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). Your one time run schedule was skipped by rain restriction. You can check it in the schedule page.
If you want to run your one-time run schedule, pleases use the "run a cycle now" feature. Please go to Settings->Programs, choose your one time run, scroll down and tap "run a cycle now" and Netro will start watering instantly.
