There is no way to currently delete an entity that was created from a template binary sensor where the Entity ID no longer exists. Lots of posts about editing YAML or the database, but we need to be UI first. I have attached images of the issue, and hope to get support for a UI based solution.
well, u’d better kinda figure it out → as i’d assume that would be a bug to fix → there would be no need to delete an entity without an id, if there would be no way for entity to become id-less…
