No response after 4.2.0

[kimwf]

Hello. HomeyKit devices not responding in HK after updating to 4.2.0. When I try to downgrade to 4.1.10, HomeyKit app does not longer run on Homey. Disconnected AppleTV hub functionality, did not to anything. Native HK equipment and homebridge bridges running fine. Any tips for rectification?

Same here, no response on 4.2.0, downgrading fails. I had forgotten I was on the beta channel.

Edit: I see the comment on the forum thread now regarding iOS 16.2. Maybe I can restore from backup tomorrow and change the app channel before it is upgraded

If you want to downgrade, try removing the test version of app first, then install the regular version. A backup restore should also fix it (if not, the backup process of Homey is broken).

It wasn't my intention to block a downgrade, I'll have to look at why that happens 🤔

However, there's nothing in 4.2.0 that should inherently cause problems with versions of iOS before 16.2, it's just an update of an internal library. Before doing anything, try a PTP or perform a HomeyKit reset which you can do from the App Settings page.

The issue is caused by 4.2.0 using a different format to store internal data. The current stable version (4.1.10) will crash when it encounters files with the changed format. I'll have to check if the internal storage directory of an app is removed when you remove an app.

A homeykit reset or uninstall will lose all devices from HomeKit I take it? In that case a Homey restore is probably less work.

[robertklep]

A reset will certainly cause all devices to be lost. However, I would suggest trying to see if the problem doesn't solve itself (with 4.2.0), perhaps after a while or (if you use them) toggle Home hubs off/on.

I use Homeykit and after the 4.2.0 update all devices are lost. And the app crashes.

I made a screenshot :

I will shortly push an updated test version of the app that will hopefully stop the crashes.

[robertklep]

Just pushed test version 4.2.1: https://homey.app/a/com.swttt.homekit/test/

Please let me know if it at least solves the crashing.

For people with non-responsiveness issues: you need to perform a reset.

• First, remove the "Homey" accessory from your home in the Home app.
• Clear HomeKit storage in the HomeyKit app, which you can do from the app settings page ("Clear HomeKit storage and start over"). You may possibly also need to change the bridge identifier.
• Then add a new accessory to your home, and add Homey back again (when asked for a pairing code, use 20020200)

If you want to go back to the stable version of the app, follow the first two steps of the previous process, then install the stable version of the app. You will have to set up HomeKit on your iOS device again.

The reason for all this is that I didn't realize the internal storage of the latest libraries is incompatible with the storage of the old libraries, and there doesn't seem to be a way to migrate the existing data 😭

No worries, Robert. We appreciate all your work, including that which breaks stuff 👍🏻

Restarting Apple hubs did not do the trick. I will try a restore.

[axelwathne]

Restore from backup did the trick, and I managed to switch to production channel before the app was updated. No repairing 45 devices today 💪🏻
