I read the documentation it says “Weather icons can be overwritten with your own personal images via a Theme” but it’s not working
please, someone, help me

weather icons: --weather-icon-exceptional: url("local/cloud.png")

url(“local/cloud.png”) Local is your www directory in your config area. And you have to put in the information in the theme you are using.

did you find any solution to this issue? I have the same in a brand new Rpi with HA installed in venv

Meteorologisk institutt (Met.no) integration for weather works well with all icons showing up correctly.
