Entity cards show error when manually adding “state_color”.
Expected a value of type undefinedforstate_colorbut receivedtrue.
Must be removed to utilize visual editor. Color state is functional. Suspect bug on frontend.
This is not a bug or an error.
The graphical UI simply does not support defining state_color.
So you get a warning and have to use the code editor.
There are many valid card options not yet supported.
I’m getting the same error message but I’m unsure as to which yaml file I need to edit. Didn’t find anything in configuration.yaml so I wonder where the code for a lovelave dashboard is.
Just starting out on HA so steep end of the learning curve
