OK, so I was using these terms without knowing them :)

No wonder the OP is confused.
In Europe, METARs generally don’t have SLP, they have QNH stated as a “Q

Perhaps I can help as I own both an Ambient and Ecowitt weather station.
I recently did a major rewrite of an older Ecowitt barometer calibration
procedure and the new procedure should work with any Fine Offset
manufactured device with a barometric sensor.
Some basics regarding this equip

Rainer, Greg,
thank you both for thoughts and hints. Indeed, when I wrote "When
calculated by Weewx itself ("software" option enabled in weewx.conf), my
weather station shows 1001 hPa - still too low", I meant what Weewx
calculates and show on my webpage, not on console's display - display is
from the wiki page I sent
For example, the FineOffset consoles can display either the station
pressure (called 'absolute' pressure) or the station pressure plus an
offset (called 'relative' pressure). T
So Fine Offset equipment just does pressure badly.
So get station pressure into weewx,

yes - why not calibrate your console first
when you see that the offset between absolute and relative pressure for
your location used is wrong, just adjust it 😎
the the first basic step I'd say
even though, when your absolute (=local) pressure reading is correct,
and your have the weewx option
