So, I have rain delay on and get the emails and history. What I'd like to see is, the following day is a record of whether it actually rained (rain assumption based on the same data source for the prediction of rain).
If a prediction turns out to be wrong, perhaps it makes sense to add a "fudge" factor to the next prediction given 2 days of an incorrect prediction in 90 degrees starts to really damage the flowers etc.,
Also, how local is the source of the prediction? Here in Atlanta, it can rain 1 mile away from me but not actually rain where I am. I think Rachio would do good to sell/recommend a real rain sensor that creates a grid system of rain "actuals" into their cloud database (i.e. in my neighborhood, only 1 of us needs that sensor if it's sensor is shared with all others in my neighborhood).
