Thanks for your effort, really nice addon. Is there a chance you’ll add forecasts / weather warnings anytime? (http://www.dwd.de/DE/wetter/vorhersage_aktuell/nordrhein_westfalen/vhs_nrw_node.html)

Greetings, Chris

Hi, thank you very much for your feedback!
As @leader21 pointed out there already is a plugin for weather warnings.
I can add forecasts which are available for most locations

sirhc

Uh, i forgot about the existing warning addon. Nevertheless, the forecasts would be nice! But no need to hurry
Thanks a lot

Released version 0.9.3

I had been noticed the record of weather data changes at the full hour and two time a days to provide accumulated values for precipitation and minima and maxima values for the days. This led to wrong values collected and strange bursts in the graph, obviously. Version 0.9.3 should fix all these issues.

Hello,

just an idea or information:
there is also a service from the DWD that is called CDC (Climate Data Center).
The free data is stored on a ftp and there are much more stations.
CDC FTP Site

Maybe this would be also a good data source for the plugin…

Thanks for the good plugin and your work for us!

@johnny11 Thank you very much for the pointer and the positive feedback! I had looked into this when I started creating dwd-weather, but found the data is difficult process and actually, I did not find all the weather data up-to-date.

The situation has slightly changed since then, however. Due to the political discussion on providing public access (“open data”) to all weather data of the DWD. As a result of this process, the DWD law has been revised to align with the GeoZG and international recommendations. DWD has also published a new price list which contains more precise information about the freely available services. Freely available weather data is provided via the "DWD Open Data Site.

More information on the matter:

Slightly off-topic: I have been struggling with a memory-leak in my setup which caused pimatic to terminate intermittently after a few days and I found pimatic-dwd-weather causing the issue. The past plugin release already contains some fixture to mitigate that, but it didn’t fix the issue completely. I have done another fix now and results look promising. I am just waiting for long running tests to confirm that. I’ll release a new release shortly.
