Can you solve this. (HAOS 12.4)

I'm seeing similar errors, running HA 2024.7.0.

I obtained the same (verbatim as far as I can tell) warnings as @jkfranks9 on:
Core: 2024.7.1
Supervisor: 2024.06.2
Operating System: 12.4
Frontend: 20240705.0

Edit:
Looks like this may be similar to #608 and #609

[craigbarratt]

The sunrise/sunset issue should be fixed by @IgnusG's PR #610, which has been applied. It would be great if someone could test github main to confirm the fix.

[jkfranks9]

Not a github expert, so I may not have done this correctly. But I copied the 2 files in #610 (manifest.json, trigger.py ... ignoring test stuff). I rebooted and see the same problem noted in this issue. If by "sunrise/sunset issue" you mean #608, I never saw that problem.

[IgnusG]

If by "sunrise/sunset issue" you mean #608, I never saw that problem.

@jkfranks9 I think #608 only occurs if you use something like @time_trigger('once(sunrise)') somewhere in your pyscript files. The original issue description of #612 refers to the same issue as #609 and #608.

The issue you saw in #612 (comment) occurs in a different situation (not caused by time based triggers like the sunrise/sunset issue). I did not fix that in my PR - it should however be fixed by @craigbarratt in the latest master branch so you can try that one out maybe 👀

These blocking call warnings can occur from anywhere within homeassistant integrations (they are not exclusive to pyscript) and they can be caused by different things (even by different functionalities pyscript offers).
Home assistant tries to help here by identifying them as they can result in poor user experience if not fixed - but the way to fix them can be different depending on where they occur

[jkfranks9]

Thanks, so I believe I should open a new issue for the problem I mentioned in comment 2. Will do that when I get a chance.

Please first try to deploy master to see if the problem still occurs, otherwise yes it would be best to open a new GitHub issue for it 🙏

If you use sunrise/sunset and you don't see any warnings for those, this issue as well as #608 can be closed

[jkfranks9]

I pulled in the master branch, and I no longer see the blocking problem. Thanks.

The same messages related to os.walk() and os.scandir() appear even 'config/pyscript' folder is empty.

Hey @craigbarratt 👋 Could you create a new release for the latest changes?
