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.
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.

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. :-)
