Small script that pulls gas prices from Tankerkönig and writes them into an InfluxDB
- Python 3 (may work with Python 2 - didn't test it). Optional: I recommend the use of pipenv which can be installed with
pip3 install pipenv. This keeps your python installation clean if you use several different python versions and modules. - Tankerkönig API Access - you need to register for an API Key at https://creativecommons.tankerkoenig.de
- influxdb python package
- A running InfluxDB instance
- Rename or create a copy of the
.examplefiles, which should be edited now to your needs: - Set proper values in tankerkoenigToInfluxDB.conf
- Lookup gas stations GUIDs here and add them to stations.conf. Be aware that you don't add empty lines to this files, as they will be interpreted as invalid UUIDs
The scripts loads all available gas prices for each gas station listed in stations.conf from the tankerkönig API. Then, it writes them to InfluxDB.
Run pipenv install to install all requirements. You can enter the environment with pipenv shell. In this shell you can now run the script with python tankerkoenigToInfluxDB.py. You can also run the python script directly with tankerkoenigToInfluxDB.py, but you have to make the script executable first: chmod +x tankerkoenigToInfluxDB.py
You can add the script to your crontab to run it every 5 minutes or so:
*/5 * * * * /path/to/tankerkoenigToInfluxDB.py >/dev/null 2>&1
If you want to use the python virtual environment provided by pipenc you should add this script:
*/5 * * * * /path/to/tankerkoenigToInfluxDBWrapper.sh >/dev/null 2>&1
Make sure that you adjust the path to your installation of the script correctly. It is currently set to /path/to/tankerkoenigToInfluxDB. Depending on your configuration you'll might need to add the path to the pipenv executable to the PATH variable of the tankerkoenigToInfluxDBWrapper.sh script.
