Here are two useful commands for you to try to monitor the situation
Check that indi is working
====================
$ ps aux | grep indiserver
You should see a line saying that indiserver is working, it will include the command including indi_weatherradio
Check the output of the logfile
=======================
$ tail -f /tmp/logfilename.txt
Instead of /tmp/logfilename.txt put in the path to the log file you used in the service script
This will show the output from the indiserver being put into the log file.
-f means follow and uou need to press ^C to get your command prompt back again.
Changing verbosity of indi
====================
You can increase the amount of information that indi outputs by adding extra v to the service file.
