Thanks for the great update!
I've already updated this on my weather page:
https://www.nimmervoll.org/wetter/wetter.php

However, as you can see, the evapotranspiration data is calculated up to the beginning of the year.
However, the sunshine duration is only calculated from the update onwards.
Is it possible to calculate this retroactively?

Hi what tag do you use: sol0!total-lastval:2 or something else to send to your website?

Hi,

for the year I use:
[sol0total-yearsum=h.1:--]

Sorry, no backward calculation offered.

it's also working when I send the data to meteotemplate; THX!!

according to chatgpt to mimic a blake larson sunshine duration sensor, 50 to 70% of the theoretical sunshine radiation is required. or 120W/m2 (WMO).
