Some components or platforms (those that are based on the entity class) allows various extra options to be set.
By setting an entity namespace, all entities will be prefixed with that namespace. That way
light.bathroom can become
# Example configuration.yaml entry light: platform: hue entity_namespace: holiday_house
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.
# Example configuration.yaml entry to poll Hue lights every 10 seconds. light: platform: hue scan_interval: 10
