However, there must ...Great blog post (as always!)<br /><br /><em>However, there must be other data sets that can offer insight for energy disaggregation systems, even if they only contain aggregate data.</em><br /><br />I expect you already know this but, if not: Cosm contains a fair amount of aggregate power data. A <a href="https://cosm.com/feeds?q=power" rel="nofollow">search for "power" on Cosm</a> produces 2076 results. I have no idea what proportion of those feeds contain useful data! I believe it's fairly trivial to write a script to pull all those feeds onto your own machine, but I haven't done it myself. I imagine it could be quite time consuming to figure out which feeds are useful and which aren't (but if you do figure that out then please consider sharing your findings!)<br /><br />For a few months last year I monitored my home's aggregate power consumption, and some individual appliances, and a bunch of temperatures. Some of those data are on Cosm <a href="https://cosm.com/users/jack_kelly" rel="nofollow">here</a> and some are on github <a href="https://github.com/JackKelly/domesticPowerData" rel="nofollow">here</a>. That's pretty crappy data though (not least because the CC IAMs I used often had long "blackouts" lasting an hour or two, which is what drove me to build <a href="http://jack-kelly.com/summary_of_my_energy_monitoring_code" rel="nofollow">my own power measurement kit</a>).<br /><br />For the past few months I've been collecting power data from my own home. Last night I added the last 5 IAMs. I'm now logging 51 channels (!) including every appliance and the lighting circuit. I'm recording whole-home voltage and current waveforms at 16kHz (from which the system calculates active and apparent power once a second) as well as whole-home apparent power recorded using a standard home energy monitor CT clamp. I plan to release this dataset soon, along with smaller datasets recorded from a small number of MSc student homes. At release, this dataset certainly won't be as comprehensive as REDD but hopefully it'll add some variety, and I plan to continue to pester my MSc students to install more IAMs this year so we get more coverage of their home appliances ;)<br />Jack Kellyhttps://www.blogger.com/profile/14542966078686299001noreply@blogger.com
