I need help how can sent data to windy with API key
I have a sainlogic ws3500 weatherstation
@maxi2019 You need to purchase additional hardware and then run additional software that will support uploading to Windy.
The first thing you need is an Ecowitt GW1000. This is compatible with your station and it will pick up your sensors.
Then you can run one of several software. Cumulus MX, Meteobridge, Weather-Display, or WeeWX. All of these software support uploading to Windy.
