Downgrading HomeKit back to old architecture

This solution worked for me.

For those who are not sure how to do it.

Open the URL via your phone or tablet (IOS Device), and then go to Settings --> install the profile.

First, close the Home app and make sure it is not running in the background. then from the phone setting find Homekit, and click on reset. if you have an older Apple device that uses the same iTunes account, it's better to do it on the older device (at least worked in my case). once you reset the Homekit. go back to the home app and add a new home.

In my case I am using Phillips Hue Bridge at home, I didn't have much trouble since the Phillips app kept the Bridge and devices for me I just needed to add the bridge and then all sensors/lights/devices started showing up. all needed to do was categorize them again in Apple Home which didn't take more than 20 min.

Good luck and thanks @Frenkieboy for the help.

This solution is perfect, thank you!

Can you delete profile after ?

Thank you so much!!! It worked!

I realize this is a later response, but hopefully it will help someone.

I also had the issue where I have no Home app option in settings. It turns out you have to do the following:

1. click the link at the beginning of this thread and follow those instructions
2. go to settings > general > VPN (because why wouldn’t it be there?? So stupid) and you should see something about the profile thing you installed (I forget what it says). It will say something along the lines of “installs a button to reset Home configuration”
3. Follow those steps, THEN you’ll magically have a Home option in settings again.
4. Go to the heretofore MIA Home option in your phones settings and tap the reset home configuration, or whatever it says.
5. That’s as far as I’ve gotten but I wanted to post this before I lost the motivation to do so.

this solution works.

to clarify a few key things:

1. The web address is CASE SENSITIVE. It will provoke an error if you don’t get it right.
2. you must install the patch. The patch creates a button that didn’t previously exist in settings for Home (kit). When you enter this, it will have a button in red for “reset configuration”.
3. you must reset on all account devices this same way and wipe HomeKit out (delete our Apple home setup altogether)
4. YOU MUST wait the mentioned 15 minutes.

this was awesome. I have Sonos throughout the house and do NOT need to waste money on an Apple hub. As I used to say about 20 years ago “mad props!”

There is an error in my previous post: it is about 2024. You will also have to do the same procedure for those you want to share your house with, otherwise they will not receive the invitation.

Instructions worked fine for restarting with old architecture and a new home. However, all existing home devices won’t connect as they say they’re part of the old home!

So now in a problem of re-adding all Home devices back. Then manually disconnecting them from the updated home. Then on the downgraded “home” you can then add them.

And the pain is all your Home settings are gone! So my reco is…

1. Screen grab your existing home setup so you know what you need to get the new one to look like.
2. Remove each home accessory one by one in the existing home set up.
3. Follow OPs instructions downloading config file and downgrade.
4. then you can add your old accessories to your new, downgraded home.

Actually this solution worked flawlessly for me; ¡thank you very much!

My problem isn't iPad as hub, it's that older versions of the Apple Watch don't support HomeKit with new architecture. And this method still works as of 29.04.2023 iOs 17.4.1. But you need another profile, replace KeepLegacyHome in the link with HomeKitReset, install this/both profiles, then reset the iDevice (Settings -> General -> Transfer or Reset iPad -> Reset -> Reset All Settings) and „Home“ will appear in Settings menu. The rest is as in the first post. Good luck to everyone!

I contact the genius bar and there is no solution for now. No downgarde available.

Maybe in the 17.1

I tried this with Apple support and using the link/info here and it didn’t work as of July ‘23. After the architecture update, my automations stopped working and my iPad is no longer/won’t be a hub. I’m not buying extra equipment just to make an app run. Giving up on HomeKit and Home until they let users use it the way they want, need, and can afford.

I tried installing and I get the error:

Profile Installation Failed

The profile "Home reset configuration and keep legacy Home architecture" is no longer valid.

What are my options now?

I can't seem to even use my HomePod with my 2015 MBP Monterey anymore.
