AD2SmartThings

Nate, the SHM API is undocumented. I stumbled upon the API calls to sync the two states and I haven’t seen anything that specifically says the smoke has alarmed. If you do find anything please let me know and I am happy to help improve the integration.

I have connected smoke alarms and followed this thread to integrate mine with ST:

I took this one step further and added another zone to my Vista panel called house smokes and hooked up my Kiddie relay to this zone. Now when my Kiddie smokes alarm they make my Vista panel alarm and ADT gets notified.
