I know I can add a picture for a room, but I really want to add a picture for a thing. Is that possible? If not please add it to the feature request list.
Edit: I’m a dope… Click on the thing, then click on the gear icon, then “set device image”
Edit 2: Apparently I can add pictures to some things, but not others. For instance I can’t set a picture on my ecobee 3.
Apparently I wanted canChangeBackground instead of canChangeIcon. canChangeIcon only gives you the options built into smart things like these… http://scripts.3dgo.net/smartthings/icons/
