the fields are oblivious of how the data stored was achieved (min, max,
avg, sum ...).
This is defined in the accumulators for the weewx field map - and if
your new variable is not contained or you want a different way from the
default accumulator behaviour, you have to add this to the [Accumulator]
stanza in weewx.conf
I suggest your study the weewx customization guide in the weewx
documentation - I think most if not all of your questions are answered
already there.
Your scenario is in principle described there - independent of the
driver. Also how and where to define new units - or assign existing ones.

If you get stuck, come back here 😁

Thank for your response. How to distinguish between accumulative
fields and now accumulative ones?
Is this done into the weewx config file? And how about specifying the
units (KW, Joule, etc)?

Hi all,
I have a weewx station running using the fileparse driver for
about 4 years now.
All variables are read periodically from a memory file. Now I
want to add two additional measurements from a solar panel.
Namely I need to store (and show as respective graphs) the
current power in W and as an accumulative variable I would
like to store (and show) the generated KWh values.
My question is: do I need to add those two fields into the db
manually or is there an automatic way. Those two measurements
are already present in my fileparse file together with the
respective values.
What else should I add to the weewx config files so to define
the nature of the variables (accumulative, etc).
Please help me to complete this task
BR
Maria
