DWD global weather (warning) integration

Feature Requests
1

This is a feature request to include the ability to pull or get pushed information from the DWD (Deutscher Wetterdienst), the national German weather service.

This service not only releases detailed forecasts for the weather, it also issues warnings for serious weather conditions, there are several categories, like snowstorms, hailstorm, heavy rain, thunderstorms, which then get a detailed start and end for each region as well as a severely-level.

This could be quite useful for automation in Germany.

Btw:
Sadly this service is limited to Germany only and I don’t know a service which offers those detailed warnings on a global bases just picking up the data from each national weather service - this would be gorgeous.

So if somebody got some sparetime for setting up such service, this would be gorgeous. :slight_smile:

Just to give you some impression which data is available by this service:

And this are some of the “warning” categories, you see the filter-view for the pushes here.

Would be nice! +1

The documentation of the API is extensive and they offer everything from raw data to nice graphics for usage by third partys.

Really lovely!

FAdditionally the DWD also provides global data via FTP-Access (after registration) wherever they get data from other weather stations around the world.

https://www.dwd.de/EN/ourservices/gds/gds.html

I guess this would be a good datasource for a global weather plugin for access beside the existing freemium DarkSky plugin.

I bet they would enjoy a larger userbase for their services.

We just need to make sure, that we check the timestamps from a directory listing and only pull new files if they really changed (according to the timestamps), to not excessively causing unneeded traffic.

The datasource is FTP, but I guess it’s fine, Python got a nice FTP client which allows easy access to the files on a FTP side.

I think we should head in this direction, because it would allow one plugin to cover more than just Germany.

Edit: Replaced link with the link to the English version.

This is my implementation:

Did anyone do any automation to send push notifications when a weather warning is coming?
if yes, can we share it, please?

Thanks in advance

A few days ago it seems DWD has changed to HTTPS and redirects every request vom http:// to https:// which makes the integration fail:

Error fetching data: <PreparedRequest [GET]> from https://www.dwd.de/DWD/warnungen/warnapp_landkreise/json/warnings.json?jsonp=loadWarnings failed with HTTPSConnectionPool(host=‘www.dwd.de’, port=443): Max retries exceeded with url: /DWD/warnungen/warnapp_landkreise/json/warnings.json?jsonp=loadWarnings (Caused by SSLError(SSLError(1, ‘[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:720)’),))

Good to know theat i’m not the only one.

There was a problem with the certificate which DWD fixed lately.

thx for sharing, nice work.

Can someone please adapt it for telegram, instead of sending email?

or does someone already use it with telegram, and can share the code?

my beginner copied code from different sources works (DWD WarnWetter markdown card):

send_dwd_warn_mail:

I use an http api i created from my own website. It uses DWD mosmix Data.
