I'm creating an online power monitoring system so you can see how your home or office uses power. A web platform is great for this because we can centralise the processing / graph generation and analysis and then put simple, cheap devices into people's buildings to do the actual measurement.

We offer live data (updated every second while you watch) and multiple channels, all at a price that is cheap for a solution like ours.
