A while ago, I started a project to monitor power usage; you can read about it in my post Arduino: kWh Monitoring (part 1). Recently, I had a new “smart meter” installed, and naturally, I couldn’t let that go unnoticed.
Inspired by a fellow ne2000-event goer http://juerd.nl/site.plp/kwh (dutch site) who made a kwh-meter-meter. I decided to also do something similar with my Arduino as it was just sitting idle in a box waiting for greatness… To do such a project requires aÂ light amount ofÂ electronics experience, although you can probably do it without. If you know…
