All these solutions that I have seen require you to have your computer
plugged into the monitor.  Since I'm off-grid, my specific aim is to
monitor usage for the least amount of power consumed in the monitoring
process - even plugging in the old laptop to do it just doesn't cut it.
Anybody seen anything like the labjack that can store captured data and
download it on demand?
