On my old controller, my rain sensor was set to dry out about 2 days after rain fall. My rain sensor is adjustable and I reused the rain sensor and kept the same settings. I get the fact that the rain sensor will hold off watering for 2 days after rainfall on the old system. My question is, how does Rachio use this data. Does it just use it to confirm that there has been rain fall? Should I set the rain sensor to the lowest setting? Is there a pro or a con for keeping it set to 2 days? I would suspect that setting it to the lowest setting would work the best but was just checking. I didn't see this in the FAQ.
