Abstract: A method of synchronizing state information of a home wireless system wherein the home wireless system comprises a plurality of peripheral wireless nodes (14; 16; 19; 21; 23) and a first gateway (12) having wireless communication means for communicating with and controlling associated peripheral wireless nodes, the method comprising the steps installing at least one second gateway (26) in said home wireless system, assigning peripheral wireless nodes to said first gateway (12) or anyone of said at least one second gateway (12?), and each gateway directing each assigned peripheral wireless node to communicate with an assigned gateway, receiving in a first gateway system state affecting input message from an associated peripheral wireless node, determining in said first gateway a resulting system state based on said input, and communicating said resulting system state as a state change message from said first gateway to said at least one second gateway.

Abstract: A method of handling inconsistencies in a home wireless system wherein the home wireless system comprises a plurality of peripheral wireless nodes (14; 16; 19; 21; 23), a first gateway (12) having wireless communication means for communicating with and controlling associated peripheral wireless nodes, at least one second gateway (12?; 32), and a Remote Central Monitoring Station, RCMS.
