I hope I am not sounding rude, but are you using Google Home? I appreciate the help you are trying to render, but it seems that you have not read what I had typed.
First, I had mentioned that I had tried to add via Yeelight in Google Home. Light strip was added but not able to change color.
Second, I tried to add using Mi Home. Light strip was added but not able to change color.
Third, I notice that within Yeelight app, after I added light strip, the same light strip appears in Mi Home as well.
