I know this is an old post, but I’ve just joined the community here and I’m starting to play with integrating Automagic (which I’ve used for years) with SmartThings (which I’ve only been using for about a month). If you use @joshua_lyon’s SharpTools, you can control SmartThings stuff from Automagic. I’m currently working on using Automagic for a geofencing solution (see this thread), but I threw together a proof-of-concept flow that turns on one light, and sets another to a certain dim level:
You have to have the things you want to control authorized in SharpTools for them to show up in Automagic, but once that’s done the Automagic piece is pretty simple.
