Hello friends!
I’d like to throw my own data forwarding project into the ring. I’ve been using it for a couple of years and it’s pretty battle-tested at this point.
https://github.com/leoherzog/WundergroundStationForwarder
This is open-source code built to be run on the free Google Apps Script platform, no local hardware or internet connection required. It automatically takes readings from your weather station's API and forwards them on to any services you choose, including Windy and CWOP. Take a look, and feedback welcome!
