MQTT, Rasperry Pi, Logitech Squeezebox and ASUSWRT routers now supported

It’s time for the August release and there is some serious good stuff this time. The core of Home Assistant has gone some serious clean up and a bump in test coverage thanks to @balloob. If you’re a developer, make sure you read up on the deprecation notices. @fabaff did another great round of documenting all the various components.

MQTT Support The big new addition in this release is the support for the MQTT protocol by @fabaff with some help from @balloob. It will now be possible to integrate any IoT device that talks via MQTT. For the initial release we support connecting Home Assistant to a broker (no TLS yet). Components can now subscribe and publish to MQTT topics (see the example) and also support for the automation component has been added. For more information, see the MQTT component page.

# Example configuration.yaml entry
mqtt:
  broker: IP_ADDRESS_BROKER
  # All the other options are optional:
  port: 1883
  keepalive: 60
  qos: 0
  username: your_username
  password: your_secret_password

Raspberry Pi GPIO Support @gbarba has contributed support to use the general purpose input and output pins on a Raspberry Pi as switches inside Home Assistant.
