Need Help Removing Persistent Ghost Eve Switch Devices from Home Assistant 8.3 Matter Integration on Home Assistant Yellow

Hello everyone,

I’m running Home Assistant 8.3 on a Home Assistant Yellow with SSD storage. I’m having a persistent issue with ghost Eve Light Switch devices reappearing immediately after I delete the Matter integration and re-add it.

Here’s what I’ve tried so far:

  • Deleted the Matter integration and removed devices via the UI; the old devices still reappear after re-adding the integration.
  • Tried purging the database completely using recorder.purge service with keep_days: 0. This clears history but does not remove ghost devices.
  • I cannot access the hidden .storage folder via the File Editor to manually remove device registry entries (core.device_registry and core.entity_registry).
  • I have Samba Share installed and accessible, but I am unsure how to safely edit those JSON registry files to remove ghost devices.
  • Factory resetting my Home Assistant Yellow with SSD feels complicated and I’m hesitant to do it without proper guidance.

My goal:
To completely remove ghost Eve Matter devices from Home Assistant so I can do a fresh and clean integration with both Google Home voice control and the Eve app environment.

Specific questions:

  1. Can someone provide a clear, step-by-step guide on safely editing .storage/core.device_registry and .storage/core.entity_registry via Samba to remove ghost devices without corrupting the files?
  2. Is there any way I can fully reset the Matter device registry without factory resetting my entire Home Assistant Yellow?
  3. Are there known best practices for adding Eve devices to Home Assistant Matter integration, especially for users also using Google Home and the Eve app?
  4. If a factory reset is my only option, can someone provide the simplest possible step-by-step instructions for safely factory resetting Home Assistant Yellow with SSD?

Thanks in advance for any help!

Does this mean you have removed it through the HA UI or the Matter Server addon UI?
