Hello rhaub101, I suggested it could be your catch cup information, because if that information is entered incorrectly then your smart watering will be off. Since looking at your catch cup information I saw that there is only one cup entry for each zone. I’d suggest watching the catch cup video, and reading the instructions again in the catch up section of the app for more accurate readings. When making changes in the watering schedule adjustments page you will want to adjust both settings. The Runtime adjustment slide bar will change your sprinklers runtime (longer or shorter), and is shown by percentage on the slide bar. Up at the top of the page just to the right of estimated duration, shows how long it will run. Then use the interval adjustment slide bar to determine if your system waters less or more often. These changes are displayed in the calendar above under estimated intervals. It shows the number of days between each scheduled watering cycle for each month of the year. Just so you know once you’ve set your changes, and leave this page the slide bars will revert to the middle so further adjustments can be made. Your previous settings are not lost, it’s just allows further adjustments to be made from the settings you previously set. Using these adjustments you can achieve your 21 min every other day for each zone. The spacing may not be exactly divided into three cycles of 7min, but you will still get the coverage you want. Please let me know if you have any further questions.
