I have an efergy unit, which connects to a PC, and takes three sensors for
3-phase.
It works OK, sort of.

Caveats with that unit from catchoftheday:
Doesn't connect to a PC, can't log or make readings available on the net.
May only take one sensor input, so probably only works on one phase.
(Doesn't say.)

Caveats with the unit I have (with 3 sensors):
Connects to a PC via USB, but program is Windows only, protocol is unknown,
can only put history onto the PC, not current values.
Doesn't measure voltage or phase, so readings are somewhat approximate.
Can't do 3 phases and J-tariff, its either/or.

Caveats with all those gadgets:
Can give you a shock when you see how much juice you are using.

I'd look elsewhere if you want accuracy or net-connectedness.

Ken.
