Ah, you are running WeeWX v4 and this driver uses WeeWX v3 (legacy)
logging, hence the lack of control. Try this version of bme280wx.py, I've
changed the logging to v4 logging and changed the offending loginf to logdbg.
Rename your old bme280wx.py to say bme280wx_orig.py and then copy the
attached bme280wx.py in its place. Restart WeeWX and you should have a
quieter log, if you want to turn on the debug logging to see the bme28 data
in the log just set debug = 1 in weewx.conf and restart WeeWX.
If the driver fails because of an error on my behalf you can revert to the
copy you just made.
