I think I have this figured out. It looks like if your command is named "setXXXX", then the current state xxxx will populate into the first box? Example is setLevel, setHue, setSaturation I noticed all work.
Can this also work for an ENUM? If I make a ledMode attribute and populate it with the current setting will the drop down pre-select from the menu?
Yes I can just try but before I fight with it, would be nice to know if there is any chance of it working.
It looks like it can work for custom command also, not just built in. This one does not work correctly since White is not a number value, but it is trying.
