My name is Radoslav, my PWS WH 2080 is located in Vyškov, Czech Republic. The data is processed by WeeWX on its own server and displayed on http://www.pocasi-kucerov.cz/weewx/sofa/
The data are further reported on WU, AWEKAS, WOW Metoffice and PWSWeather. WeeWX also creates "realtime.txt" (Cummulus SW) and "gauge-data.txt" (SteelSeries Gauges) every minute, and these are available immediately.
WeeWX contains several uploaders, others can be easily added (more than 20 - see https://github.com/weewx/weewx/wiki).
The author of the SW is very helpful and I think that if you turn to him (http://www.weewx.com/), he likes to create another for Windy according to your requirements.
Of course I agree with the sharing of my PWS data.
If you are interested, contact me.
