The killawatt device just displays accumulated power use and wouldn't provide any kind of histogram. The more expensive device has a USB interface and an accompanying program to record and display power usage. The included program only runs on Windows but presumably if the USB port data could be monitored on a Linux system something similar could be created. -Alex P.S. To come up with meaningful power usage for UPS sizing you would want to drive the load as hard as possible. > > And, does anyone know of something like this that measures 220VAC as > well?
