@LG-ThinQ-Integration Can you look at this PR and let me know what you think? I think having a way to at least fixate entities is a nice way to make sure every device exposes the right stuff like expected

Oh, you made tests for us. I really appreciate it. I think it is great. We'd better add tests based on this commit.
