Some components or platforms (those that are based on the [entity](https://github.com/home-assistant/home-assistant/blob/dev/homeassistant/helpers/entity.py) class) allows various extra options to be set.
|
|
|
|
### {% linkable_title Entity namespace %}
|
|
|
|
By setting an entity namespace, all entities will be prefixed with that namespace. That way `light.bathroom` can become `light.holiday_house_bathroom`.
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry
|
|
light:
|
|
platform: hue
|
|
entity_namespace: holiday_house
|
|
```
|
|
|
|
### {% linkable_title Scan Interval %}
|
|
|
|
Platforms that require polling will be polled in an interval specified by the main component. For example a light will check every 30 seconds for a changed state. It is possible to overwrite this scan interval for any platform that is being polled by specifying a `scan_interval` configuration key. In the example below we setup the Philips Hue lights but tell Home Assistant to poll the devices every 10 seconds instead of the default 30 seconds.
|
|
|
|
```yaml
|
|
# Example configuration.yaml entry to poll Hue lights every 10 seconds.
|
|
light:
|
|
platform: hue
|
|
scan_interval: 10
|
|
```
