I'm only using a sprinkler system to water St. Augustine grass on a .2 acres in South Florida. The entire area is flat and has the same soil make-up (loam). Direct sunlight shines mostly all day on every area other than a small 10'x40' strip on the west side of the house that is shaded part of the day. I have no trees and no plants. I have a Sprite controller and 1 whisperer sensor which is connected to the 3 zones that get the most sunlight. The learned % is at 55%

I don't see any benefit in using the whisperer. Thoughts?
