Hi Luca,

By default, Netro will skip the schedules(including manual schedules from user programs) when there is a chance of significant rain(>0.2inch=5.08mm). 

You can use the expectation to see if it works beWe 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.

Thanks,

Netro Support
