plmtools-imeter
I've packaged up a new release of the modified plmtools package for talking to the iMeter. I think the code has diverged from the base plmtools enough to warrant a rebranding, so I'm (uncreatively) naming the fork 'plmtools-imeter'. I've posted a page for the project over on the main site (but for the impatient among you, here's a direct link).
Improvements from the previous release include support for both Revision 1.1 and 1.15 iMeters (thanks to Erik Wile for his detective work regarding that issue) and a variety of other smaller improvements.
A bit over a week ago I presented my research group's recent work on building monitoring using home automation devices at the BuildSys 2011 workshop in Seattle. Our paper on this work ('Exploiting Home Automation Protocols for Load Monitoring in Smart Buildings') was facilitated in part by the plmtools-imeter package.
