Add Awair Local API support

[zachberger]

Proposed change

Add support for Awair's (beta) Local API. This API supports more frequent polling and will work when there is no Internet connection.

Previous attempt in #39538 but that was introducing an entirely new integration. #39538#issuecomment-693547702 suggested extending the current awair component to add an option for the local API, which this new PR does. #39538 also suggested mDNS discovery, that is not in this PR, but could be explored and submitted in a future PR.

Still to be done:

• More tests need to be written
• more thoughtful unique IDs for local API
• more thoughtful strings for ConfigFlow

Type of change

• Dependency upgrade
• Bugfix (non-breaking change which fixes an issue)
• New integration (thank you!)
• New feature (which adds functionality to an existing integration)
• Deprecation (breaking change to happen in the future)
• Breaking change (fix/feature causing existing functionality to break)
• Code quality improvements to existing code or addition of tests

Hey there @ahayworth, @danielsjf, mind taking a look at this pull request as it has been labeled with an integration (awair) you are listed as a code owner for? Thanks!

🎉 🎉

Yes, I think this is the right approach. I keep thinking "gosh, we should really come back to the local api" but I've had approximately zero time/drive to do so. Thank you so much for taking up the charge!

I will reserve thorough review until it's marked as ready, but I do think the overall direction at the moment is correct.

Regarding mDNS discovery: yes, that can come later. In the future, I think we should have a flow that prefers local by default (and does mDNS discovery for you) but accepts an API token to still support the oldest generation devices. But like you proposed: we'll do that next. A list of hosts is a good next step and we need momentum to keep going. This gives us that momentum!

Thank you! Excited to review it when it's done! 😄

Slowly making some progress on this. Its summer so not too much free time.

• I was able to get discover working fairly simply in 5d4efb2
• Started working on documentation in Add information about Awair Local API home-assistant.io#23588

I have more tests to add before this is done, but @ahayworth could you PTAL too, I'd appreciate your feedback on the state of the integration.

Great contribution, thanks! 🎉

[ahayworth]

@zachberger I think it's lovely. 😄 If you want to help maintain this component ... that's lovely too 😉 I don't have as much time for open source right now as I would like, and I don't want to be a blocker for further improvements!

Thanks everyone for the help getting this across the line!
