I set the zones initially with the information I had about my zones and the head types but the Iro system is recommending too much water. I think the system can’t tell that my heads and zones overlap and share the load. I have information from irrigation water catcher cups / gauges I set in the yard. I want to adjust the recommended times to account for this information while not adversely affecting the adjustments for recent weather or seasonal adjustments. What is the best way for me to do so?
As an example, my front yard gets the equivalent of 5.4 in per hour (minimum from 8 catch cups) on fixed spray heads. Rachio system recommended 18 minutes every three days! I think it should be 10 minutes every four days. I usually water every 4 days in April. But it is a warm and early start here this season. Maybe your system is adjusting for this? But 18 minutes every three days sound more like an August / maximum amount than a March target when the temps have yet to exceed 80.
