Your SSL certificate (Let's Encrypt R3 intermediate CA ) expired on 30 sep 2021 but the raspberry pi running cumulusmx still use it, so the solution was to disable the ca-certificate.
@tomslavkovsky I have been stuggling to get windy to publish my data. This screenshot worked a treat. For a complete novice it was very helpful. My first attempt did not work. I think my API had expired. I deleted my Old station added a new one, with the new API key I was publishing data on Windy in 3 minutes..........Thanks
This weather station is a personal weather station (pws). Apparently there is a problem with this station. The owner should fix it or stop transmitting the data. Windy can't fix it or delete the station.
This is why it is preferable to refer to professional weather stations when they are available.
@Ondřej-Šutera The filtering seems very strong in favor of wmo station. this wmo-4150 seems only to have data once a day. when data gets old the station does not show on map, but the pws is not shown either even it has current data all the time.
