You should get hacs (Home assistant community store). Installs custom cards for you and pretty much hand holds you for the configuration.
You’re doing something wrong with the installation. It could be any number of things.
- Wrong location for files
- Wrong files
- Wrong call out for location of files
I suggest moving towards HACS, especially if you are going to be using other custom cards.
So easy, it’s a one button install and includes all the configuration documentation.
