Hi pixelworld,
only owners can manage scenes, in your case, only you can do that.
Invited members (home members) can only run scenes.

Single biggest problem with Ewelink. When I leave the country my wife don’t have admin rights. So she is stuck when I am not home. I Should not of bought so many sonoff devices! It is suppose to be a smart HOME. And a home is occupied by a family, not only one person.
