Questions, answered
What is the single biggest water waste in home irrigation?
Watering on a fixed calendar through rainy weeks. Forecast and saturation skips eliminate it, which is why weather intelligence outranks every other feature for savings.
Do soil sensors beat weather modeling?
They answer different questions: sensors measure your actual soil; models estimate it well. Netro and Hydrawise let data-driven owners combine both.
Can a controller detect a broken pipe?
Only with flow sensing: Hydrawise with its meter, or LinkTap at hose scale. Standard controllers infer nothing from pressure or flow.
Will saving water stress my lawn?
Properly tuned cycle-and-soak with soil modeling usually improves root depth. Lawns suffer from shallow daily watering more than from smart skipping.
