Nixpkgs version

• Unstable (26.05)

Describe the bug

python-roborock requires home assistant 2026.3 which hasn't been updated yet. This causes vacuum entities to become unavailable, and thus unusable in home-assistant.

Currently home-assistant is at 2026.2.3, which specifies python-roborock==4.8.0

The latest version that seems to work from my testing testing is 4.15.0

After this a breaking change was introduced that causes home-assistant 2026.2.3 to fail to work, however this is fixed in 2026.3.0 where the package is updated to 4.17.1

I think this means we either need to override the home assistant package until it's updated, or downgrade python-roborock.

pyrate-limiter also appears to be required to be downgraded as the older versions require 3.x but nixpkgs now ships 4.x.

Steps to reproduce

1. Enable Home Assistant
2. Add the roborock component
3. In the Home Assistant UI add a vacuum
4. Check the logs and see the error, and that the vacuum is unavailable.

Expected behaviour

The vacuum should be available and no stack trace should appear.
