core: homekit_controller: unable to complete pair_setup with LG TV

Home Assistant release with the issue: 0.97.2

Operating environment (Hass.io/Docker/Windows/etc.): hassio stable x64

Component/platform: homekit_controller

Description of problem: My tv got the update for homekit support last week and I decided to finally try adding it to homekit but it fails to set up which then the tv generates a completely new pairing code. I finally got time to try and add it and keep the logs open.

Traceback (if applicable):

Agreed, it’s a shame neither of us were around when they were added to suggest that! That said, controlller is what Apple officially calls the consumer so I think it could be worse. Renaming would be hard at this point (too many users familiar with old names, and their configs would break if it changed), and we’ve tried to improve the docs. homekit_controller calls out the difference in the first paragraph of its docs. homekit has a callout right after the first paragraph. If you think you can improve the wording to be more noob friendly would definitely love to see a PR for that. But this is getting off topic - feel free to open a seperate ticket if you want to pursue this.
