Added Power-Mate and Power-Mate Lite to the mains power meters available in NZ page. The Power-Mate is more or less a professional instrument of sufficient quality and accuracy for use by home energy auditors, and the Lite version is also pretty damn good. Measurement down to 0.01W and a host of useful features. At time of writing looks like a serial interface version of the professional model for connection to a computer and software for it is in progress but not yet available.
