There a lot of interest in integrating SmartThings with external alarm panels (DSC, Honeywell, etc.) Unfortunately, SmartThings API is missing standard alarm panel device capability. I believe adding alarm panel to the list of SmartThings Capabilities would help better integration of alarm panels with SmartThings ecosystem.
Here’s my alarm panel device capability RFC for anyone to comment:
Name: Alarm Panel
Preferences Reference: alarmPanel
Attributes: panelStatus - [“ready”, “notReady”, “armedAway”, “armedStay”, “alarm”],
Commands: armAway(), armStay(), disarm(), panic(panicType), bypass(zone, on_off), setCode(string)
