Hi Javier,

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(>0.2inch). Currently Netro will skip your schedules only on previous day and rainy day so Netro still waters your zone based on your program(water every 3 days) the next day after rain. 

If you do not want Netro to water your zones after the raining days. You can customize it in Settings->Preferences->Days to Skip, and select days to skip, for example, next day and next 2nd day.

Thanks,

Netro Support
