+1 for cover entities. I had this working with a cover and for some reason it stopped working and then I looked at the github page and it says it's not supported :( not sure what happened.

+1. Would love to support volume for a minimal zone volume control. I don't think there's any reason it shouldn't be able to since the attribute, min, and max can all be specified.

+1 i was hopping to use this with a number/screen brightness entity

Would be lovely if input booleans could be added as well, using these to bypass automations when lights turned on manually.

I vote for input_number entities. :D
