Claim One:
1. A method for non-intrusively monitoring a load including a plurality of appliances, the method comprising: retrieving a plurality of mathematical models, each of the models modeling operation of a respective subset of the appliances; predicting a value of a respective operational parameter for each said subset of the appliances; measuring an output of the load; calculating a respective value of each of the operational parameters, the calculating being based on the mathematical models and the output of the load; repeating the predicting, measuring and calculating steps until a metric pertaining to a difference error between the predicted value and the corresponding calculated value of the operational parameter is equal to or below a threshold for one said subset of the appliances; and deciding that each said appliance in the one said subset of the appliances whose metric pertaining to the difference error is equal to or below the threshold is currently operating.
