SmartMeter

My house has a PG&E smartmeter electronic power meter. I use [smartermeter|https://github.com/mcolyer/smartermeter] to extract my power usage from the PG&E website. Then smartermeter uploads the data to [pachube|http://www.pachube.com], a service that allows you to connect various data sources to the internet and make graphs and such. I guess it's sort of a data brokerage. Anyway, here's the result. First, usage for the last three days: <<RawHtml <img src="https://api.pachube.com/v2/feeds/47488/datastreams/meter.png?width=730&height=250&colour=%23004BA6&duration=3days&legend=kwH&title=My%20Power%20Usage&stroke_size=4&show_axis_labels=true&detailed_grid=true&scale=manual&min=o&timezone=PST" alt="My Home Power Usage, in kwH" title="My Home Power Usage, in kwH"> >> For the last week: <<RawHtml <img src="https://api.pachube.com/v2/feeds/47488/datastreams/meter.png?width=730&height=250&colour=%23004BA6&duration=1week&legend=kwH&title=My%20Power%20Usage&stroke_size=4&show_axis_labels=true&detailed_grid=true&scale=manual&min=o&timezone=PST" alt="My Home Power Usage, in kwH" title="My Home Power Usage, in kwH"> >> For the last month: <<RawHtml <img src="https://api.pachube.com/v2/feeds/47488/datastreams/meter.png?width=730&height=250&colour=%23004BA6&duration=1month&legend=kwH&title=My%20Power%20Usage&stroke_size=4&show_axis_labels=true&detailed_grid=true&scale=manual&min=o&timezone=PST" alt="My Home Power Usage, in kwH" title="My Home Power Usage, in kwH"> >> And the last two months: <<RawHtml <img src="https://api.pachube.com/v2/feeds/47488/datastreams/meter.png?width=730&height=250&colour=%23004BA6&duration=2months&legend=kwH&title=My%20Power%20Usage&stroke_size=4&show_axis_labels=true&detailed_grid=true&scale=manual&min=o&timezone=PST" alt="My Home Power Usage, in kwH" title="My Home Power Usage, in kwH"> >> The above results are accurate to about an hourly resolution I think. Note that if for some reason my vps crashes and I forget to restart smartermeter you will just see a flat line. I should fix that. Also this page does not automatically reload so you need to refresh if you want to see the latest data.
