1. A method of identifying a sensor signature indicative of an operative state of a device, the method comprising:

  • providing a plurality of sensors in a training space, each sensor operable to measure a different characteristic;

    determining the values of one or more attributes of the training space;

    receiving a plurality of sensor signals, each sensor signal indicative of a different characteristic measured by one of the plurality of sensors in the training space;

    receiving device operation information comprising the type and operative state of a device in the training space;

    determining, from the received plurality of sensor signals and the received device operation information, a sensor signature comprising values of a combination of different measurable characteristics that are indicative of an operative state of the device;

    associating the determined sensor signature with the determined values of the one or more attributes of the training space; and

    storing the determined sensor signature together with the associated values of the one or more attributes.
