Playing with my first smartthings button: it doesn't seem possible to set it so that if [light] is off and the button is tapped, [light] goes on. and if [light] is on then if tapped [light] goes off. If you set the condition on the power state then the device is not available in the action. So, you have to use a tap for on and a double tap for off? Is that right? I was hopeful for the 1st way so I coudl essentially preserve the double tap for something else, thus allowing me more functionality. Is this accurate? In other words is there another way to make a single tap a power toggle rather than explicitly an "on" or an "off"?
