Pulling data hourly does not work

[DaemonNet]

When executing this code:

request = DWDStationRequest(
                station_ids=[5335],
                parameter=[Parameter.CLIMATE_SUMMARY, Parameter.SOLAR],
                time_resolution=TimeResolution.MINUTES_10,
                start_date=str(startBA),
                end_date=str(endBA),
                tidy_data=True,
                humanize_column_names=True,
                write_file=True,
                prefer_local=True
            )
            weather_df = pd.DataFrame()
            listOfElements = []
            for df in request.collect_data():
                 print(df)

I get the error:

    for df in request.collect_data():
  File "C:\Program Files\Python37\lib\site-packages\wetterdienst\api.py", line 223, in collect_data
    (df_station[DWDMetaColumns.DATE.value] >= self.start_date)
  File "C:\Program Files\Python37\lib\site-packages\pandas\core\frame.py", line 2902, in __getitem__
    indexer = self.columns.get_loc(key)
  File "C:\Program Files\Python37\lib\site-packages\pandas\core\indexes\base.py", line 2893, in get_loc
    raise KeyError(key) from err
KeyError: 'DATE'

It seems to me that getting data in any resolution smaller than DAILY is not supported. On the older package dwdweather2 this worked.

Dear @DaemonNet , thanks for coming back to us! First of all please include all necessary information in your issue so that we can fully understand what might have caused the problem (in this case also start_date and end_date would be nice to have).

I had a look into the parameters and encountered several problems:

• you should have received a logging that the given set of parameters is not available (climate summary is only available in daily resolution)
• we have a bug where in case no data is found we still filter it which throws this error

Thanks again for the issue and we'll pick this up as soon as possible!

Thank you so much for your fast answer. The issue with the parameter solved it! Maybe you can add a hint to the documentation (at least I didn't find it).

Dear @DaemonNet , we have recently added a "discover_parameter" function to the newly created class DWDObservationMetadata (https://github.com/earthobservations/wetterdienst/blob/342e0f2eb68b928706fe6593ab53622d53b63c7d/wetterdienst/dwd/observations/api.py#L423), which returns a json with all available combinations. You can freely define parameter, time_resolution and period_type there to filter it.

This is not yet available via PyPi though as we are still waiting to release the next version.
