after seeing your view , debug info, that you emailed me
the issue is your raw barometer reading is very low
and so you need to set a barometer offset in WD
to bring that up to expected sea level reasing
e.g , in hpa, if you current barometer reading should be 1020, but your raw reading is 660
then the offset needs to be 1020 less 660
i.e 360 hpa
or
10.63 inches
