So, I have never messed with the back-end of this before (loading my own apps using code) but I think that is what I need for this project.
I have a small duck pond and a 400 gph pump in it with a pre-filter. I need to turn the pump off once an hour for approximately 10-15 seconds to allow some water to back-flow through the pump and partially clean the filter. The problem is if it stays off too long the pump does not want to start back up.
