This topic revisits a fundamental problem with the Rachio UI. The parameters for configuring a zone are based on the assumption that the zone is watered uniformly, such as a lawn or dense plantings with spray irrigation. Precipitation rate (which now is weirdly named “nozzle inches per hour”) is suited to that type of irrigation but is not meaningful for point irrigation, such as drip or bubblers.
Point irrigation is based on applying water at a known rate to a plant with a known canopy and root area.
Why should a user need to do calculations (assisted with a calculator spreadsheet) in order to enter these parameters into a UI that is based on an entirely different model for watering? This makes the process way too complicated.
The Rachio UI already asks what type of irrigation I have. If the answer is drip or bubbler, it should ask for inputs that are meaningful for that type of irrigation, such as flow rate, number of emitters, size of the plant, and anything else that is relevant. Rachio should then convert those inputs to whatever internal model it is using to make watering decisions.
