After many hours putting an OpenEVSE together, then weeks waiting for a NEMA 14-50 to be installed, and a few conversations with OpenEVSE about missing parts. I naively plug the charger into my plug. There's a nice click, the screen lights up (with no text) and nothing happens with my Volt. The only thing that does work is the WiFi module which reports lots of 0s.

Save your money and get a prebuilt charger. I'm not sure what to do with this thing. Light it on fire?

Sounds like the code isn't loaded on the control module.

If the relay doesn't activate, then the problem is in the control module.

My JuiceBox EVSE (in my signature since 2014) is from a kit I built. I have never plugged into an EV or charged one, but the relay does close then open during the self test after powering it up. So you may have a software issue. The "click" you heard means that your relay did the same self test.

BTW, you paid plenty for your kit. My kit cost much less and is rated at 80 amps (16kW). The internal power wiring was upgraded to handle that load, but for now I have the EVSE wired on a 40 A circuit, so it was set at 30 A (7.2 kW). And this was in 2014, before GM even announced the Chevy Bolt EV in January 2015 which can accept exactly 7.2 kW (sonehow I previewed the future). I posted the EVSE kit details plus pictures on this forum. Some members commended me because the JuiceBox kit came with a water-tight cylindric case, which I painted as a huge "Duracell Coppertop".

It was a pilot cable issue. JPlug was connected to orange when it should be purple. Volt charges now

 

[Loboc]

Did support help with that, or, did you figure it out yourself?

Ah! The pilot cable plugged itself into the wrong wire. The little devil.

I converted a dead Voltec L2 EVSE into an OpenEVSE. No issues.

Same here. And I built two others from scratch, all worked first try.

But yes, it's easier to just go buy a pre-built one. I, on the other hand, enjoy the experience of building things myself, and saving a few bucks doing so.

Support helped with that. I'll have to comment on the guide so others don't make the same mistake as me. The guide mentions the purple cable is for Tesla and orange for Leviton. It doesn't mention which to plug in only where the pilot is on the board.

I could have easily made the same mistake building my first OpenEVSE. I didn't have the benefit of a guide though so I had to study the J1772 charging standard to track back which wire goes where. It's more fun for me to build stuff myself than just plop down money and get stuff. It also gives me an outlet for ADHD restlessness.

OpenEVSE is a great product. The owner Chris is a very stand up guy. He was going to start selling complete (built) OpenEVSE chargers.
