Thanks for the response. Today I did set both thermostat extreme temperature settings to the same value as a temporary work around. The wife was upset when the house temperature got set to 63 degrees last night, the Sunroom setback was applied as the House setback. It is easy to verify the bug: set different extreme temperature setback deltas on separate thermostats, and observe one setback value is applied to all thermostats when extreme temperature is triggered at 10 PM. I can log a ticket at alarm.com if this would help.
But for now I can work with it as-is until the next Alarm.com updates, or 2Gig firmware rollout if this is related. This issue is closed since the schedules are now working and I know you have the toolset to correct if I have difficulty again.
As a side note, I hope for alarm.com feature improvements (this Spring?). I am trying NOT to deploy a Vera /Smart Things / Revolv. I hope the control features of alarm.com improve so I do not have a multi-controller solution which would be more difficult to manage. Some of the things I would like to do are:
-Not lower the shades if the window is open, to avoid rain damage.
-Turn on an overhead fan while the AC is blowing, and turn off 3 minutes after the AC motor stops.
-Raise the temperature, or turn off the AC, if the window is open for more than 5 minutes.
-Integrate the sprinkler control schedule for a single UI for all home control.
-Alarm if rain is expected and windows are open.
-Integrate the Sonos for audio annunciation, or scene control.
