1. A method for detecting remote network devices in a network by a network control device in communication with one or more remote network devices, comprising:

  • detecting an event by the network control device;

    in response to detecting the event;

    a) transmitting a message by the network control device, the message requesting a response from any remote network devices that have not previously communicated with the network control device comprising a first network identification code that identifies a first network controlled by the network control device;

    b) determining whether a response to the message has been received by the network control device, the response transmitted by a remote network device after receiving the message and determining that the first network identification code matches a second network identification code stored within the remote network device, the response comprising identification information of the remote network device;

    c) if a response has not been received;

    terminating the method for detecting remote network devices if a pre-determined time period has elapsed since transmitting the message;

    d) if a response has been received;

    storing identification information associated with the responding remote network device; and

    repeating steps a-d until no further responses are received.
