Debugging

You can turn debug off on config.ini -> debug=false

The log you find in /var/log/RadioTemperature

tail -f -n 200 /data/log/RadioTemperature/current

You can check the status of the service with svstat:

svstat /service/RadioTemperature

It will show something like this:

/service/RadioTemperature: up (pid 10078) 325 seconds

If the number of seconds is always 0 or 1 or any other small number, it means that the service crashes and gets restarted all the time.

When you think that the script crashes, start it directly from the command line:

python /data/RadioTemperature/RadioTemperature.py

and see if it throws any error messages.
