I’ve recently noticed this new option under Edit > Device Tile > Properties > Actions, but after tinkering with it a couple of times, can’t seem to figure out what it does or how it’s supposed to behave – b/c nothing happens when I later “Tap” the Tile:
At first blush, I’d have guessed it’s supposed to pop up and ask for a value input from the user, as opposed to a hard-coded value to send with a Custom Command.
