Device search

To obtain a list of available devices on the local network UDP broadcast packets are used. After connecting to the network several times per minute, each device sends a UDP packet to port 23500 with JSON data like:

{
        "sn":"058016000543464839373520000159",
        "hw":"ax",
        "cloud":"true",
        "connection":"cloudCon",
        "wifi":"-71",
        "display":"23.0"
}
