Online help from Google is out of date, functionality often doesn't work. It claims to link devices that are in home app, but you can't use half of them because for some reason Google home and mini can't see them. Google has moved towards more $$ and to hell with the customer because they have a monopoly. Google must be broken up & regulate, no matter how distasteful that might be for some. Google's motto used to be "do no evil". It has become "Evil is okay, as long as there's profit in it."
