Hi Edouard,
Thanks for the prompt reply. Since I had also reached out to support at the same time as posting here I now know not to expect something soon.
FYI, Although I use many other languages, I've not done much with objective-c. However, using chatGPT4 to modify the example plugin included in the Weathercat SDK distribution is crazy easy! I basically asked it to modify the application to instead of generating the text file, upload the Weather values to Windy.com and gave it a link to the Windy.com upload instructions. A few tweaks later and it was ready to try. Unfortunately I don't know how to actually install the plugin for the current version of Weathercat.
