HomeKit

HomeKit at one Home has failed. No response from MeRoss devices. No response from ECOBEE. No response from Lutron switch. All were working until this morning. I cans all devices through the Netgear log-in. MeRoss App and ECOBEE app work to control their devices. Other Home still working.

Tries restarting router several tines. Restarted iPhone 11P and updated to 16.0.2 this morning. Restarted Apple TV4K a couple of times.

If the only answer is to completely rebuild the Home with all three manufacturers devices removed and then laboriously re=created, then HomeKit is totally lame. But this stuff worked most of the time for the last year.

Why can't Apple provide some kind of solution ??

P.S. There is no category for HomeKit. Sorry
