"Customized" server upload on your console is not compatible with Windy protocol.
If you don't want to have your computer running 24/7 to upload to Windy, then I recommend either investing in a Raspberry Pi which is very small (run headless), almost no power use, economical, quiet if you get the Flirc case, and very reliable. It can run Cumulus MX.
If that doesn't suit you then you could also get a Meteobridge as that too is small, is quiet, reliable but it is a bit more costly, although it is very powerful.
I'm on the Nova Scotia coast in Canada. I'm pleased that the buoys are in the observations here, but as reported elsewhere they are labeled (ship) but I can easily identify them by number.
If possible in the future with buoys I think it would be very useful to show the wave data to compare with WW3 and the Euro models. In particular; Significant & Max Wave Height, and Dominant Period.
There are a few sources for data around here;

UPDATE: We were having some issue with WMO stations in general, we're sorry about that. Yesterday we fixed the problem so all the named stations are back on the map. Could you please check them as well? Thank you.
