The document discusses the Internet of Things (IoT) and its impact on smart energy through low-powered, network-connected devices, particularly emphasizing the use of Arduino for development. It highlights the importance of measurement in energy management and introduces local smart energy solutions, including the SEGmeter and SEGshield, which utilize Arduino technology. The Melbourne Hackerspace offers workshops and collaboration opportunities for those interested in building their own smart meters.
