I agree about the Bluetooth. The Door lock is the only Bluetooth device we have for good reason, but I am unaware of any other way for wireless door locks to work with Apple Home at present.
In the Home app, you can see which device is the acting (connected) Home Hub, and which are on standby. I was able to disconnect the Apple TV’s. But since the HomePods don’t have an option for such setting, it appears the last one to boot attempts to take on the responsibility of being the Hub.
And when our Foyer located Pod is the one connected, while the other 3 are in standby, the lock remains reliably accessible.
For this reason, for now, I think I’ll purchase some WiFi plugins to toggle power on my HomePods. Maybe I won’t have to run up and down stairs to power cycle them to keep the Foyer Pod as the connected Hub.
I just wish Apple would consider setting up 3-4 story 10,000 sqft. home for testing and development. But My guess is that since the majority of investors in this technology, while in its infancy, do not have homes that large and spread out, it’s currently impractical from a financial perspective, even though they are a trillion dollar company.
The most discouraging thing is that there is not a dedicated support mechfor Apple Home...
I bet if Jobs were still with us, things would be a little further along...
