I made a Tweet-A-Watt last year which is a hacked Kill-A-Watt wall plug that sends data wireless to a computer. The twitter API has changed a lot since then, it now uses OAuth to authenticate tweets. I cloned ladyada’s Tweet-A-Watt github repo and started getting to work. My code isn’t ready to push up to the community yet but data is flowing.
Currently using 390 Watts, 28196 Wh today so far
