The homebar is perfect for controlling lights. However it lacks the ability to control Lutron Radio RA2 scenes and keypad trim buttons. Although additional homebar scenes can be created to replicate a Lutron scene, they are not integrated (maintained) and still, there is no way to add trim keypad buttons to the homebar.
In addition, it would be great to integrate Lutron Radio RA2 button feedback so scene buttons in Simple Control have accurate feedback.
Others feel free to chime in if you think this would be useful.
