Here is the situation. I have a Autelis Pool Control that inputs State Variables to ISY.
I was trying to figure out a way to create a differential temp value variable from 2 temp inputs in State tab. I am able to easily have the 2 State variables update 2 Interger variables I created (and don't even know if this is needed, but playing).
Basically, I am trying to set up a differential variable from 2 temp readings. If the differential variable is greater than 3 or 4 (degrees) then I would trigger a program to run (increase flow with pump, which currently works as programmed).
Is there an easy way to take 2 Interger or State variables and subtract the two to create a differential variable, and then program that variable to start a program when the total is 3 or 4 (or x) differential? All I am seeing is +-< etc.
If I can get this simple one going, it will open up huge amounts of things I could implement with everything else (solar, power, weather, Lux, etc).
What am I missing?
And Thanks for ANY input!
