Yes, there have been changes to Home Assistant to detect this. Many third party integrations suffer from it. Your post is off topic here.

[gregeeh]

I'm getting the same error. Why it is off topic?

[tomlut]

Because it had nothing to do with this bureau_of_meteorology integration. It was for a completely different integration. You report the warning (not error) in the github repository that caused it, not a completely unrelated one.

[gregeeh]

Thanks for your quick reply.

I'm really sorry but I don't understand your comment "it had nothing to do with this bureau_of_meteorology Integration" when the error states "please create a bug report at https://github.com/bremor/bureau_of_meteorology/issues"

[tomlut]

Sorry I thought you were the other person who's comment has since been deleted.

This identical error also just started occurring in another custom integration that I use.

Conversation in this issue may privide clues; [BJReplay/ha-solcast-solar#14](https://github.com/BJReplay/ha-solcast-solar/issues/14)

As you can see, they had an issue with the solcast not BoM integration.

[gregeeh]

OK, thanks for the explanation.

Fix by release 1.3.2. Thanks @dbiczo
