Design guidelines for smart appliances

Embedded intelligence can help controlling and reducing the energy consumption of appliances to a significant amount. Such a smart appliance will consist of a communication interface, a local processing and decision unit and the appliance's actual function. Sophisticated functions for such a device will involve a notion of real-time with a respective time format, a generic database that contains energy usage logs, error messages, warnings and real-time measurements for power usage, and an embedded self-description that allows to integrate the device into a system with minimum manual configuration. While there exists concepts for smart plugs and smart outlets that can be applied to “smarten” an existing device, in general we need to assume that the variety of appliances and technologies will require the support for various architectures including software solutions that integrate into the functions of an appliance with existing computing power, e.g. a DVD player or a state-of-the-art television set. Thus there is a need for architectural services with flexibility for different hosting systems while keeping the interoperability with respect to a smart home control system.
