I am writing to make sure, as I understand it, I cannot send data from Ecowitt weather station to windy.com by filling in the form in the Customized uploading window?
The GW1000 cannot itself upload to Windy.com. The Windy.com upload API is different and not supported by the "Customized" server upload feature.
I present to you 2 options:
1- Add some additional weather software that supports uploading to Windy.com like; Cumulus MX, Meteobridge, Weather-Display, or WeeWX
2- Upload to CWOP, which is also not directly supported by the GW1000...which means again referring to my #1 option. But any CWOP station once registered shows up on Windy.com. There are some scripts out there if you search for doing things like pulling from WU to the upload to CWOP...but eh...go with option #1.
