Any component that is based on the entity component allows various extra options to be set per platform.

### {% 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` config 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
```
