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). Windy has no control over it and only its owner can remove it.
Its data has absolutely no effect on the local weather forecast by weather models like those shown in Windy.
For reporting you’d better rely on the WMO weather station at Mace head. Note that other personal weather stations (pws or madis) along the coast rather report temperature in the same way as Mace Head.
