Hi,
i have a similar Problem.
I update Windy with GET Parametes via https://stations.windy.com/pws/update/API-KEY
With a HTTP request i get data from my Station but on https://www.windy.com/station/pws-f0676497 i only get the spinning circel.

Edit: Deleting and recreating the Station fixed the Problem
Best Regards
Gregor
