what is this weather station?  is it something like a meteostick?  does it 
try to match exactly the behaviors of a davis console?

as you did before, run weewx directly so that you see loop and record 
output on the screen.  pipe that output to file, like this:

weewxd /etc/weewx/weewx.conf > /var/tmp/weewx-output.txt

in another shell, watch the output:

tail -f /var/tmp/weewx-output.txt

now tip the rain bucket of the weather station.  then tip it again.  (use a 
throwaway database if you don't want to pollute your real data)

to get even more details, modify the vantage.py driver so that it emits the 
serial output that it receives from the station.  that will tell you how 
accurately the weather station is emulating a real davis station.

the serial read happens around line 534 in vantage.py.  print out those 
bytes, or dump them to disk for analysis, then see if you can get someone 
with a real davis console to provide similar output for comparison.

if it turns out that the emulator is buggy and does not actually emit 
rainMonth, you could hack the vantage driver to use day rain instead.  look 
around line 1447 of vantage.py
