Our algorithm downloads past, present, and forecasted weather data for your zip code from the NOAA. It uses information like precipitation, cloud cover, temperature, and rainfall to power a machine learning (ML) classifier and make irrigation decisions. Our algorithm has been extensively trained and tested, and has been proven to save large amounts of water and money without damaging lawn. In recent pilot tests, residential water use was decreased by 81% and lawn health acutally improved. More detailed information about our algorithm and testing can be found here.
