Newbie here... I just installed a Gen 2 16-zone unit to control my 12-zone system and did a quick audit of the consumption. Currently, we have a Mon/Wed/Sat directive. Before and after the Wed watering, I captured the meter readings and compared the consumption: Rachio weighed in a 497 gals in 75 min; the meter weighed in at 1621gals during that same period.
Several years ago, I did another test on individual zones and I have the #gals/min for each of the 12 zones. There appear to be a number of knobs to turn within the setup to affect the Rachio calculated value. I see where I should change several zones "flat vs sloped", but wouldn't that decrease the watering duration and decrease both the calculated and the actual?
What is the best knob to turn at this time to get the Gen 2 and the water meter to read about the same?
