Probably the information in this FAQ. It works very well, many of us are using it now. It’s an official integration, you just have to get the smartapp from the marketplace section of the SmartThings mobile app:
Hello, New user switching over from Vera. Go most everything back up except my Hub. I’ve installed the app, signed in and the hub is found. I select my hub, click next and nothing happens. I’m pushed back to the last screen. Under “things” I can see the hub and it will show me the current activity, but that’s it. IS this normal? Do you not get any control of activities and/or devices. Maybe I;m expecting too much. Thanks
