- Changing input water pressure only effects rate of flow. Rate of flow is measured by the flow valve.
- The “Variations in soul types" factor is already part of the controller’s configurable settings as "Soil Type” and it’s water retention properties as "Available Water" in advanced settings. This data is already used to regulate watering time.
- Spray overlap (throw) is configurable on most impact sprinkler heads via a diffuser screw. A knowledgeable installer will have head placement and throw properly set to achieve uniform coverage. This shouldn’t be an issue if it was installed professionally.
- If you read the selling points on the Rachio 3 Smart Controller before you purchased it, you would know it’s equipped with hyperlocal Weather Intelligenc Plus, a technology that uses satellite, radar and weather station data to make automatic weather adjustments based on your location. Here is the exact wording from Rachio:
What is Weather Intelligence™ Plus?
Weather Intelligence™ Plus is an exciting new feature available for Rachio 3 that provides hyper local accuracy into the current and projected weather that’s not only in your area, but right outside your door.
I’m not “anal” about the area of my yard, I’m just wanting the accuracy I was promised when making my purchase and square footage would be part of that equation. And, for reasons unknown, footage is one of the configurable advanced settings in the Rachio app.
