A lot cheaper and only takes one slot in your panel.

TEG: 3-phase? Where do you live

I posted something I saw on eBay. I just noticed it because it mentioned Tesla in the subject.
I don't have 3-phase at my house.

It measures amps but it looks like you have to cut/disconnect the cables.

You can get to the lines from inside your EVSE box.

 

[dpeilow]

They look like hall effect clamps. No cutting required.

I gave vfx the benefit of the doubt and thought he meant cutting of the cables to get to the individual lines, not cutting the lines themselves to attach the probes.. Either way, no cutting required.

Assuming you could get inside (someone else's box) to isolate a single cable. This

Looks pretty solid to me.

Not all the same features though. The one in the original post says (among other things):

•• FREE PC, Linux and Mac software to read the meter kWh data remotely!!
•• Each meter has it's own network address!

... no cutting required.

Sure doesn't look like a clamp. Seems like you need to get an open end on the wire one way or another to put it through.

 

[doug]

Poor design then. You can get probes that snap around the wires.

My cheap meter has a pulse output that can be used for remote monitoring. Not as snazzy as a network connection but can be plumbed into such.

From what I can tell, the EKM meter was primarily designed for apartment owners that pay a bulk fee for power, and want to bill individual occupants for their actual use.
Thus the need to have multiple units and software to track them separately in a spreadsheet.
I guess it occurred to them that they might be able to sell a few more units if they started advertising them to people wanting to track EV charging too.
