I'm also seeing the similar issue. This is continuously logging once every 10 seconds. Please let me know if anyone need more information to debug this issue. Thanks!

From what I understand, AppDaemon addons are not supported.

So, reproduce standalone and then report it here.

Hi @hacscred

sorry, im not sure I quite understand (probably because im just a user of AD). I'm currently using AD as an Addon in Home Assistant, and its a supported addon.

Not sure how I can use it as a standalone, you mean in docker for example?

thanks

[hacscred]

It's my understanding that Home Assistant creates a particular run-time environment, which complicates matters.

Unless the specific installation instructions are followed from the documentation by the user, I think it's a waste of time for the developers of AD.

They might feel different, but I seen to recall other issues fir which that was the case.

You aren't even saying which version of AD you are using underneath the Home Assistant configuration.

A useful bug report would generate a valid MQTT message and it would call a particular logger or it would just call the logger with a valid input. I haven't seen you prove that logging is supposed to work for the value you provided by referencing the documentation. As such all you have right now is a claim that something is wrong.

You might argue that programs should never exit (which you didn't) and you would be right, but I think that level of engineering is not done in this project not in many other Python projects.

still happening in my logs.
