Hmm, seems my initial diagnosis was somewhat off the mark and the problem
is a simple case of having trapped the wrong error. The fix requires a
simple change to one line of one of the wee_import .py files. If you are up
for it, on your WeeWX machine open the file weeimport.py (weeimport.py will
be in /home/weewx/bin/weeimport or /usr/share/weewx/weeimport depending on
your WeeWX install type) in a text editor of your choice. Look for the
highlighted line (it should be line 665):
try:
_temp = float(_row[self.map[_field]['field_name'
]].strip())
except TypeError:
# perhaps we have a None, so return None for
our field
_temp = None
and change it to:
try:
_temp = float(_row[self.map[_field]['field_name'
]].strip())
except (TypeError, AttributeError):
# perhaps we have a None, so return None for
our field
_temp = None
Save the file and then try your dry run import again. If you don't feel you
can make the modification let me know and I will provide some download
instructions.
One more thing. When I did a test import with the data file you provided I
received a warning about multiple interval values. WeeWX will handle
multiple different interval values; however, it could cause data integrity
issues if the derived interval is wrong. Looking at your data file I see
you have a one minute interval though there is a gap of some 7 odd days
around 22 September. When you use interval = derive in your import config
file this gap will likely result in an interval value equal to the gap for
the first record after the gap or the record will be ignored altogether. If
all of your data in at one minute intervals you can overcome the effects of
this gap/possible incorrect interval value by setting interval = 1 in your
import config file (note this will apply a one minute interval to all
imported records, so if your historical data later changes to say a five
minute interval you would need to split your imports).
