AbstractA home automation system is provided that has addressable input modules and sensors that provide input signals relating to at least one of the condition of the input modules or a sensed condition, an interface coupled to the input modules and sensors to receive and transmit the input signals and control signals, and a computer coupled to the interface and which receives the input signals from the interface and transmits the control signals to the interface. The computer receives the input signals from the interface, determines which rules of a stored set of rules are dependent on the input values, produces output values in accordance with those rules that are determined to be dependent on the input values, with at least one such rule producing output values via an arithmetic operation having more than two distinct values, generates control signals as a function of the output values, and transmits the control signals to the interface. Addressable output modules are coupled to the interface and receive the control signals from the interface. The addressable output modules perform a specified action in accordance with the control signals.
