Wattom: Ambient Eco-feedback with Mid-air Input
  This paper presents Wattom, a highly interactive ambient eco-feedback smart plug that aims to promote a more sustainable use of electricity in the home. This paper describes our latest implementation of the Wattom plug, and three system applications. The first enables Wattom to power a connected device , and provide real-time feedback on the amount of electricity in the grid from renewable sources. The second enables users to schedule power events from their smart watches. Finally, the third application uses non-intrusive load monitoring (NILM) to provide users with personal consumption information on multiple devices connected to a single Wattom plug. The paper concludes by presenting insights into the development and use of various iterations of the Wattom plug.
