Davis vantage Vue
My PWS is a Vantage Vue. I report weather on weather Underground using a weatherlink data logger and 6.0.3 software. Is my weather station supported on windy.com? If so, what must I do since I've tried to join several times?
In your situation I would invest in a Meteobridge Nano. So much more you can then do with your station, not just adding Windy.
But there are other equally interesting options like running Weather-Display, Cumulus MX, or WeeWx which would all also give you a lot more not just Windy.
You have a lot of options to consider. You don't even need to be limited to just one of these options.
