Dear Dhar,

iIf you turn on the smart zone mode, Netro will skip smart watering and programs when there is large amount of rain(>0.2inch/ 5.08 mm) or watering regulations and manual restrictions.

 If you do not want smart zone schedule to override your own programmed schedule, you can set up the Smart Zone level from Advanced to Basic(Settings->Zones->Smart Zone), which only skip rainning days for your programmed schedule. 

For more information about Netro smart watering, here is an article about Netro three watering modes which might be helpful. https://netrohome.com/forum/posts/111 

Thanks,
