I looking for a connected power meter for my 240v charging circuit. Either network readable or readable through a iOS app.
I haven't seen something like that but you could purchase a device that plugs inline with the J1772 connector that would do what you want. The juicebox company recently had a kickstarter campaign on it, ~$150 I believe with CA residents getting something like a $50 rebate. It simply plugs inline with your J1772 connector and requires no wiring whatsoever and works with any EVSE.ironmanco said:I looking for a connected power meter for my 240v charging circuit.

It may not be on their site, but they have a 220v version of the 110v Modlet; they communicate with your PC via a USB dongle, and you store data in the cloud with a (free) account. I have one of each: a 220v (with a P6-20 plug) for my EVSE and a 110v for my stereo (I monitor audio/video equipment separately--sort of). They even have an app!
I agree that would sure be nice, but I'm not sure the EVSE knows the batteries SOC? Is that something contained in the J1772 protocol? None of the photos I saw in that EMW link showed SOC% on the phone, unless I missed it.ironmanco said:jjeff said:I haven't seen something like that but you could purchase a device that plugs inline with the J1772 connector that would do what you want.

This looks really cool because it has control in it as well. I didn't see it included on the features but the ability to specific a SOC target % and have it cut off charging would be great as well.

So wait.....you need to have the unit near a computer with a USB connection? That seems kind of problematic.

Cool, it really seems to be a little wonder device for those technically inclined. I believe being able to stop charging at even 80% SOC is lacking on Leafs newer than '13 and for Leafs older than '13 you need to use the timer function to stop charging at 80%.ironmanco said:jjeff said:I agree that would sure be nice, but I'm not sure the EVSE knows the batteries SOC?

Just heard back from the emotorwerks folks and you can set the SOC limit to anything and it will charge to that point.

I guess what I was getting at was...... those that care. People that hang around forums probably care and would be interested in such a device but I bet a good percentage of Leaf drivers just get in it and drive, and when it starts getting low they plug in their OEM L1 EVSEironmanco said:jjeff said:Cool, it really seems to be a little wonder device for those technically inclined.

I'm not sure it's for those that are "technically inclined" as all you have to do is plug it in-line and connect your smart phone or browser to it's embedded functionality.
I think if you can manage your Leaf you can manage this.
