Time Frame Considered before Watering?
I'm a new user of RainMachine, and I'm excited about the feature that will query a nearby weather station for actual rainfall amounts prior to running a program.
On June 13th, the forecast was for 0.16" of precip, and it was going to be an evening storm. The rain arrived later than expected, and was heavier than expected. The storm eclipsed midnight, and I received 0.01" on June 13th, and 0.64" after midnight (June 14th).
My program was set to start @ 3:00am June 14th, just a couple hours after the storm ended. Earlier in the day, the program was planning to run about 40% of the program due to past rain and the 0.16" forecast for the day.
However, when it ran its final simulation 9 minutes before the program start time, it decided to water more than planned, even though the storm dumped more rain than was forecast.
From what I can tell, my RainMachine asked my nearby weather station for the actual precip total for June 13th, and it responded correctly with "0.3 mm" (0.01 inches). That, plus the 0.01" from June 12th and the "realPrecip" total shows as 0.6mm (0.02 inches) since last watering. So, it appears that the additional 0.64" that the weather station experienced after midnight was not taken into consideration.

If I run a program at 3:00am, will RainMachine only consider the previous calendar day and ignore any precip from the current day? Heavy rain after midnight is rare for my area, so not a huge deal - but just curious. What if I run a program @ 8:00pm? Will precip from the current day be considered then?
Thanks for reading this long post! I enjoy getting to know more about how the RainMachine makes decisions.

RainMachine waters for the future and corrects for the past. If you have a daily program, today it will water for tomorrow evapo-transpiration but it will add/remove any extra/under watering that he did for today (calculated yesterday). With the observed data, that we always receive 1 day in the past, the correction is done at the next watering. There are no weather services configured in the RainMachine that get the same day observed data, mostly because it will be difficult to work with observed partials when correcting.
