Hello again,
here comes an update for every user who can’t use the german weather warnings app.
The OpenWeather app has included weather warnings now 
Version 1.2.0:
Add the new device as a child device for your location (like a forecast device).
You get sensor values for the current warning situation:
The app uses the OWM weather data. Depending on the source of the alerts, they can be a bit weired.
For Germany, the sour is the German Meteorological Office. But the alerts are sometimes duplicated in germyn and english - like in the example above. So please don’t wonder about such mixtures.
Here is an example of the OWM data:
As you can see, you can’t filter or group the elements. So it’s better than nothing 
You can use flow trigger and conditions for the alarm and the number of alerts.
The device displays a maximum of five warnings
This new functionality is only partly tested (there are not so many alerts today). So please report issues here.
PS: The alert descriptions are stored in capabilities which can be used in flows as global tags to send the content as push message or write it to the timeline.
