When viewing the widget on my iPhone, it always shows the last location that I was looking at while in the full app. I have the app set for ‘current location’ when I open it, but the widget doesn’t follow that setting. I have to open the app and get my current location, then the widget will show my current/correct location.
@ivo True that. After a lot of looking, I finally found out how you could access the Deutscher Wetterdienst weather data. You just need to create an account in the links provided. Hopefully, you will be able to use the data I provided. I've checked, it should be available in XML format. The ICON model should be in there.
