It is an essential feature of the present invention that the control unit always connects to the data center and that the control unit cannot be directly connected to for preventing unauthorized access to the control unit .When the homeowner accessing the control page enters a “REQUEST, “COMMAND”, or “ORDER” the data center sends a “connect” command to the control unit . If online, the control unit will then establish a direct connection with the data center thereby allowing the control unit to connect only to the authorized data center and not an unauthorized party.
