Even if the Windy API key were smaller you still would not be able to upload to Windy with your Ecowitt console using the "Customized" server upload feature because it uploads using a different protocol than what Windy uses.

My suggestion for you is to use the Ecowitt GW1000 or Froggit DP1500 in conjunction with your station if you don't currently have one of these. It will be compatible with your current station as long as you get it with the same frequency as your current station (433, 868, or 915 MHz).

Then you can run one of the follow software applications that are capable of getting data from the GW1000 / DP1500 and uploading it to Windy. These compatible applications are: Cumulus MX, Meteobridge, Weather-Display, and WeeWX. A good solution to run these is a Raspberry Pi. If you need more guidance you should head over the wxforum.net and read up on these solutions or ask for help there.

This is not really surprising. This weather station is a Personal Weather Station (pws). Some of them give bad figures but Windy cannot delete them.
Weather stations labelled madis and pws are non official weather stations.

Hello, what is your station ID please?

@gkikas-lgpz Your explanation made sure that there is a problem in values conversation as the airports weather stations always show the value 7 Km/h instead of 6 Km/h, so the weather stations is not the problem.

@korina

All fine now, thanks.

@stratus13 Hello, thank you for your report. We know about this issue and we plan to update our database in the future.

@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.
