  homeassistant.components.light.vera
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  Support for Vera lights. This component is useful if you wish for switches
  connected to your Vera controller to appear as lights in Home Assistant.
  All switches will be added as a light unless you exclude them in the config.
  
  Configuration:
  
  To use the Vera lights you will need to add something like the following to
  your configuration.yaml file.
  
  light:
    platform: vera
    vera_controller_url: http://YOUR_VERA_IP:3480/
    device_data:
      12:
        name: My awesome switch
        exclude: true
      13:
        name: Another switch
  
  Variables:
  
  vera_controller_url
  *Required
  This is the base URL of your vera controller including the port number if not
  running on 80. Example: http://192.168.1.21:3480/
  
  device_data
  *Optional
  This contains an array additional device info for your Vera devices. It is not
  required and if not specified all lights configured in your Vera controller
  will be added with default values. You should use the id of your vera device
  as the key for the device within device_data.
  
  These are the variables for the device_data array:
  
  name
  *Optional
  This parameter allows you to override the name of your Vera device in the HA
  interface, if not specified the value configured for the device in your Vera
  will be used.
  
  exclude
  *Optional
  This parameter allows you to exclude the specified device from Home Assistant,
  it should be set to "true" if you want this device excluded.
