UMASS Smart* Home Data Set

Although not collected specifically for energy disaggregation, the Smart* (Smart Star) data set provides power data from 3 thoroughly sub-metered real households. The granularity of data collected for circuit level monitors (premises aggregate and individual circuits) is one reading per second, while individual plug loads are measured roughly every few seconds. Each house contains 21-26 circuit meters and almost all appliances are measured using plug meters.

The data is available for download from the UMassTraceRepository. At the moment, aggregate, circuit and appliance data is available for house A, but only aggregate data is available for houses B and C. I've also updated my post on Public Data Sets for NIALM.

Internship at PlotWatt

Three days ago I started a two month internship at a North Carolina startup called PlotWatt. PlotWatt is a fast growing software company focusing specifically on NIALM technology, with the target of reducing people's energy consumption and therefore saving money on their bills. The core principle of following algorithm development through to deployment to real users is what has driven my interest in the company, and I'm looking forward to contributing to their live NIALM systems over the summer.

Although this means I might not be posting so many details about the technical solutions I'm working on, I'm sure it'll open my mind up to a whole range of challenges I hadn't come across during my PhD. I'm planning to get back to my studies in October, so business should resume as normal around then.
