I’ve had my Rachio 3 setup for 3 days now and set to use Weather Intelligence Plus and NOT my PWS. However I notice that the soil moisture records and history continue to show precipitation data and weather data coming from my PWS ID for the last 3 days. hmmm. i’m trying to understand this, is it because this is the nearest station (obviously) to my home as I thought Weather Intelligence Plus was blending the data of many PWS’s in the area and other data sources to estimate such things as the rainfall at my location?
Anyway can we get a geeky article about how Weather Intelligence Plus works? What variables besides PWSs are used? Forecasts? Actual radar estimates of rainfall etc?
