I would like to be able to customize the smart watering feature. Unfortunately, the application rate calculation for the sprinkler specifications seam to be incorrect. For example, I use hunter mp rotator rotary spray nozzles to irrigation a specific section of grass. They have a really low application rate at about 0.4 inches per hour. In comparison, I have another section of lawn where I use Rainbird RVan rotary sprays with an application rate closer to 0.68 inches an hour. Using the default settings for rotary sprays does not account for this range of application rates. When I use the customized mode smart zone function and I input the application rates for the sprinkler specifications, the calculation for duration increases to above 3000 minutes! Am I missing something? It would be incredibly helpful if I could be able to customize smart watering based on the application rates of my sprinklers.
