First "Best wishes for this new year to everybody".

Meteohub reports:
actual_rain0_total_mm 10.2 = exactly the total rainfall this year (1 and 1/2 days)

Yesterday at 23.59
day1_rain0_total_mm 3.00 (never a figure after the decimal point)
Now :
day1_rain0_total_mm 7.00
When you add those two figures it is more or less equal to the total rainfall this year of 10.2 mm

But: Meteohub reports:
month1_rain0_total_mm 9.20
year1_rain0_total_mm 3.80

I can't find a set of measurements to put on my website so that visitors don't joke about it.
Now it looks like the attached picture from my website http://www.weerstation-wilsele.be

Same for me (and for Emjaynet in the '2 days' thread, I see). On the front page, my ajaxdashboard has:

This Month: 6.90 mm
Season Total: 6.00 mm

and the figures are repeated in the Trends page. This seems to be because Season on the main page and Year on the trends page both use 'year1_rain0_total_mm', which is lagging behind the up to date month figure in 'month1_rain0_total_mm'.

Using 4.8i on an iconnect.

i got an answer in dutch so here a short translation:

The sensor values are calculated with a different interval. Not all at the same moment. Some frequent, some only once a day.

day1 calculated every 5 minutes
month1 calculated 4 times a day
year1 once a day

This site has a table with more info:

Yep, good detective work!

I guess you only really notice in in the first few days of Jan as rain for day can be larger than rain for year.

You will notice the difference all month during January i think because month can ge greater than year as it rains on a day.

Therefore i switched to

actual_rain0_total_mm

which contains the correct rainfall for this year.
