post	0.19: Empowering scripts and Alexa	The new release of Home Assistant includes a lot of upgrades to how we handle scripts and make them available in a wide range of new components including automation and alexa.	2016-05-07 11:06:00 -0700	May 7, 2016	Paulus Schoutsen	balloob	true	Release-Notes

This release is big. Until now, our automations and scripts have been very static. Starting today it should all be a bit more dynamic.

Scripts are now available in automations and when responding to Alexa/Amazon Echo. Both of these components will now expose data to be used in script templates (including from_state !). Passing data to script entities is available by passing the data to the script services.

automation:
  trigger:
    platform: mqtt
    topic: some/notify/topic
  action:
    service: notify.notify
    data_template:
      message: {{ trigger.payload }}

automation 2:
  trigger:
    platform: state
    entity_id: light.hue
  action:
    service: notify.notify
    data_template:
      message: {{ trigger.to_state.name }} is now {{ trigger.to_state.state }}

Entity Namespaces allow you to influence the entity ids for a specific platform. For example you can turn light.living_room into light.holiday_home_living_room with the following config:

light:
  platform: hue
  entity_namespace: holiday_home

      name: My DI.0 light device
      packetid: 1b2200000890efab1213f60
