Abstract
A smart gateway device for providing communications between multiple networks associated with a building management system (BMS). The device includes a first network interface circuit in communication with a first network associated with a building management system (BMS). The device further includes a second network interface circuit in communication with a second network associated with a subsystem of the BMS, wherein the second network is not compatible with the first network. The second network interface circuit is configured to detect a physical device associated with the second network, and to receive a data packet associated with the physical device. The data packet is transmitted to the first network interface circuit. The first network interface circuit is configured to receive the data packet and to generate a virtual device based on the received data packet. The virtual device is configured to represent the physical device on the first network.
