OK. Let's put a bit more logging in bme280wx.py, we'll just look at
pressure for now. Move aside your existing /usr/share/weewx/user/bme280wx.py
by renaming it as bme280wx_orig.py. Download the attached bme280wx.py and
save it in it's place in the /usr/share/weewx/user directory. Leave debug =
1 and restart WeeWX. Post the log including WeeWX startup and the first
half dozen loop packets.
