Just tested here, works fine. Are you sure the API key is valid and functional?

Hey,
I created the key from "Weather API for Developers" and copied it from the wunderground site:
- Stratus plan, Developer
- Where will it be used? -> Other
- Commersial? -> no
-mobile chip? -> no


_
EDIT:
I testet it in the Browser:
For San Fransisco it works: "/api/{API_KEY}/conditions/q/CA/San_Francisco.json"

The program seems to ask for this: "/api/{API_KEY}/conditions/q/51,5837,8,18158.json" and this throws "querynotfound"
_

Copied from Key ID. Do I have to do something else? Or can I test the key otherwise?

Greetings, Ben

Hey,
okay, I had an idea and I testet to select a bigger city in germany (eg. Dortmund). Now wunderground works well in ekos.

Do I have to select predefined towns? Because I created an entry for my location in kstars and this doesn't work.

Greetings, Ben

Ah, it's a locale issue. I fixed it in the current code, you'll get an update tomorrow.

Thanks for the quick support, that's great.
