Matter / Thread node not deleted correctly

Questions & Help
1

I ran into what looks like an unrecoverable Matter state in Homey and I’d like to know if there is any supported way to clean this up.

I shared a Matter device (Eve Door Contact) from Apple Home to Homey using Matter multi-admin. During the onboarding process, Homey automatically installed the Eve app, which made sense.

Out of curiosity, I wanted to see how a shared Matter device behaves without its vendor app (since none of my other shared Matter devices required one). Homey warned me that deleting the app would also delete the device, which I accepted.

After that, the device disappeared from Homey’s device list, but when I tried to add/share it again, Homey reports that the device already exists. The device is not visible anywhere in the UI.

I then checked the Homey Developer → Matter tools, and the device is still listed there as a Matter node. However:

  • it is not visible as a device,

  • it cannot be re-added,

  • and there is no way to remove or clean up this “ghost” entry (the Homey fabric delete option is disabled).

This leaves me in a dead-end state:

  • I cannot use the device in Homey,

  • I cannot add it again,

  • and I see no supported way to remove the stale Matter entry.

This is currently a show-stopper for me, because it means a normal user action (removing an app) can leave the system in an unrecoverable state.

My questions:

  1. Is there a supported way to remove such ghost Matter devices from Homey?

  2. If not, is this a known issue / limitation that will be addressed?

I’m happy to provide screenshots or further details if needed.

OK, found it. Homey is like Windows. I restarted it and the node disapeared. Uffff.

It’s also like Windows in that it doesn’t make any sense, since apps provide nothing for Matter devices other than a pretty icon. All the Matter-stuff is handled by Homey itself.

That’s exactly what I was trying to find out as well. And yes — with or without the app, the device exposes the same controls and the same Flow cards. So I’ll just go without the app.
