Claim Text:
1. A method for determining the relative locations of a plurality of nodes within a building, the nodes including a plurality of wirelessly-controllable service device nodes and a plurality of switching control nodes, at least some of the service device nodes being located in different rooms of the building with respect to each other, the method comprising: establishing wireless communication between the nodes to determine relative spatial positions of the nodes using received signal strength indication (RSSI) values each indicative of a distance of separation between two of the nodes; grouping the service device nodes into at least two groups, including a first group of the service device nodes located in a first one of said different rooms, and a second group of the service device nodes located in a second one of said different rooms, based on a spatial distribution of the nodes as indicated by the RSSI values; and allocating the service device nodes of the first group to have a switching operation thereof controlled by a first of the switching control nodes, and allocating the service device nodes of the second group to have a switching operation thereof controlled by a second of the switching control nodes.
