Developments of the in-home display systems for residential energy monitoring

In order to efficiently reduce the amount of electricity usage in residential areas, the demand response (DR) of consumers is of importance. The in-home display (IHD) system provides energy monitoring information for the consumer DR. Considering the building structures and the existing automatic meter systems, several types of IHD systems have recently been developed based on the 2.4 GHz ZigBee radio, the power line communication technique, and the sub 1-GHz narrow-bandwidth radios. In this paper, five cases of IHD system developments and implementations are introduced and their technologies including network architectures compared¹.
