Improve This Backbone "Query"

awful.js

// A home has floors. 
// A floor has rooms. 
// A room has device groups.
// A device group has devices.
// A device has addresses.
// An address has actual address value.
//
// So, the purpose of this awful mess is to say :
// "give me every device with this address, from any home"
//
// This is first thing I could come up with that works. But I know it's
// an awful mess. I'd really like to clean it up. 
//
// Suggestions, other than use a database?
//
// The data is in a .json file, and I do not have the option of using a database.

  Home = Backbone.Model.extend({

    // other stuff here
    // ...

    findDevicesByAddress: function(address){
      var devices = new HIT.DeviceCollection();
