1. A smart gateway device for providing communications between a first network associated with a building management system (BMS) and a second network associated with a subsystem of the BMS, the smart gateway device comprising:
one or more processing circuits configured to:
discover a physical device on the second network;
receive data comprising a device identifier from the physical device;
generate a new virtual device responsive to a determination that the device identifier does not match any device identifiers in a virtual device registry, the virtual device registry providing mapping between the new virtual device and the physical device, one or more data points of the new virtual device corresponding to one or more data points of the physical device;
receive data values for the one or more data points of the physical device; and
update the one or more data points of the new virtual device with the data values obtained from the physical device, the virtual device configured to represent the physical device on the first network.
