Check out Keo’s thread for updates. I’ve made an app that connects SmartThings to AT&T Digital Life and allows you to arm/disarm the alarm when the SmartThings Mode changes. Mode changes to Night, alarm goes to Stay, etc. Automatically. Also, alarm is disarmed, mode changes to Home. The downside is that it requires a local server running on the local network with the hub. The good news is, a Raspberry PI costs only $35 plus some change for the power supply and case.
