The icons will be available under the bha namespace, eg bha:floor-lamp
There is no need to restart.
The steps above will make the icons available, but limited to the Lovelace UI only. If you want the icons to be available throughout Home Assistant, add the following to the frontend
section of your configuration.yaml
frontend:
extra_module_url:
- /hacsfiles/hass-bha-icons/hass-bha-icons.js
For this step, a system restart is needed.
