Are the code changes compulsory in this PR?
Or could they be a followup PR to the dependency bump?

[ggravlingen]

@epenet the changes to fan.py are required as the API in the dependecy has changed. The changes to the util functions are required too. Moving the error-handler to the util-file is not required though. I argued with myself if I was going to do that but since I was refactoring util functions it made sense to move that one too. Happy to put it back if it makes review easier.

I have been running this in my custom component. Apologies, I felt this PR became a bit sloppy when I moved the code into the core base. Will try to do better.

[MartinHjelmare]

Ok. Please test the code in the PR with a real device before we merge.
