Need help with creating a device type - custom actions

I am probably posting in the wrong forum, I couldn’t find the developer forum.

I created a device type for my smart things shield. I am using a regular button, but now I want to add another button doing the same exact thing. (It is sending a signal to an arduino pin, and I want to target another pin).

So I need help with how to create a custom action. I assume I need to declare something somewhere. (The documentation mentions that you can create custom capabilities, but I couldn’t find any documentation on that, which I assume if I could do that, I could define more actions. Barring that, is there any way to pass a value into a normal action?

For example, I am using the “push” action, but if I could pass in a value to that, I wouldn’t need a custom action. Maybe someone should overload the push action to accept a string. Does the smartthings language support overloads? If it is based on java it should.

I’m open to any other ideas on how to accomplish this or any critique of what I have done. Here is what I have at the moment:

// handle commands
def push() {

	zigbee.smartShield(text: "push").format()

def push1() {
	log.debug "Executing 'push1'"
	zigbee.smartShield(text: "push1").format()


more text so I can post

Have you found a solution? Because I’m stuck on the same problem
