Config Editor Card to edit configuration.yaml from dashboard

Installation

Manually add config-editor-card.js to your <config>/www/ folder and add the following to the configuration.yaml file:

lovelace:
  resources:
    - url: /local/config-editor-card.js?v=1
      type: module

OR install using HACS and add this (if in YAML mode):

lovelace:
  resources:
    - url: /hacsfiles/config-editor-card/config-editor-card.js
      type: module

The above configuration can be managed directly in the Configuration -> Lovelace Dashboards -> Resources panel when not using YAML mode, or added by clicking the "Add to lovelace" button on the HACS dashboard after installing the plugin.

Configuration

You will also need to install a custom component https://github.com/htmltiger/config-editor

edit configuration.yaml and add the following so it can load

config_editor:

It is also possible to add this using + Add Card UI and choose Custom: Config Editor Card
