Personally I use this to handle my delay: [Release] SHM Delay Version 2.0
It creates a virtual contact sensor that waits to ‘open’ X number of seconds after the selected contact sensors open.
I’m using the DSC version of Alarmserver but it should work for the Honeywell branch too. I just set my AlarmServer DelayExit Doors as the source for one delayed entry contact sensor and set the delay on this smartapp greater than the exit / entry delay on those three real contact sensors (also turn off ‘real’ night mode.)
Bonus - the virtual contact sensors should work with STHM as well as SHM.
