Hey Jim, sorry for the delay in responding here!
I’ve got a working SmartThings setup and I see nothing on this dashboard. How did you go about setting this up? You’re using the “new” SmartThings app, right? I made a little demo a while back: SmartThings demo. If you were to follow along in this demo, what happens after you log in? It should tell first tell you a list of devices imported from our side, then they should appear on the dashboard. Do you at least see the list of devices?
