Feature Request: Nest Hello as a button

[davglass]

First off, excellent project! It all worked out of the box for me!

I recently switched from a Ring to a Nest Hello and one feature that the Ring supported was appearing in SmartThings as a button. Then you could attach automations to this button press. For example: Turn on the Foyer light when the button was pressed.

Any change you would like this fearture? I'd be willing to give it a go and try to make it work.
