Auto-discovery of smart meter update interval

Abstract

A control device is connected to a smart meter. The control device includes a communication engine configured to retrieve an energy consumption value from a measuring unit coupled to the smart meter based on a polling interval. The control device includes a discovery engine operatively coupled to the communication engine and configured to discover an update interval of the smart meter by increasing the polling interval iteratively from an initial value until a difference is detected between successively retrieved energy consumption values. Furthermore, the device includes a user interface engine, operatively coupled to the discovery engine and the communication engine, configured to estimate a utility consumption at a present time based on the difference value and the polling interval.
