I’m in the Austin area, we’ve got two day a week restrictions as well. However, I’m ignoring it… my logic; sure, I’m watering on days that I am not supposed to but I am using almost half the water (per week) than I was before Rachio. I’d make the case (with water bill in hand) to the city if they say something about a zone running on a even day. I was emailing with a water conservation guy from the LCRA about it. They’re actually cutting me a check for $125 to offset the cost of the Rachio 3.
As for watering times; I have St. Aug. and am worried about fungus as well. I just added a suggestion to have start times calculated back from the end time (sunrise) vs. running just after midnight. I’d like to water before sunrise but as close to sunrise as possible. Even if only watering for 20 min. I’d like to see Rachio do the calculation auto vs. me trying to set a hard start time.
Do you have your soil type, root depth, avail. water, etc… set-up in the Advanced zone settings? Are you setting the 24min/zone yourself? With Daily Flex on, mine is only doing a “heavy” water once a week. Additional short runs (~12 min.) on the zones with little shade the other days.
