Physical Buttons/Switches for ST

#1

I’m wondering what kind of physical buttons/switches people use to trigger things within ST.
I currently have a spare Hue Dimmer laying around, is there a way I can get this to work directly with ST?

I don’t have any experience with Hue, but do use the Xiaomi buttons and also an Iris fob. These work great with ST and are also integrated into some of my pistons.
