If you are still interested in getting the data with Eikon API you may try to get the data from the RICs that we already have. You may navigate to RIC <EU/WEATHER> that is a landing page for the European Weather Service from there you can reach to <EU/WEATHER4> for forecast data. Then to <0#DE-FORECASTS> that contains weather forecasts for Germany and from there you can chose Dusseldorf 1 day ahead <0#DUSSEL-D1>, then you need to narrow down the hour from the available options e.g. <DUSSEL-D1-06> and right here you can get temperature, rainfall, wind speed, wind direction and pressure.
That may look quite cumbersome but is set up in a logical pattern.
RICS = ['DUSSEL-D1-06'] fields = ['GN_TX20_12','GN_TX20_14','GN_TX20_16','GN_TX20_17','GN_TX20_18'] df,err = ek.get_data(RICS,fields) df
This is how it looks compared with a quote
