@viticci just saw the HomeKit hardware article on MacStories. Good read!
One note, the HomeKit API actually does support pan and tilt cameras officially. But manufacturers don’t support it as Apple Home doesn’t support it. And no third party supports it as no camera support it. 
See https://developer.apple.com/documentation/homekit/hmcamerasettingscontrol and all the tilt characteristics under it.
@aaron_pearce @viticci wait, you’re saying my HSV Tapo pan-and-tilt could have control in the home app right now?
@stephenrobles @viticci probably not in the official app as Apple is a bit slack supporting it all.
But if there was a camera that supported it, I would add it to HomeCam in an instant.
@stephenrobles @viticci It ends up being a catch-22 of sorts.
Apple not supporting it in their app, means no camera does, which means no third party app has the need to support it and it loops.
@aaron_pearce Oh wow, fascinating! Thanks. Will update.
