Grouping Wireless Lighting Nodes According to a Building Room Layout
First Claim
1. A method for determining the relative locations of plural wirelessly-controllable building service device nodes (1 . . . 8) and switching control nodes (10, 11) within a building, at least some of the plural building service device nodes being located in different rooms of the building, comprising the steps of:
- establishing wireless communication between the nodes to determine relative spatial positions of selected nodes using received signal strength indication (RSSI) values indicative of a distance of separation between two communicating nodes;
grouping the building service device nodes into two or more groups, a first group (22) corresponding to service device nodes (1 . . . 4, 7, 8) in a first one of said different rooms (13) and a second group (21) corresponding to service device nodes (5, 6) in a second one of said different rooms (12), based on spatial distribution of service device nodes as indicated by the RSSI values; and
allocating the service device nodes of each group to at least one associated switching control node.

Abstract
A method for determining the relative locations of plural wirelessly controllable building service device nodes and switching control nodes within a building. At least some of the plural building service device nodes are located in different rooms of the building and should be allocated to switching control nodes on a room-specific basis. Wireless communication is established between the nodes to determine relative spatial positions of selected nodes using received signal strength indication (RSSI) values indicative of a distance of separation between two communicating nodes. The building service device nodes are then grouped into two or more groups, a first group corresponding to service device nodes in one of said different rooms and a second group corresponding to service device nodes in another of said different rooms, based on spatial distribution of service device nodes as indicated by the RSSI values, which are strongly affected by walls separating the rooms. The service device nodes of each group are then allocated to at least one associated switching control node.

14. Apparatus for allocating plural wirelessly controllable building service device nodes (1 . . . 8) to appropriate switching control nodes (10, 11) within a building, at least some of the plural building service device nodes being located in different rooms of the building, comprising:
-
transceivers for establishing wireless communication between the nodes to determine relative spatial positions of selected nodes using received signal strength indication (RSSI) values indicative of a distance of separation between two communicating nodes; a microprocessor (35) for grouping the lighting nodes into two or more groups, a first group (22) corresponding to service device nodes (1 . . . 4, 7, 8) in a first one of said different rooms (13) and a second group (21) corresponding to service device nodes (5, 6) in a second one of said different rooms (12), based on spatial distribution of lighting nodes as indicated by the RSSI values; and allocation means (36) for allocating the lighting nodes of each group with at least one associated switching control node. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A switching control node (11) for switching wirelessly controllable lighting nodes (1 . . . 8) in a building, and for automatically selecting lighting nodes for allocation to the switching control node where at least some of the plural lighting nodes are located in different rooms (12, 13) of the building, comprising:
-
a transceiver (31) for establishing wireless communication between the nodes to determine relative spatial positions of selected nodes using received signal strength indication (RSSI) values indicative of a distance of separation between two communicating nodes; a microprocessor for grouping the lighting nodes into two or more groups, a first group (22) corresponding to lighting nodes in one of said different rooms (13) and a second group (21) corresponding to lighting nodes in another of said different rooms, based on spatial distribution of lighting nodes as indicated by the RSSI values; and allocation means (36) for allocating the lighting nodes (1 . . . 4, 7, 8) of the first group for operation by at least one associated switching control node and for not allocating the lighting nodes (5, 6) of the second group.
