Wim, does WD34 interpret the barometer setting that comes from the Weewx Cumulus realtime.txt file. It always appears high compared to the reading on WU and on my Acurite display. I realize this is probably a Weewx problem, but wanted to see if anyone has experienced the same problem.
My weewx site is https://klephtic-math.000webhostapp.com/index.php and my WU site is https://pendulous-here.000webhostapp.com/
