HI @joerg, I have tested with different cities (also cities where warnings at the moment are available). My scripting solution for DWD-Unwetter is working here. Only the binding in OH3 didn’t work
Hi,
i have some debug-messages for this issue:
2021-05-13 18:35:16.786 [DEBUG] [.internal.handler.DwdUnwetterHandler] - Start initializing!

At the moment there is a warning for 27109476000 and I’ll get this: numberMatched=“0” numberReturned=“0”
A technical call auf the Website ist working also on the system:
curl https://www.dwd.de/DWD/warnungen/warnapp/json/warnings.json | less
Is there any idea for it? My scripted solution finds warnings for the cellid.
Very very strange …
Best regards,
Reinhard
Hi,
sorry for my late reply, but I somehow missed the message that there was a reply for me here.
Have you tried to enter the request URL direct in a browser?
For example:
https://maps.dwd.de/geoserver/dwd/ows?service=WFS&version=2.0.0&request=GetFeature&typeName=dwd:Warnungen_Gemeinden&CQL_FILTER=WARNCELLID+LIKE+%27808117002%27
The OH3 binding worked fine for me in the past and I got warnings issued for my city, but at the moment, the DWD warning server does not function at all, I get the following answer when I use the OH3 binding or if I enter the request URL direct in a browser:
<script/>
<ows:Exception exceptionCode="InvalidParameterValue" locator="GetFeature">
<ows:ExceptionText>Illegal property name: WARNCELLID for feature type dwd:Warnungen_Gemeinden</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>
Maybe this is only a temporary error.
Best regards,
Jörg
Hi,
at the moment the webservice seams to work. For this request:
https://maps.dwd.de/geoserver/dwd/ows?service=WFS&version=2.0.0&request=GetFeature&typeName=dwd:Warnungen_Gemeinden&CQL_FILTER=WARNCELLID+LIKE+%27808117002%27
I’ll get this response:
<ows:ExceptionReport xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ows="http://www.opengis.net/ows/1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0.0" xsi:schemaLocation="http://www.opengis.net/ows/1.1 https://maps.dwd.de/geoserver/schemas/ows/1.1.0/owsAll.xsd">
<ows:Exception exceptionCode="InvalidParameterValue" locator="typeName">
<ows:ExceptionText>Feature type dwd:Warnungen_Gemeinden unknown</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>
And this message I’ll didn’t get from the Log in the binding. My scripted solution works fine, so I think the “Warnungen_Gemeinden” ist not integrated in the binding.
If I have a look at WFS 2.0.0 at 2m Temperatur an RBSN Stationen from GeoServer: Willkommen
There is only this feature type available:
<FeatureType xmlns:dwd="http://www.dwd.de">
<Name>dwd:Warnungen_Gemeinden_vereinigt</Name>
<Title>Wetterwarnungen und Vorabinformationen auf Gemeindeebene (vereinigte Warngebiete)</Title>
For this call / request:
https://maps.dwd.de/geoserver/dwd/ows?service=WFS&version=2.0.0&request=GetFeature&typeName=dwd:Warnungen_Gemeinde&CQL_FILTER=WARNCELLID+LIKE+%27808117002%27
I get this response:
<ows:ExceptionReport xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ows="http://www.opengis.net/ows/1.1" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0.0" xsi:schemaLocation="http://www.opengis.net/ows/1.1 https://maps.dwd.de/geoserver/schemas/ows/1.1.0/owsAll.xsd">
<ows:Exception exceptionCode="InvalidParameterValue" locator="GetFeature">
<ows:ExceptionText>Illegal property name: WARNCELLID for feature type dwd:Warnungen_Gemeinden_vereinigt</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>
It seams that the WARNCELLID ist not the right parameter for the call.
Does someone has an idea for a workaround?
Best regards,
Reinhard
I assume there currently is a bug on the DWD geoserver.
As the error messages are changing during the last days, they might be testing new software at DWD. I recommend to wait some days, so maybe the problems will disappear.
As the OH3-DWD-Unwetter-Binding does not recognize this behaviour as an error, I suggest to add something like a “Status” or “Error” channel, so one can distinct between “no warnings available” and “service unavailable”.
Best regards,
Jörg
8.6.2021:
The problem seems to be solved.
But a “status” or “error” channel in the binding would be helpful.
Hi,
I have done some tests with different WARNCELLID’s. If have used my ID for “Gemeinde” (Amtlicher Gemeindeschlüssel – Wikipedia) and a prepended “8”.
