Just started the project to monitor power usage for the house.
Bought the Raspberry Pi Power Meter V4.0 from Craig Jensen.
Still waiting on current sensors ordered from China.
For more information on Raspberry Pi Power Meter, please visit Craigs' GitHub:
github.com/crjens/PiPower..
and some additional information can be found on this archived Forum thread:
openenergymonitor.org/for..

Here is what is currently available for the project:

Raspberry Pi is powered from APC Back UPS VIA header to pin 2 and 6 providing a common ground while APC is powered from the same phase leg as PiPowerMeter in Single Phase 120/240 house.

Software installation is pretty much straight-forward. Easy to follow instructions in readme file on GitHub:
github.com/crjens/PiPower..
Although, we've encountered issues with VNC being activated on Raspberry Pi.
Also, for whatever reason when Pi was set to boot to Cli (as opposed to boot to logged CLI) sensors did not post any amperage data. So choose boot option to logged CLi.

IMPORTANT!
When installing software run:


not the wget -O - https://raw.githubusercontent.com/crjens/PiPowerMeter/master/setup.sh | bash
as outlined in a readme file. It says:
(you must install with root privileges such as the built-in pi account)
but for some reason missed the "sudo" part and it may not be immediately obvious.
Re-running the installation with "sudo" most likely will not correct the issue and PowerMeter may not function correctly.

After installation and when system is up and running, we found it easier to figure-out correct orientation for the sensors is to set them in "Power Meter Configuration" as Type: Both (out of available: Both, Load, Source).
That way if you see on Load circuit amperage value is Negative - sensor orientation has to be flipped.

Sensors pins numbered in a following fashion:

Hi,

Was wondering how the system was working out for you? I had come across Craig's project (PiPowerMeter) on GitHub and it caught my interest. Was thinking of maybe doing my own build of it. Did you build the boards yourself? I like the flexibility of being able to add additional boards as required.

Joe,
It works just fine. The only drawback is luck of a simple way to save data externally.
All sensors work just fine and it helped me find a couple circuits that were using power when not used and promptly disconnect them.There's no place like ~
