An improved system and method are disclosed for receiving sensor readings from one or more devices and processing the readings in real time to create an output. For example, the method may include, for each device, calculating a value based on the sensor readings obtained from the device for which the value is being calculated. Each of the values that satisfies at least one defined parameter is identified. All of the values that satisfy the defined parameter are aggregated to form an aggregated value. A defined action is executed based on the aggregated value. The steps of receiving, calculating, identifying, aggregating, and executing occur in real time without storing the sensor readings, the values, or the aggregated value.
