Apple introduced an updated underlying architecture for HomeKit and the Home app with the iOS 16.2 update. However, it had to be removed a week after launch because of bugs and installation issues. Apple assured users that the removal was temporary and that the upgrade option would come back soon. Now, it appears that Apple is getting ready to reintroduce the updated Home architecture. The backend code indicates that they are preparing a "version 2" and testing it internally. Apple did not provide a specific timeframe for when the architecture would be available, other than saying it would be soon. It is expected that an iOS 16.4 beta will be released after iOS 16.3, and it is likely that the architecture update will be included in that beta. The exact timing of the beta release is unknown, but it could be as early as this week. While Apple mentioned that the Sound Recognition feature, coming in a spring update, would require the refreshed Home architecture, it is possible that the architecture update will be released before Sound Recognition. According to Apple, the update enhances the reliability and efficiency of communication between smart home accessories and Apple devices. The company has been working on this update since iOS 16 was announced at WWDC in June 2022. The initial release of the new Home architecture caused some issues such as missing ‌HomeKit‌ devices, devices stuck in the "configuring/updating" status, failed invitations to share the house with others, and broken secure video recording for some users.
