Just installed composer HE and creating some custom buttons and scenes. I have several custom buttons which I use to call lighting scenes. How do I deactivate the scene from the same button I use to activate the scene? I created a toggle and tried that but it did not work. This is a new install and many of the scenes I am creating will be bound to actual buttons on keypads by my dealer because HE won't let me do that either. Surely there is a way to simply deactivate the scene instead of making another button just to turn it off?
