post	0.15: Unforked Open Z-Wave, templated service calls, extended scene support and PEP257 compliance.	Home Assistant 0.15 has arrived.	2016-03-12 10:55:00 -0800	March 12, 2016	Paulus Schoutsen	balloob	true	Release-Notes

Two weeks has past so here is 0.15! We have been focussing a lot on quality. Making sure the system is more stable and reliable. I usually try to highlight one cool thing in the release notes but this release has 4 exciting announcements!

• @fabaff has upgraded the codebase to follow the PEP257 documentation standard.
• @partofthething has migrated us to use the main Python Open Z-Wave library instead of our forked version.
• To make our automations more powerful, @persandstrom added the option to use templates to dynamically create service calls. This works for automation, Alexa, universal media player, template switch. Learn more.
• @MartinHjelmare has upgraded our scene support to now support all built-in services and components.

Besides bug fixes, this release also brings:

• Scene: Converted to a platform based component (@sander76)
• Scene: Hunter Douglas Powerview now supported (@sander76)
• Lock: MQTT platform added (@fabaff)
• Device Tracker: OwnTracks will allow filtering inaccurate GPS locations (@HydrelioxGitHub)
• Binary Sensor: Wemo Motion now supported (@pavoni, @ryanlaux)

# Example using templates for service and data in service call.
# Works for automation, Alexa, universal media player, template switch.
automation:
  - trigger:
      - platform: state
        entity_id: switch.bathroom
    action:
      service_template: >
        {% raw %}{% if is_state('switch.bathroom', 'on') %}
          switch.turn_on
        {% else %}
          switch.turn_off
        {% endif %}{% endraw %}
      data_template:
        entity_id: switch.{% raw %}{{ states('input_select.is') }}{% endraw %}

Breaking Changes

• Media Player: Attributes to call service play_media has been renamed to media_content_type and media_content_id, to match the corresponding media player state attributes. This change affects automations, scripts and scenes.
