I'm going to do a bit more cleanup

Nice. Can we do this via the device registry and pull the manufacturer/model as it is stored rather than trying to reconsitute it with .title()? Would be able to get the firmware version that way as well?

I was thinking about doing that in a followup when I find the need to use the device registry for something else. This one was easy since we already get the entity registry. I did a bit of testing with the firmware and HomeKit has strong requirements on the formatting of the versioning so I don't think it is possible.

Converting to draft since this is going to cause a conflict with #35238 and I don't want to discourage contributions because of conflicts.

@Jc2k I did some more testing with this and was able to get your device registry suggestion implemented.

Nice one!

Going to have to resquash to cleanup the conflict mess
