Thanks to
Open-Meteo and
Hoetzgit the WeeWX extension
weewx-DWD is not restricted to Germany any more. You can now create weather forecasts for every place of the world and include them in your skin by the
#include directive. Additionally, Belchertown users can directly replace the Aeris forecast by the forecast of other big weather services including DWD, MeteoFrance, and NOAA.
Weekday names and compass directions are actually available in german, English, french, italian, and czech.
The publicly available readings of the DWD (Germany) and ZAMG (Austria) weather stations can be included into the WeeWX archive record for display and saving.
(Remark: Using data provided by Open-Meteo requires linking to their website. And the weather services have their own terms and conditions, too. Please observe them when displaying their data in public.)
