Try the quick browse lists in the community – created wiki. If you go down to the bottom of that page, there is a “project reports” section. there are two lists there that you might find interesting.
The first is the “get started” list. It includes topics like “top 10 things to do with smartthings“ and “what device should I buy next?“
The second is the “impress your friends“ list. All kinds of fun stuff there, from a secret room to a magic wand.
Anyway check it out. This is a very creative community, and there are a lot of really cool projects.
