config.

The Deconz log:

It still seems to give an error on the adapter connection though. The Deconz add-on works fine now.

Any suggestion?

[Nerivec]

What deconz add-on are you talking about? Z2M works alone, if something else is using the adapter, then Z2M can't use it.
