I second @wx16 suggestion to @benblackmer. I live in Georgia where we have spotty pop up thunderstorms. The closest official station is over 20 miles away. There are two PWS nearby, one 6 mi north and one 6 mi south. We had a nice 1 hr gentle rain (.25") the other day that neither station registered. The beauty of the rachio is it’s ability to use actual weather data in its calculations. Temp, humidity, wind, etc. are valuable pieces of the puzzle. However, the most valuable piece, rainfall, is also the most variable. Fortunately, it is also the cheapest for a home user to collect. A $10.00 rain gauge will give the most accurate data available. There should be a way to enter that data into the calculations. IMHO.
