If you turn on the smart zone feature, Netro will skip the schedules (including manual schedules from user programs) when there is a chance of significant rain(0.2 inch).
We noticed there's rain forecast in your area but Netro did not skip watering because the rain probability is small: 38%. We take the forecasted precipitation and multiply it by the probability of rain. If the result is 0.2 inches or higher, than we will cancel watering schedules. For example, if rainfall is 0.2 inches but probability is 50%, then 0.2*.5 = .1, 0.1 is less than 0.2, so the watering will go as scheduled. But if rainfall is 0.4 inches with 50%, then the Smart Zone will cancel the watering schedule for that day.
You could customized the weather restrictions now as well. By default, Netro skip schedules today and tomorrow if today rains more than 1 inch. You can customize it, like I want to skip the schedules on the day after tomorrow as well, or I want to skip if rain more than 1 inch. The setting is in "setting -> preferences -> rain".
