I think you are using my driver? [DRIVER] Zooz ZEN Switches Advanced (and Dimmers)
There is a graphic at the bottom of my post that shows the tap mappings.
For a 2x tap you will also get a "doubeTapped" event along with the "button 2" pushed event. Use whichever one you prefer. I like using the doubeTapped event with the button controller app because it fits into the grid layout.
