## Changing the entity ID
|
|
|
|
You can use the UI to change the entity ID and friendly name of supported entities. To do this:
|
|
|
|
1. Select the entity, either from the frontend or by clicking the info button next to the entity in the Developer Tools "States" tab.
|
|
2. Click on the cog icon in the right corner of the entity's dialog
|
|
|
|
3. Enter the new name or the new entity ID (remember not to change the domain of the entity - the part before the `.`)
|
|
|
|
4. Select *Update*
|
|
|
|
If your entity is not supported, or you cannot customize what you need via this method, please see below for more options.
|
|
|
|
## Customizing entities
|
|
|
|
By default, all of your devices will be visible and have a default icon determined by their domain. You can customize the look and feel of your front page by altering some of these parameters. This can be done by overriding attributes of specific entities.
|
|
|
|
### Possible values
|
|
|

### Manual customization
|
|
|
|
<div class='note'>
|
|
|
|
If you implement `customize`, `customize_domain`, or `customize_glob` you must make sure it is done inside of `homeassistant:` or it will fail.
|
|
|
|
</div>
|
|
|
|
```yaml
|
|
homeassistant:
|
|
name: Home
|
|
unit_system: metric
|
|
# etc
|
|
|
|
customize:
|
|
# Add an entry for each entity that you want to overwrite.
|
|
thermostat.family_room:
|
|
entity_picture: https://example.com/images/nest.jpg
|
|
friendly_name: Nest
|
|
switch.wemo_switch_1:
|
|
friendly_name: Toaster
|
|
entity_picture: /local/toaster.jpg
|
|
switch.wemo_switch_2:
|
|
friendly_name: Kitchen kettle
|
|
icon: mdi:kettle
|
|
switch.rfxtrx_switch:
|
|
assumed_state: false
|
|
media_player.my_media_player:
|
|
source_list:
|
|
- Channel/input from my available sources
|
|
# Customize all entities in a domain
|
|
customize_domain:
|
|
light:
|
|
icon: mdi:home
|
|
automation:
|
|
initial_state: "on"
|
|
# Customize entities matching a pattern
|
|
customize_glob:
|
|
"light.kitchen_*":
|
|
icon: mdi:description
|
|
"scene.month_*_colors":
|
|
icon: mdi:other
|
|
```
|
|
|
|
### Reloading customize
|
|
|
|
Home Assistant offers a service to reload the core configuration while Home Assistant is running. This allows you to change your customize section and see your changes being applied without having to restart Home Assistant.
|
|
|
|
To reload customizations, navigate to Developer Tools > YAML and then press the "Reload Location & Customizations" button. If you don't see this, enable Advanced Mode on your user profile page first.
|
|
|
|
You can also use the [Quick bar](/docs/tools/quick-bar/#command-palette), and choose "Reload Location & Customizations".
|
|
|
|
Alternatively, you can reload via service call. Navigate to Developer Tools > Services tab, select `homeassistant.reload_core_config` from the dropdown and press the "Call Service" button.
|
|
|
|
<div class='note warning'>
|
|
New customize information will be applied the next time the state of the entity gets updated.
|
|
</div>