Now I get Warnings for my “Gemeinde” (with “Landkreis” it didn’t work in the binding for my scenario).
Best regards,
Reinhard
Just some additional information:
A detailed explanation of the CQL_FILTER can be found here:
IMHO the current implementation is quite dangerous:
- An empty response from the DWD server doesn’t result in a message in the debug log. Get your WARNCELLID wrong, and you’ll never see a warning.
- There is no way to know the NAME of the region corresponding to the data. Get your WARNCELLID wrong (especially when using the wildcard %), and you’ll see wrong or no warnings at all.
So it is of utmost importance to get your WARNCELLID right:
-
- Lookup your Gemeinde/Stadt/Gewässer/… in Wetter und Klima - Deutscher Wetterdienst - Leistungen - cap_warncellids_csv - there might be several entries for your area of interest.
-
- Check your WARNCELLID by making a call to (without [ and ]):
https://maps.dwd.de/geoserver/dwd/ows?service=WFS&version=2.0.0&request=GetFeature&typeName=dwd:Warnungen_Gemeinden&CQL_FILTER=WARNCELLID%20LIKE%20%27[your WARNCELLID]%27
- Check your WARNCELLID by making a call to (without [ and ]):
-
- Please note that % within a WARNCELLID must be replaced with %25.
BTW, thanks to @malmix (see Obviously simple task: textbox to display item (string) with more than approximately 56 characters on the sitemap. But how? - #4 by malmix) I found a quite elegant way to embed long texts into sitemaps:
Webview url="http://<ip address>:8080/rest/items/DWDUnwetterWarnungen_Description1/state" visibility=[DWDUnwetterWarnungen_Warning1==ON] height=3
Image url="https://www.dwd.de/DWD/warnungen/warnapp_gemeinden/json/warnungen_gemeinde_map_de.png" visibility=[DWDUnwetterWarnungen_Warning1==ON]
hi all,
is this binding still broken ? (used the ‘official’ one)
just tried it during an active warning for e.g. this cellID :
“109189000”: [{
“regionName”: “Kreis Traunstein”,
“state”: “Bayern”,
“event”: “STURMBÖEN”,
“level”: 3,
“type”: 1,
“description”: “Es treten oberhalb 1500 m Sturmböen mit Geschwindigkeiten um 70 km/h (20m/s, 38kn, Bft 8) aus westlicher Richtung auf. In exponierten Lagen muss mit Sturmböen bis 85 km/h (24m/s, 47kn, Bft 9) gerechnet werden.”,
“end”: 1636045200000,
“start”: 1636009200000,
“headline”: “Amtliche WARNUNG vor STURMBÖEN”,
“instruction”: “ACHTUNG! Hinweis auf mögliche Gefahren: Es können zum Beispiel einzelne Äste herabstürzen. Achten Sie besonders auf herabfallende Gegenstände.”,
“stateShort”: “BY”,
“altitudeStart”: 1500,
“altitudeEnd”: null
}, {
“regionName”: “Kreis Traunstein”,
“state”: “Bayern”,
“event”: “WINDBÖEN”,
…
and i did not receive any warning…

as mentioned above, the cell is included in the warnings:
https://www.dwd.de/DWD/warnungen/warnapp/json/warnings.json
Same for me. I just see the updated timestamp, but get no values. I tried several different (active) IDs.
Is there a fix that can be installed manually?
Hello all together,
I put the jar-file into the addons folder and uninstalled the “original” DWD Unwetter Binding.
But the “new” binding doesn’t start.
The log entries says:
Error while starting bundle: file:/Users/PJH/openhab3/addons/org.openhab.binding.dwdunwetter-3.1.0-SNAPSHOT.jar
org.osgi.framework.BundleException: Could not resolve module: org.openhab.binding.dwdunwetter [286]
Unresolved requirement: Import-Package: javax.measure; version="[1.0.0,2.0.0)"
Can anybody help me?
Thank you and best regards. Paul
Hello all,
I installed the original binding under OH3.3 but could not receive updates.
After some searches in the internet I found these 2 links which helped solve the problem:
https://www.dwd.de/DE/leistungen/opendata/help/warnungen/cap_dwd_profile_en_pdf_1_12.html
and
https://www.dwd.de/DE/leistungen/warnungen/neue_warngebiete_aufstellung.html
In my case the root cause was a new cell_id for the community I am living in.
Maybe it helps some of you to solve the problems.
