If you run script/setup from the root of the checked out project it will set up a venv for you and also install a commit hook w/ pre-commit so that you can catch the lint errors before committing. if you already have a venv activate it and run pre-commit install

Pre-commit fixes are now also applied automatically as well when pushed to a PR. So, you can just update your local changes from the branch you pushed to.
Still, I'd also recommend running script/setup. The path should be updated for uv after the install, but I remember there being issues with the install script not doing that in the past, so let me know if you need any help with it.

FYI, we merged an initial quirk that defines the custom cluster and attributes: zigpy/zha-device-handlers#3346
No quirks v2 entities are exposed yet. I'm hoping we can get a custom attribute_converter for parsing state exposed via quirks v2 soon: #305. If that's done, we might be able to fully expose everything via quirks v2 for this device.
