A method and a device for supervising 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. Other steps are installing at least one second gateway (12´; 32), each of said peripheral wireless nodes (14; 16; 19; 21; 23) being assigned to one of said first gateway (12) and said at least one second gateway (12´; 32), maintaining a supervision timer for each assigned peripheral wireless node (14; 16; 19; 21; 23), transmitting from each of said peripheral wireless nodes (14; 16; 19; 21; 23) a periodic status message,resetting in the gateway said supervision timer when receiving a periodic status message from an assigned peripheral wireless node (14; 16; 19; 21; 23), and reporting from a first gateway to said at least one second gateway an assigned peripheral wireless node (14; 16; 19; 21; 23) as failed when no periodic status message has been received within a predefined time period. The device also comprises at least on remote central monitoring station (22) and timing means in said gateways and said nodes. |
