Actually, a system CAN be registered remotely, manually, if you are working with your registered dealer (which you can also change). It is all managed at customer.control4.com under "My Account - My System" and "My Account - Smart Home Pro". A dealer using Composer pro can register a system using the code that an unregistered controller will display under "My System", and then, if you allow, remotely connect to your system to help. I've had MANY issues with the Certified Apple TV HomeBridge Driver, but after a couple years with it, I learned that the MAIN issue is that at least ONE AppleTV needs to be hardwired. With the Halo Remote, I've been revisiting the setup a lot (but on other installs, I still prefer Jesse Smiths IR driver for Gen3+ AppleTV, as it has all the extra buttons and press-n-hold options missing from the C4 IR driver). Basically, to make the Home bridge driver work, you need an iphone or ipad with the latest iOS, all appletvs updated as well. Use that device to login to all the appletvs with bluetooth (if you have problems with existing appletv, log out the primary user and log back in with "using my device" option. THEN setup homekit in the C4 app. Disable and re-enable appletv control if you've previously tried and had problems. After this is done, select each appletv in composer, and it has been working reliably, with voice control even, on the 20-30 halo remotes I have installed so far. Haven't had a callback, yet (knocks on wood).
