The Cree SmartCast Link device includes a BACnet service that virtualizes BACnet devices. The virtualized BACnet devices represent the lighting zones or spaces in a building. Each space then has a set of BACnet objects that are used to monitor and control the lights for the space. In addition, aggregated BACnet devices that represent the entire floor or building are also available so you can view and control all the lights in all spaces on the entire floor or building. This allows for easier monitoring and control with less programming logic in Metasys.

See the following table for the BACnet object list provided by Cree.

Lighting level Analog value Set the brightness of the lights from 0% to 100%. Read and write
Space occupied Binary value Whether or not the space is occupied; based on movement detected by the PIR occupancy sensor included with each luminaire. Read only
Space occupied % Analog value Percentage of lights in a space that reported occupancy event; based on movement detected by the PIR occupancy sensor. Can translate to the percentage of the space that is occupied. Read only
