Gary,
thank you for your post. It has been helpful. I have made some progress
now.
First I think I might be confused about how to set up my config file as to
whether I am using the SDR option or the Acurite Option when configuring my
station. I have come to the conclusion that choosing SDR is correct (I am
using an SDR to read the data from my weather station as opposed to having
the station directly connected to my Pi).
Using you suggestion and configuring for the Acurite option I was able to
get the parser to show the total rain (rain_in) when I ran the sdr.py
code. However, when I ran the weewx in direct mode, it said it could not
find the device on USB. So I went back to choosing the SDR option. I then
went to the SDR class and found where the sensor_map section was and added
a line for my rain_in fully qualified name. Then when I re-ran the sdr.py
code I was still getting the rain_in/rain_total values showing in my parsed
data and when I reun weewx in direct mode it is working again, although no
rain data in the loops or in the records. So that is some progress at
least.
Also, I am still not getting any rain data when I look at my generated web
page.
