I'll try to give this a second pass tomorrow after some sleep. I still need to look through the lib as well

[bdr99]

@bdraco Sounds good, thanks for all of your feedback so far!

[bdr99]

Updated this PR to add a brand for eufy, as suggested in home-assistant/brands#4039 (comment).

I think this is just about ready to merge. I found a few small presentation issues that need to be sorted out first

@bdraco Do you think the test failures are related to this PR?

[MartinHjelmare]

Please address the comments in a new PR. Thanks!

[MartinHjelmare]

Why are we using dict.get on line 50 if we know that they key is not missing?

[MartinHjelmare]

We could use self._attr_native_value instead in _handle_state_update and async_added_to_hass to set the native value.
