After installing the rtl software and the weewx software on my Pi 4 and
getting everything configured I am getting things to work as expected.
Just no rain data. I was expecting to have this problem because the
output from running the command sudo PYTHONPATH=/usr/share/weewx python
/usr/share/weewx/user/sdr.py --cmd="rtl_433 -M utc -F json" is missing the
rain data in the parsed section. Notice in the output below that there is
a value in the 'rain_in' for the out section, but that rain data is not in
the parsed section.

I have done a lot of searching on this forum and the web and I understand
that there have been many changes to the labeling of rain data on the
Acurite 5n1 system. Howerver I just can't figure out where in the code I
can make a change that will accept label that my version of the weather
station uses for rain.
I have done a fair share of programming and I have the help of my son who
is a computer science graduate. I feel quite comfortable messing around in
the code
So far the only change in code that I have tried was to change the line in
sdr.py
I am running rtl_433 version 20.02-55-gc1d1f9f branch master at 202005162227
thanks for your help
