Run a program only when device changes from a specific value

[raymondh]

I would like to have a program execute when my Elk alarm disarms from a stay instant status only. So for example, if the alarm is disarmed from an armed away status, don't run.

 

Is there a way to do this!

Yes this is done as a program. Have one program set the ISY variable to 1 when you arm to away mode. Then when have a program that when you disarm the alarm it sets the variable back to zero. Then have a program when it sees the variable change from 1 back to 0 run the program you want. You do have to the Elk module for the ISY. Hope this helps.

I would suggest having the Elk close a phantom relay and have the ISY trigger off of the relay closing/opening. This would also require the Elk module, but I think it will trigger quicker.
