Whelp.  With CCS dying in the US. We *really* need OpenEVSE to source an NACS cable or connector for existing OpenEVSE units.

Just opening the discussion. :-)

Need an extra guinea pig pig?   I have an OpenEVSE 50A + suitable wiring + a Rivian R1T + a NACS -> J177s adapter + and a cable I need to replace that's probably only should be doing 32A.

@openEVSE Support  send me one man...  tell me what i owe you lol..   

BTW, my buddy that tested the NACS charger said its wireless "open charge port" button on the OpenEVSE worked more reliably than his Tesla charger at home. :)

@OpenEVSE, we found ODU Automotive is selling NACS pins if you are interested. James.Kruzich@odu-automotive.com was able to get us quotes on pins.

My NACS assembled unit arrived about an hour ago. Not sure if I was part of the very first batch, but I should be able to test it tonight, assuming my friend with a Tesla is able to stop by.

I feel like I'm way too excited about a car charger :P

So I had setup a salvage tesla cable before and used the power from the wifi for the 3.3v, I have units with out that wifi voltage converter.  where can I order more of them?  I can't seem to find that small of inline ones anywhere. 

Just to confirm, I did get the units installed (one NACS, one J1772). Both worked for my test at 24A/5.7kW for at least a half hour. Now on to the HA integration and setting charging based on live hourly TOU pricing! :D

another thing I was thinking, with the J3400, aka NACS, the tesla version uses CAN bus to relay info from the car to the supercharger so the network knows who's Credit card to charge (that you have on file with tesla).   CAN traffic isn't encrypted, so all someone would have to do is stand up a few "free" chargers and skim the users info from the car CAN bus traffic or create a handheld simulated EVSE so the tesla gives up that info, then emulate it on a reprogrammable converter cable (small extension) man in the middle, then one could emulate the recorded vin or whatever data is sent via the can bus to the supercharger and basically perform credit card fraud by stealing free supercharging.      Elon jumps into things too quickly without planning for the long term future. I do like the connector, but some things need to be fixed or cleaned up in the standard first.   I wouldn't use the unencrypted can traffic to handle user tracking especially since it effects a users wallet. 

I've been holding off on buying an OpenEVSE for the past few years as I waited for someone to start selling a NACS cable.  As soon as I heard that Tesla had opened the standard for NACS, I figured that might finally be the catalyst for someone to offer the cable.  Now with Ford and GM (and likely more to follow) saying they'll use NACS, the ball is well and truly rolling.  Does anyone know how much longer we might be waiting for a cable?

I've been tempted to buy a salvaged Tesla mobile connector from eBay to use the cable, but they're all so expensive for something that doesn't work, particularly considering their relative cost to purchase brand new.  Plus, I'm a little hesitant to re-use something that may be damaged in a high voltage/amperage application.

Technically, there's no reason a NACS cable can't wire directly up to an OpenEVSE unit.    Tesla converted them over to more standard J1772 / CCS signing a few years ago.

However, the supply of NACS cables is non-existent at the moment.  Nobody is making them (which is a bit concerning with this industry shift).

We really need a supplier to step up.  Obviously if your vehicle has a J1772 / CCS plug, it doesn't make sense to source an OpenEVSE with the NACS connector... however in 2025/2026 this is supposed to shift rapidly.  OpenEVSE should be ready.
