I have tested this on my air conditioner with the following scenarios and results:

  • Expected: A new entity called "Air UV Nano" is created.

• Scenario: Turn on from Home Assistant

All scenarios have passed successfully.

Since this is my first time creating or contributing to a custom component, I would greatly appreciate a code review or any suggestions to further improve this pull request.

Thanks for this PR, but seems that some checks are missing:

• you should check that device support this feature, I think that not all LG AC device have UV Mode
• you should check that device is in valid status to enable this mode (e.g. probably does not mae sense enable this mode when AC is off)

Take a look to Jet Mode implementation to understand what I mean.
