As an FYI - Z-Wave supports up to 5 taps (depending on device), as well as "Hold" and "Release" for a button.
However, Hubitat has only defined capabilities for up to 2 taps, plus hold and release. There are various kludges in drivers to handle this either using custom attributes or by mapping the extra taps to buttons. For example, a two button device might register push, hold, tap, double-tap on buttons 1 and 2, but map triple and 4x tap on button #1 to a "phantom" button #3 having them appear as a single / double tap. I find that approach a bit confusing and in drivers I've written I define a new attribute "multiTapButton" which can handle up to 5 taps on a button (I explain that method a bit more here: Homeseer HS-WD200 Dimmer Button Mapping with drivers here GitHub - jvmahon/HubitatCustom), but there really isn't a standard way of doing more than 2 taps.
