Show currently used position values for OpenWeatherMap

My Openweathermap integration seems to work fine, but the current cloud coverage just seems wrong. I look out of the window and see blue sky, and the cloud coverage reported by OpenWeatherMap is above 80 percent.

I want to check the longitude/latitude settings.

How do I show the current values being used by OpenWeatherMap?

Edit:
Found a similar question. Then had a look in that file .storage/core.config_entries. The coordinates for OpenWeatherMap are correct nearly exactly my house. But the current cloud coverage reported by OpenWeatherMap is 80 percent. A look out of the windows shows full sun.
