{
        module: 'MMM-NetworkScanner',
        position: 'top_left', 
        config: {
            devices: [
                    { ipAddress: "github.com", name: "Github", icon: "globe"},
                    { macAddress: "1a:1b:1c:1a:1b:1c", name: "Server", icon: "server"},
                    { macAddress: "2a:2b:2c:2a:2b:2c", name: "Desktop", icon: "desktop"},
                    { ipAddress: "10.1.1.10", name: "Laptop", icon: "laptop"},
                    { macAddress: "4a:4b:4c:4a:4b:4c", name: "Mobile", icon: "mobile"},
                ],
            showUnknown: false,
            showOffline: true,
            keepAlive: 300,
            updateInterval: 5
            residents: "Mobile",
            occupiedCMD: {notification: 'REMOTE_ACTION', payload: {action: 'MONITORON'}},
            vacantCMD  : {notification: 'REMOTE_ACTION', payload: {action: 'MONITOROFF'}},

        }
