luftdatenpumpe 0.21.0

About

Process live and historical data from luftdaten.info, irceline and OpenAQ. Filter by station-id, sensor-id and sensor-type, apply reverse geocoding, store into TSDB and RDBMS databases (InfluxDB and PostGIS), publish to MQTT or just output as JSON.

Features

1. Luftdatenpumpe acquires the measurement readings either from the livedata API of luftdaten.info or from its archived CSV files published to archive.luftdaten.info. To minimize impact on the upstream servers, all data gets reasonably cached.

2. While iterating the readings, it optionally filters on station-id, sensor-id or sensor-type and restrains information processing to the corresponding stations and sensors.

3. Then, each station’s location information gets enhanced by

   • attaching its geospatial position as a Geohash.

   • attaching a synthetic real-world address resolved using the reverse geocoding service Nominatim by OpenStreetMap.

4. Information about stations can be

   • displayed on STDOUT or STDERR in JSON format.

   • filtered and transformed interactively through jq, the swiss army knife of JSON manipulation.

   • stored into RDBMS databases like PostgreSQL using the fine dataset package. Being built on top of SQLAlchemy, this supports all major databases.

   • queried using advanced geospatial features when running PostGIS, please follow up reading the Luftdatenpumpe PostGIS tutorial.

5. Measurement readings can be

   • displayed on STDOUT or STDERR in JSON format, which allows for piping into jq again.

   • forwarded to MQTT.

   • stored to InfluxDB and then

   • displayed in Grafana.

Synopsis

For a full overview about all program options including meaningful examples, you might just want to run luftdatenpumpe --help on your command line or visit luftdatenpumpe –help.

Screenshots

Luftdaten-Viewer displays stations and measurements from luftdaten.info (LDI) in Grafana.

Map display and filtering

• Filter by different synthesized address components and sensor type.

• Display measurements from filtered stations on Grafana Worldmap Panel.

• Display filtered list of stations with corresponding information in tabular form.

• Measurement values are held against configured thresholds so points are colored appropriately.

Map popup labels

• Humanized label computed from synthesized OpenStreetMap address.

• Numeric station identifier.

• Measurement value, unit and field name.

Installation

If you are running Python 3 already, installing the program should be as easy as:

pip install luftdatenpumpe

At this point, you should be able to conduct simple tests like luftdatenpumpe stations as seen in the synopsis section above. At least, you should verify the installation succeeded by running:

luftdatenpumpe --version

However, you might have to resolve some prerequisites so you want to follow the detailed installation instructions at install Luftdatenpumpe.
