I use weewx with a Netatmo rain gauge. It works well but I cannot figure out how the total amount of daily rain is calculated.
Since Python is too hard for me to learn, I use php coding to query the database. The other day we got 25.8 mm of rain. A figure reported by my Netatmo app on the iPhone and on the Netatmo web page. Also very close to what I could read on an old fashioned measuring glass in the garden. So the figure 25.8 mm is definitely ok. The graph in weewx also shows 25.8 (hard to read exactly, but somewhere between 25 and 26) (see image). Now: If I look at the table archive_day_rain for that specific day it says sum=2.5654 (also wsum=2.5654). How is 2.5654 becoming 25.8? Difference between sum and wsum? I also queried the archive table with sum(rain) for all records for that date. As a result I got 2.5654, the same as in the sum column in table archive_day_rain. So the question is: How is the original data from Netatmo actually stored, and how is it that the graph shows me the correct amount? Very puzzling for me! /Valley Here is a picture of the graph [image: raingraph.png] <about:invalid#zClosurez> -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
