Though I understand your comment it may not be as hard as you might think if you tried. Heck you could probably use the Arlo Virtual driver I created as a base with a few changes to make any simple driver you could need. Before that driver i had never created one either.
I guess the question is what would it need to be able to show if you did setup SAS with Smarthings, and what are the potential options it would show.
Is it simply motion and then a classification of what the motion is. Maybe I can put something together for what you need.
