Collaborating on python-tado and reviving the Home Assistant Core migration

[msemelman]

Hi Erwin,

I hope you're doing well.

I'm a fellow Home Assistant user and I have several Tado Smart AC Control units running at home across multiple rooms. Over the past months, I’ve been running local forks and patches to work around the recent OAuth device auth hiccups, token refresh concurrency, and API rate limits. It’s been working reliably for my setup, but I’d really love to see these improvements landed upstream so everyone can benefit.

I saw the earlier work on HA Core PR #151933 and the reviewer feedback around splitting the migration into smaller, more digestible PRs (like freezing the test suite first, then auth/config flow, then coordinator/platforms). I'm also familiar with open PRs #189 and #190 on python-tado, which tackle very similar token locking and error mapping issues to what I patched locally.

I would love to offer some of my time to help move things forward, whether that is testing changes against my AC units at home (let me know if that hardware scope is enough, or if other device types are needed), or helping prepare the phased pull requests for Home Assistant Core. If having a co-maintainer on python-tado would be helpful to take some load off your plate, I'd be more than happy to do that, but my main goal is simply to lend a hand wherever it helps most.

Let me know what you think and how you'd prefer to collaborate!

Best,
Mariano (@msemelman)
