3 reasons to delete them over adding "added_to_node": true in this Discovered Contacts File:
- If you add a node with added contacts in the integration these
added contact will not be added to this Discovered Contacts File
- If you remove an added contact from your node, in HA this contact unavailable etc but in Discovered Contact File this contact become orphaned and gets harder to remove (not impossible solutions are delete Discovered Contacts File or manual action)
- It reduces the size of the Discovered Contacts File.
As (temporarily?) workaround I have created a Manage Contacts BULK action/card which can be found:
