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.][services]
 - [@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])

```yaml
# 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.
