@gar37bic Following up, looking at the docs, it appears that the process might be as follows:
- Use the web server on your Raspberry Pi or other HA server, or any web server on your home LAN
- Add a web page in that local website and follow the instructions for setting up the embedded Windy API - this includes the Leaflet and Windy API libraries. This looks like the hard part.
- Use the WebPage card in HA / Lovelace or whatever front end you use to add a card with that local web page.
I have not done this yet, we shall see if I can get it working.
