So that’s why I gave you the link for instructions to put them in configuration.yaml …
Did you look at it?
CONFIGURATION VARIABLES
mode
(string)(Required)
In what mode should the main Lovelace panel be, yaml or storage (UI managed).
resources
(list)(Optional)
List of resources that should be loaded when you use Lovelace. Only use this when mode is yaml . If you change anything here, click the three dots menu (top-right) and click on Reload resources for Lovelace to pick up changes without restarting Home Assistant. You can also call lovelace.reload_resources service directly.
url
(string)(Required)
The URL of the resource to load.
type
(string)(Required)
The type of resource, this should be either module for a JavaScript module or css for a StyleSheet.
Do you know if its possible to add a HACs frontend card to the Dashboard? I’m not using the lovelace-ui.yaml but instead using the UI “Add Card” button. However I can’t find a resource that I downloaded from HACS when I click the “Add Card” button. I do see the JavaScript module resource in the correct folder on my Raspberry Pi though.
