Now you can send data to Windy using WeeWX. The WeeWX weather system is an open-source platform written in Python. WeeWX is ideal to run on Raspberry Pi.
To send data from your WeeWX you just need to install WeeWX's plugin.
@tomslavkovsky ! This plugin produces an IO error and doesn't seem to install. Any ideas what is going wrong? See screen shot from Raspberry Pi.
