Hallo Andreas,
It now looks like I have the basic system up and running. 
As you have already written, it is possible to retrieve the data from specified sensor_id’s. I could also provide a file containing the sensor_id’s.
Would this query be correct:
luftdatenpumpe stations \
--network=ldi --sensor=8228,76777 \
--reverse-geocode \
--target=postgresql://luftdatenpumpe@localhost/weatherbase \
--progress
I could also provide a list in a file with the sensor_id’s. Is it possible to include this list in the query so I don’t have to type all sensor_id’s in the query?
What exactly do I have to do to query the data regularly and write it to the influxdb so that I always have all the data?
Kind regards,
Oliver
