I was surfing the web about Home assistant one evening and came across instruction on how to setup a map of your devices (using itunes as device tracker) on the main user interface perhaps in one of the groups. Now I can’t find out how that is done.
I’m not sure if this is what you are talking about, but if you use the icloud component, then if you click on the map link at the left side of the screen, it will show you a map of where your devices last reported. I’m not aware of a way to do this using itunes.
