Downgrading HomeKit back to old architecture
Here's the answer to the question above I want to share with you. Even apple support didn't know this answer. After "upgrading" homekit, on some of your devices the Home app will not work. I found a solution in another forum, that I want to post here.
On you Ios device, got to : http://appldnld.apple.com/iOSProfiles/KeepLegacyHome.mobileconfig
- install the profile
- go to settings - HomeKit - rest
- press the red button, or choose "Reset configuration". (it will reset all of your Homes and you’ll need to do everything from scratch)
- Wait 10-15 minutes without touching devices with your Apple ID (as it also resets all server side settings)
- Open home and create a new home. It will be with old architecture. If you want to check if it was downgraded you can check if it’s possible to add an iPad as a hub (with new architecture it’s not possible, or, more obvious, to check if there is an upgrade banner in the Updates menu)
And you'll be up and running again on all your devices.
