@azdavidr, I appreciate all your help on this. I'm currently in AZ and new to Rachio. My landscaper set up one of my zones to include both trees and shrubs (all on 2 gph emitters) but trees with more emitters, and shrubs with less. I was wondering how to go about using your spreadsheet you included with mixed zones? I was hoping I could just add up all my Emitters # of GPH (like 50 total [25x2gph]) to make it simple??
