+ *platform (required): This must be "MiLight", and refers to the name of the accessory as exported from this file
+ *name (optional): The display name used for logging output by Homebridge. Best to set to "MiLight"
  *ip_address (optional): The IP address of the WiFi Bridge. Default to the broadcast address of 255.255.255.255 if not specified
  *port (optional): Port of the WiFi bridge. Defaults to 8899 if not specified
- *zone (required): The zone to target with this accessory. "0" for all zones on the bridge, otherwise 1-4 for a specific zone
- *type (required): One of either "rgbw", "rgb", or "white", depending on the type of bulb being controlled
+ *type (optional): One of either "rgbw", "rgb", or "white", depending on the type of bulb being controlled. This applies to all zones. Defaults to rgbw.
  *delay (optional): Delay between commands sent over UDP. Default 30ms
  *repeat (optional): Number of times to repeat the UDP command for better reliability. Default 3
+ *zones (required): An array of the names of the zones, in order, 1-4. Use null if a zone is skipped. RGB lamps can only have a single zone.
 
 Tips and Tricks:
  *Setting the brightness of an rgbw or a white bulb will set it to "night mode", which is dimmer than the lowest brightness setting

 TODO:
- *Probably convert this module to a platform that can configure an entire bridge at once, just passing a name for each zone
  *Possibly build in some sort of state logging and persistance so that we can answswer HomeKit status queries to the best of our ability
