OT: advise about energy consumption logging at the plug

Your facility has a watt-hour meter that you can read and record manually.

For single devices or wall outlets, the simplest measurement is probably a kill-a-watt or one of its clones.This will record energy consumed since a last buttom-press or application of input power.

First order approximation for real datalogging is a record of current, stored on a portable PC. Multimeters with PC interface are becoming fairly inexpensive, to make this measurement - software to record and manipulate data may be slightly buggy or poorly supported.

Haven't seen a really cheap datalogger, but haven't looked lately. These will also mant to interface to a PC for data recording analysis and display.

I did notice it. Has not had messages in at least 5000 days. But I can post there and see if anyone notices.

The group's not quite that dead, but it is quiet. I suggested it because consumption is a reltively big issue in off-grid situations and folks might be lurking who have useful experience or ideas.

Posted there. Let’s see how it goes.

Thanks. Moving discussion to alt.energy.homepower where I posted a more complete description of my small problem.
