Smart power meter interface for the Linux crowd

[Graham Auld] got his hands on an energy monitor for free from his utility company. The device seen in the insert provides a nice LCD display but he wanted a way to graph the data over time. There was an included cable and a method of using Google PowerMeter but only for Windows computers. He did a little poking around and came up with a Perl script to interface the meter with Google’s tools.

The hardware module is known as the Current Cost CC128 and the developer was nice enough to publish an XML output description which [Graham] used in his script. From there it’s just a matter of registering and authenticating through the Google PowerMeter API. The script is not fully polished yet but it serves as a road map for your own implementation.
