Describe the bug

I just found https://github.com/DTekNO/lovelace-meteogram-card and it was exactly what I was looking for. However it reports:

Missing data: rainMin, rainMax, windDirection

Some supported features cannot be plotted because the required data is not provides.

The question is if this is just missing in the component or if DWD doesn't provide the data.

Hi, rain is reported by DWD as a single value for each hour. So there is no min or max value.

The wind direction is already provided by dwd_weather.

I had the wind direction not in degree. So that issue is solved.

DWD MOSMIX data does include precipitation ranges: RR1u1 (lower bound) and RR1o1 (upper bound) for 1-hour precipitation. We could expose them as precipitation_min/precipitation_max and sum them up?

Nice catch! I'll implement this, however I need some time for this as I'm currently on vacation.

HA core's Forecast TypedDict doesn't define precipitation_min/precipitation_max, but extra keys in forecast dicts survive JSON serialization through the websocket API. The meteogram card already looks for item.precipitation_min and item.precipitation_max. So if we add it that way, it should work with the card.
