remote electrical monitor (web based)

Try looking at Emon or PML metering. Sorry to say sags and surges will require some capture circuits and that is going to increase the price.

Check out Kep ware for your I/O server. Or look for a modbus output .

It may be better to re-post in a week or so - when people are back at work and not being dragged by their husbands to look at new cars...unless things are different in the US?

I haven't seen anything that matches your description. If I had that problem, I would probably use an old computer (probably a laptop) with a suitable operating system (Linux or Msoft) running on a floppy or, better, a flash drive. The software to interface to standard test equipment monitoring the lines will be pretty simple - just a few dozen lines of code at most..

Some of the PML devices may meet this requirement, although it may be through its programming/server software package. Most of the devices come preprogrammed with all of your general metering, but require the software to modify the device.

If remember right the 4 yr old versi>Seasons Greetings to all!

Yeap, I'd go with E-Mon. They should have something of that species in there monitoring devices.

Goodluck & Happy Holidays.
