I have do not understand how the “scenes” are…
I tried to add a metatag ga “scene” to a switch, Google Assistant do not display a “switch” in the Google Home App and the interation with a “scene” seems to be only "ativate ".
After some tests, now I understand!
I can ask to Google to activate the scene. Even If there aren’t a switch in the interface.
I shall use the scenes in routines to group some complex functions.
