I think I have this working, maybe. The APRS extension to weewx creates
a text file with a weather packet, such as:
/272050z4355.97N/06956.34W_031/003g006t000r000P023h37b06495WX-Topsham,Maine
I have a script that reads that file and sends the packet with:
xastir_udp_client localhost 2023 N1JOV-7 (passcode) -to_rf -to_inet
"/272050z4355.97N/06956.34W_031/003g006t000r000P023h37b06495WX-Topsham,Maine"
where (passcode) is my 4 digit APRS passcode.
Within Xastir I can see the packets being transmitted via the RF link,
and can view them from another APRS station over the RF link.
However, I (perhaps incorrectly) assumed that the weather data would
show up under the "weather" tab on aprs.fi:
https://aprs.fi/weather/a/N1JOV-7
I don't see anything, and I also don't see the "raw" weather packets on
aprs.fi either.
Am I misunderstanding how weather data works, or is it just not doing
what I expected?

There is a WeeWX extension to generate APRS packets and write them to
a file:
https://github.com/cavedon/weewx-aprs
If I can get that to work, I can write a simple bash script that will
read that file, and use the Xastir command "xastir_udp_client" to send
the data to either the RF port, the Internet, or both. Call the script
from a cron job that runs as often as needed.
I should be able to do some simple checks to ensure that the same data
isn't sent twice (ie, if the file hasn't been updated, don't do
anything).
Assuming all of that works, I'll be able to use WeeWX to send the
weather data to the Internet servers directly, and to generate the
html files to be able to view the weather station data directly, then
enable the above script if I want to send the weather data over RF
using Xastir.
I'll let you know how it goes.
