I was asked in another discussion a while back about a way to see all temperatures in a single view, and while this could be done with Rooms and putting all your temperature devices in a Room, it’s really not a logical way to group devices (IMHO).

The list isn’t sorted because I couldn’t figure out how to do it with the example code base I used, but I still find this app helpful for my needs:
