I’m having the same issue but with cover.garage_door which is provided by the now removed (and no way to get it back) MyQ integration. So there is no way to re-enable the entity via the Integration and no way to even install the integration as it’s toast.
I’ve seen references here on editing files directly, but there are also comments on that shouldn’t be done, and besides, I’m not sure how to even locate those files, let alone edit them. There’s no step by step guide or documentation as someone said because end-users aren’t expected to be editing them, but the UI isn’t able to address this issue, so we are all a bit stuck.
With the recent demise of MyQ, I can’t be the only one with this same problem…
