When smart lighting was first introduced with mobile app v2, it allowed for multiple instances to be created, so many of us have multiples.
A couple of updates in, they changed it so that now you can only install one “parent” With all the multiple individual named “children” still separate.
But you have multiple parents left over from the original version unless you individually delete them.
It’s frustrating that there’s no easy way to review all the rules we have set up. I literally have spreadsheets taped to the back of the door.
