iOS 16.4 Beta Re-Adds HomeKit Architecture Upgrade

The iOS 16.4 beta that Apple provided to developers today appears to reintroduce the HomeKit architecture update that was pulled from iOS 16.2 due to a wide range of ‌HomeKit‌ bugs that it added.

In the Software Update section of the Home app, iPhone and iPad users who have not yet upgraded to the new architecture are seeing a "Home Upgrade Available" option after updating to iOS 16.4.

There were signs that the ‌HomeKit‌ architecture would be reintroduced in iOS 16.4 as early as January, as Apple has been working on it behind the scenes for some time now. Apple has prepared an updated version of the update, presumably with fewer bugs that will impact ‌HomeKit‌ users.

The new ‌HomeKit‌ architecture is meant to improve the reliability and efficiency of communication between smart home accessories and Apple devices, and it is something that Apple has been developing since iOS 16 was announced at WWDC in June 2022.

The initial launch caused some ‌‌HomeKit‌‌ devices to go missing from ‌‌HomeKit‌‌ setups or to be stuck with a "configuring/updating" status. It also resulted in invitations to share the Home with others failing, and it broke ‌‌HomeKit‌‌ Secure Video recording for some.

Very interested to know if people who already upgraded with 16.2 will be asked or required to upgrade again.

The first time it wiped all my homekit connections, and I'm not up to finding the codes on every lightbulb in my house again...
Yep, same here. It destroyed my HomeKit Home, with over 100 devices. Had to set up from scratch. Fun times.

Ever since upgrading to the new artichecture, my Level Lock has decided it no longer wants to respond at random times. Updating all my HomeHubs to 16.3.1 seemed to fix it but now it's right back to where it was. I've tried adding and re-adding, changing the batteries... nothing works.

I also had issues with Phillips Hue. It was so bad I started switching away from Hue... something I've wanted to do anyway.. but I never had any issues until updating the architecture.

I'm at the point where I may just start a new home and begin the tedious process of re-adding everything.

I'm hoping 16.4 squashes these issues once and for all. HomeKit in my opinion is the most finicky Apple service I have ever used.

DO NOT UPGRADE even when this releases.

It has been a nightmare ever since I did with 16.1, and nothing works.
It’s been fine for me ¯\_(ツ)_/¯
