Finally got back to this. Using simple commands would be a lot easier than the smarthings/webcore approach. Unfortunately, Simple Commands is NOT seeing the state change for Ring when the alarm is triggered. It can see and issue commands to change the Ring state to armed home/armed away/siren on/siren off etc, but when the alarm is triggered, there is no change in state so the routine I wrote to turn on lights and set off a utilitech siren does not execute.
Did you turn off two-factor authentication to get this to work?
I have seen a thread, https://simplecommands.zendesk.com/hc/en-us/community/posts/360034851934-Ring-Alarm-Triggers that seems to confirm that ring triggers are not working in simple commands.
What am I missing?
