My solution to this was a man in the middle virtual alarm with a smart app running that relays its state based on a configurable delay. I have this virtual “Alarm Relay” device tied to SHM, which will receive the appropriate alarms, the smartapp watches for state changes and forwards them on to the actual hardware after some preset time.
The smartapp will instantly relay the “off” command so you’re not stuck with the alarm sounding if you disarm SHM. Additionally, there is a configurable setting to ignore the delay (and instantly sound) during specific modes.
Code for the smartapp is below. If you are trying to install it and have any issues/questions let me know.
