Openweathermap + netatmo

Hey guys,

I’ve been searching and trying and can’t really get this to work.
I’ve got a netatmo weather station that I’d like to send data information to openweathermaps.

Does anyone have a clue of making this happen and how to do it?
Don’t really get the API stuff on their websites and how to use it.

Can someone maybe help?

best regards.
Martin
