While tracking down the links above I found this: http://openenergymonitor.org/emon/

Hi Arnold, thanks for the link. Since it said open source, does it implies no subscription fee?

That's the implication, I haven't looked at it too deeply but it looks looks interesting. I could probably use it to read the existing CTs that I've installed in the future.

I've played with Arduino before, so using one to read the pulse output from the commercial Leviton OEM Mini-Meter is an interesting solution that I hadn't considered before. The pulses are definitely not high frequency since there will only be 96 pulses representing 0.1kWh each during each hour. Some versions can even be configured for as little as 10Wh/pulse so that gives you a lot more resolution.

Does anyone has a power monitor device with data logging that I can borrow for a day? The idea is to see whether a PV system with battery backup (off grid) could do a 120V 12amp 8 hours of continuous charging. I live in the Bay area and can come to pick up and return.

eGauge also looks interesting. Anybody use that one specifically with an EVSE?

All looks good except it doesn't tell me how much is the system and whether there is a charge if I host my own data on my sever. Thanks for the pointer, it is fascinating to learn such system also monitor gas. I don't have gas but it is good for others.
