We just published a paper on energy consumption end-use disaggregation using Hidden Markov Models and Dynamic Time Warping. This is part of the research we are conducting on smart metered data analytics and modelling. The work has been supported by the SmartH2O project. More details and the full paper are available here (free access until Dec, 31, 2016!).
