no idea why @John Kilne had a different outcome

I’m not uploading to WOW-BE, but I can read documentation.  I was responding to the following request from Tom:

Could someone check the WOW-BE API and see exactly what they need. That should be what we do, rather than make stations "better" or "worse".

There was 3 of us getting wrong results before switching to absbaromin, the WOW-BE site was showing over 1100hPa, no idea why @John Kilne had a different outcome.

I'm having a hard time following. I know the last commit fixed David's station. John: I gather it made yours worse?

For me using absbaromin, pressure readings for my station being reported by WOW-BE were consistently looking very wrong.
They were approximately +10hPa higher than they should have been. Presumable the MSLP (barometer) being reported were then being (incorrectly) adjusted by WOW-BE to take into consideration the altitude of my weather station (around 105m).
As soon as I changed to baromin instead, things looked much better. So far the WOW-BE barometric pressures for my station have been stable with no anomalous readings.

Not using absbaromin things go wonky, my station was reporting over 1100kPa at one stage...

Just a query with regards to the updated restx.py file for sending data to WOW-BE.
When reporting pressure using "barometer", shouldn't the respective WOW-BE field be "baromin" instead of "absbaromin"?
According the the WOW-BE site:
"baromin = relative pressure (i.e. pressure reduced to sea level) and absbaromin = absolute pressure (i.e. the raw pressure measurement at the station’s location)."
So for reporting pressure:
   - weewx parameter "barometer" corresponds to the field "baromin" in WOW-BE
   - weewx parameter "pressure" corresponds to the field "absbaromin" in WOE-BE
May be I'm wrong, but since I modified the code to report "barometer" as "baromin" the reported pressure now seems to be correct (before the change they were abnormally high).
I have a Davis Vantage Pro 2 so it makes sense for me to report "barometer" pressure since this is what is provided by the weather station.

I've submitted a pull request for restx.py to enable sending weather data to both wow.metoffice.gov.uk and wow.meteo.be, the code is slightly modified from the diff that glennmckechnie posted to issue #1013

You can download a copy of restx.py with the changes here:
https://github.com/evilbunny2008/weewx/raw/refs/heads/master/src/weewx/restx.py

Just replace the existing restx.py which resides in /usr/share/weewx/weewx/restx.py when you install using the Debian package, I don't know exactly where it would be for other install methods.

The above file is from the current weeWX master branch and only tested in weeWX 5.1.0 on Debian Bookworm running a 6.12 kernel from backports.

I have limited python experience and would value suggestions to make the code more pythonic if needed.
