Hi Vincent,
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. Please check if it is the weather restrictions. You can customize the weather restrictions in setting -> preferences -> rain, like I want to skip the schedules on the day after tomorrow as well, or I want to skip if rain more than 0.5 inch.
Thanks,
Wency
