Peckham Power are currently developing a Power Meter project. Anna and Hugo have been testing the kit and now it's my turn. We're testing the AlertMe meter. There are two main components: a small device which clamps (non-invasively) to the cable coming into the house and a base station which wirelessly communicates with the clamp and connects to the broadband modem. The data is sent to AlertMe and then to Google Power Meter which allows you to analyse your consumption and figure out where you can save energy and money.
