System and method for commissioning mesh network-capable devices within a building automation and control system
A commissioning system and method that applies a design configuration, representative of a building automation and control system, to a mesh network of network-capable devices. A cloud-based server system works in concert with an installing device, such as a smartphone or tablet, to apply the relevant configuration of scenarios and spaces, as defined in the design configuration during a design phase, to each mesh node in the mesh network. The commissioning system first transforms the defined scenarios and spaces, which essentially represent a logical configuration of the building automation and control system, into a network-centric configuration. Then, the system decomposes the network-centric configuration into a physical configuration of each mesh node, resulting in a set of parameters for each mesh node. The commissioning system then transmits the set of parameters, including one or more group addresses, to the applicable mesh node, for each affected mesh node in the network.
