Usage with InfluxDB

If you wish to store data on server, using InfuxDB, check influx.py

Automatic data collection To automate data collection, using crontab will be easiest way:

1. Edit crontab: crontab -e
2. Add job. If running Aranet4 with 1 minute intervals, run script veery minute:

* * * * * python /PATH_TO_THIS_REPO/influx.py XX:XX:XX:XX:XX:XX anrijsAR4

3. Save and close crontab.

History upload It is also possible to upload history to InfluxDB. In this case run command: python influx.py XX:XX:XX:XX:XX:XX anrijsAR4 -h

To limit record count, add -l <count> parameter.
