HomeKit Troubles

Update 1 • November 30, 2019

One of the details I had left out but felt wasn't necessary was tvOS 13's support for multiple users. My Mom has an Apple TV 4 in the other room (also Model A1625).

I had a thought earlier today thinking maybe having my login on that device, it could be causing some interference. So I decided to check, I went to the Apple TV in the other room and found out that I was the selected user. I don't remember when I did that but I switched to my Mom's account and went back to my room to find out that I had some control over the HomeKit stuff again, although the configuration got very confused, if that's a word I can use.

Long story short, by logging out of that Apple TV and keeping my account to just my machine, I was able to get my Apple TV working with HomeKit again, although I ended up having to reset the configuration anyway. Therefore, I consider this thread not completely solved, as I want to see what things will be like in a few days. I'll keep everyone posted.

No luck. I did this just by signing out of iCloud on my Apple TV and restarting, as well as doing this and toggling Home off of iCloud on my iOS devices and restarting them like you instructed. Neither have allowed me to use the Home app or control my accessories still.

Update 2 • December 7, 2019

After about a week of observation, it seems that the fix was removing myself from someone else's Apple TV.

Specifically, within iOS 13, iPadOS 13, and tvOS 13, you can add yourself to your Apple TV 4, HD, or 4K by using a compatible device with it. This will properly add your account to the Apple TV to be a user there, as well as make a tile of it visible in the Home app.

Now, everything in our configuration is on my account, as I run the entire HomeKit setup, except for my Mom's Apple TV, which is under her account login. I can add myself to that Apple TV, but my guess is that it creates confusion if I choose myself as the user on that Apple TV. I can't really prove or deny this being the case, but this was the first time since this problem started that something worked.

A side-effect of this whole thing seems to be that making edits on HomeKit accessory names or scenes, as well as adding new scenes tend to delete themselves shortly after making them, although this only happens occasionally. I see this more on my iPhone than my iPad, but this isn't the end of the world, so long as I have control still.

I attempted this but it did not fix the problem. I did this on both my iPhone and iPad. Should I also disable anything on my Apple TV, like iCloud and restart it too?

I hope so too, I appreciate your help though.
