the data saved into the basic sensor csv file is:
Time,Indoor Temperature(℃),Indoor Humidity(%),Outdoor Temperature(℃),Outdoor Humidity(%),Dew Point(℃),
Feels Like (℃),Wind(km/h),Gust(km/h),Wind Direction(°),ABS Pressure(hpa),REL Pressure(hpa),Solar Rad.(w/m2),UVI,
Hourly Rain(mm),Event Rain(mm),Daily Rain(mm),Weekly Rain(mm),Monthly Rain(mm),Yearly Rain(mm)
(possibly with different units depending on your console settings)
=> the next record written after a change of the rain values will contain the new changed values
