summary data shown on the ecowitt.net dashboard are the values from the
console and can be changed by the user in the console. At ecowitt.net no
summarizing is done for the displayed tiles, just display of what the
console sends. What is shown there is user responsibility. If the user
makes adjustments, they are simply taken over and displayed. => you can
only conditionally expect accuracy in the summary counts - it may or may
not not match the really stored 5-minute (or longer period summarized
data depending on the retention policy) data. (we can see the
discrepancies between import summaries, NOAA summaries and dashboard
tile summaries)
If there is a discrepancy between this summary data shown on the
dashboard tiles and the summarized end-of-day data for rain, this is
most likely user caused. (800+ vs. 470)
Data from the import was all properly stored - discrepancies are likely
to be user caused and not we_import caused.

I have spent this morning working through the csv data, the NOAA
format reports on your web site and the data on Ecowitt.net. There are
a couple of issues going on. First, the bulk of the difference between
the Ecowitt.net yearly rainfall (presently showing 824.1mm) and that
imported by wee_import (approx 507mm) is due to data inconsistencies
on Ecowitt.net. The yearly rainfall value displayed by Ecowitt.net is
taken from the yearly rain field (presumably uploaded by the station).
If you look through the 2023 tabulated data for the station on
Ecowitt.net you will see the yearly rainfall value was non-existent
until 6 June when it took on the value 585.1mm, but if you sum the
monthly rainfall values from 1 January until 6 June you get something
of the order of 254mm (it is impossible to say exactly due to
discrepancies between the values in the various Ecowitt.net rain
fields). This accounts for some 330mm of the difference. I have also
found at least one place where the Ecowitt.net rain data goes
backwards (23 February 06:00 monthly rainfall is 5.6mm, the 10:00
entry indicates 0.8mm fell taking the monthly total to 6.6mm, the
14:00 entry shows no rain but the monthly value jumps back to 5.6mm),
whilst this may or may not impact the import (it depends on how the
import is setup) it begs the question are there other data
discrepancies that may impact the import. I haven't yet checked for
any other similar discrepancies.
I have also noticed discrepancies in the NOAA format reports. For some
reason the 2023 report shows the March rainfall as 100.8mm, whereas
the March 2023 report shows a monthly total of 105.6mm. The archive
and daily summary tables both have 105.6mm for March, but for some
reason the monthly report is off. Ecowitt.net also shows 105.6mm for
March. Similarly in October. The October 2023 report shows 28.4mm but
the 2023 reports shows October with 27.1mm, the archive and daily
summary tables both record 28.4mm. I will have to look at this
further, but at present I would be wary of rainfall in the yearly NOAA
reports; the monthly reports seem to show the true value.
So far I have not been able to fault wee_import.
