I’ve tried to add some custom cards to my Hass.io setup without success.
Regardless of how I add them (both manually, and also via HACS) I get an error when I try to create a manual card. For example, adding this code:
type: 'custom:monster-card' show_empty: false card: type: entities title: Lights On filter: include: - domain: light state: 'on'
gets me the red error box, with the message:
Custom element doesn’t exist: monster-card.
I’ve done numerous restarts, tried with different custom cards, and have verified that the js is accessible at the path specified in my ui-lovelace.yaml file.
Is there a step that I’m missing?
