Sorry to hear about the watering event. We did some research into your currently selected Weather Station, KCTWINDS20.
After reviewing the data, it looks like you changed to using a PWS (versus interpolated data) this morning (under Weather Intelligence Plus settings). Data on 5/27 is actually interpolated (since you were not using a chosen PWS but interpolated data), that is why it’s different than what you see the station reporting. When changing weather stations, data in the past does not change, even though the label of the station is changed. If you had chosen the station two days in the past, the graph would have reported exactly what that station was reporting for precipitation.
In regards to how to view the rain data WI is seeing on any given day, you can do this by viewing our Soil Moisture chart within the Zone Details screen of any Zone used with a Flex Daily schedule. I have included and highlighted your data for the Front Beds zone below:
