This one is especially for our German friends (the forum translates each message, so read it in your language): here is DWD, the official weather alerts from the Deutscher Wetterdienst in Gladys. In Home Assistant, more than 4% of installations use it, with Germany being the top country for HA. The data is open, free, without an account or key.
What it does
A device per zone: each house located in Germany (based on its position), or a municipality or district entered manually. It provides the current alert level (0 to 4), the upcoming level, the number of alerts, the main alert and its type, usable in scene conditions.
A « DWD Alerts » widget: now, upcoming, the list of alerts with their period, and the official text with instructions by touching an alert.
Two triggers: « alert issued », filterable by level and type (thunderstorm, wind, rain, snow, ice, heat…), with the title, period, description, and instructions in variables; and « alert lifted ».
An action « Current DWD Alerts », with a summary ready to send.
The cool part
Level 3 or 4 alert → message « {title} from {start} to {end} » and shutters closed
Wind or thunderstorm from level 2 → « Put away the garden furniture »
Every morning at 7 a.m., if there is an alert → the summary on Telegram
Accept access to the position of the houses (a house in Germany is found automatically), or enter the identifier of a municipality (the action « Find an alert cell » provides it).
Add the devices from the Discovery tab.
To have the names in German, set the integration language to « Deutsch ».
Honest small reservations: only Germany, the detailed texts remain in German (the only language of the DWD data), and the reading is done every 10 minutes by default. This is not an official alert system: NINA and WarnWetter remain the reference. It has been tested on real DWD data, but not yet in a real Gladys.

Thanks for picking up the small oversights, and sorry for the duplicate! I’ve strengthened the checks on my side: we read the thread just before starting, and again just before publishing.
Both integrations with their widgets among each other. Regarding weather warnings, no major differences. So far, they work perfectly, we just haven’t had a storm yet
My suggestions for improvement:
For some widgets, I had to enter the location of the house again in the widget, even though it was already selected in the configuration?
The display of pollen does not make sense if all are at 0, where is the rest or why are only three shown. Here, one could limit it to active pollen, because grasses are in summer and trees in spring or similar. Or all are zero.
I find the location and time information great, they are consistent and correctly assigned for my location.
And maybe someone else feels like tapping into the Federal Environment Agency? They have a similar location division and provide the AQI, i.e. the Air Quality Index for particulate matter, ozone, etc… then you would have a fine-grained pollen, weather and air widget for Germany and much more accurate than a superficial look from Openweathermap.
But all in all, I am enthusiastic about your work, very well done. I will try scene control soon.
