I'm guessing I know the answer to this based on what happened, just trying to confirm and maybe prevent someone else from running into this issue. Seems I can't create automations without an Apple TV or HomePod now. I thought it was entirely optional based on https://support.apple.com/en-us/HT213481 . Seems if you create a new "Home" on 16.4, it automatically updates to the new architecture.
I was trying out 'HomeBridge' the other day getting some non-HomeKit devices to work with HomeKit. I already had iPadOS 16.3 working with an existing HomeKit outlet, then added HomeBridge and some other devices to the existing home. I updated to 16.4, and tried to get another family into the "Home", their device said I needed to update my software. Since I have no Apple TV or HomePod I declined updating. I got rid of HomeBridge since I couldn't really share at this point, old devices were still showing in my "Home" this morning. I then deleted the whole Home to start over fresh. I tried this morning to recreate my timer automations for my lamp that worked under 16.3 only to have the above issue.
Never once did I complete the "upgrade" instructions, no one else in my house would even have access or the slightest idea how to do it. 'Use iPad as a Home Hub' not available in Settings anymore.
Not trying to make people feel sorry for me, I'm a big boy, I can deal with it! Just maybe it will help someone else.
