SpaceDevices

Gets the current active mac/IP combination from our wifi access points via mqtt (sessionTopic). Has a global database (masterFile) and a user customizable database (userFile). The last one is changeable via a web interface. Any client can only change the entry for its current mac address.

As result an json string is sent via mqtt (devicesTopic), e.g.:

{  
  "people":[  
    {  
      "name":"Hans",
      "devices":[  
        {  
          "name":"Handy",
          "location":"Space"
        },
        {  
          "name":"Thinkpad",
          "location":"Space"
        }
      ]
    },
    {  
      "name":"Jon",
      "devices":[  
        {  
          "name":"Handy",
          "location":"Space"
        },
        {  
          "name":"Mac",
          "location":"Space"
        }
      ]
    }
  ],
  "peopleCount":8,
  "deviceCount":38,
  "unknownDevicesCount":18
}
