Was something changed recently that broke the SmartThings integration?
Everything showed as offline (I used to see the controller and each zone). So I removed everything and started over.
Now in the Classic app the zones and controller appear, but the Controller thing is the only one that responds to commands.
In the new app nothing works at all.
Not a deal breaker as I only use it for maintenance troubleshooting, but for now I have to resort to the iOS app.
