HomeKit Apple Home disappears from two Macs

[dmfresco]

I have a pretty elaborate HomeKit set up that until recently was working perfectly on our iOS and MacOS devices. All of a sudden, our home has disappeared from two Macs. One running the latest build of MacOS Ventura public beta. The running the latest build of macOS Monterey. I have tried toggling on and off Keychain. On this Mac, the new Home is discovering things but not in the configuration I have specified. Is there any way to get my well curated Apple Home, which is working fine on a Silicon MBP and the iOS devices in the house to work again on these two Macs? Is it a Keychain issue? I spent some time on the phone with Apple Support and they were recommending I wipe the whole computer!!!

That sounds extreme doing a reinstall. Did you try restarting them, the hub, and the modem/router?

It's possible the macOS Ventura beta is interfering with the setup. That happened to me when I was using iOS 16 beta, but not to this extent.

I am not sure it's a hub issue as the Home works fine on my iPhone and iPads, and my Silicon MBP. It's only misbehaving on the two Intel MBPs, one running Ventura Public Beta, the other running Monterey.
