How to see full calculations inside smartirrigration??

[lynxchat4]

I have an Ecowitt GW2001 weather station. I took all the data from it. It seemed to me that the watering was very weak. I made a test zone where I made a calculation only based on cloud weather data. And in the end it turned out that according to the data from my station, the watering calculation was two times less. I rechecked all the units of measurement, all the sensors are working. Tell me how to find the reason for such large discrepancies. (There has been no rain for more than a month)
