I am considering buying the new juicebox retrofit board to get myself started in the OpenEVSE world. I have exactly zero experience with OpenEVSE, and some experience with DIY electronics (ESP-home).

Could someone help me figure out, before I jump in:

* Is that board all-inclusive, or is any additional hardware required?

* Is it compatible with a screen, or at least a button?

* Is it pre-flashed, or do I need to get a programmer too? Which one?

Thanks in advance.

I get a new "No Ground" error every time I shut off the breaker to my JB V1 with OpenEVSE rescue board installed.  I was advised this is not an issue, and there may be a firmware revision released in the future to optimize the timing of the no ground error.

Thank you

Can you confirm on the new OpenEVSE board (photo below) that GFCI coil is J1 (circled in red), and GFCI Test Coil is J2 (circled in blue)?

I'm also seeing an error of "Earth ground check failed".  I've inspected the board and everything seems to be in order.  LED2 on the board is lit green and LED1 is not lit at all.  My Juice Box is v1 (see attached image), and my openEVSE board is hardware version 1.0.3.

How can this error be fixed?  Do I need a replacement board?  Is it safe to charge my car in the meantime?  Thanks.

Hi and Thanks

Can you confirm on the OpenEVSE board:

GFI coil goes to J1 (circeled in red)

GFI Test Coil goes to J2 (circled in blue)

Thanks!

Hi, can someone point me in the right direction for soldering screw connectors on the V1 board for use on Juicebox V1 with metal case? The new OpenEVSE board is labelled somewhat differently than OEM board. For example, OpenEVSE board does not have J7 or J9 labels, but OEM board does. Also not clear how to preserve polarity. Want to know what connects where and with what polarity. Thanks.

As Chris Perelstein stated, can you state the connectors specs used, and we can crimp on terminals and use that?  Thanks

"Any shot you could also provide the specs on the connectors used on the v1? I have a v0 that I'd be down for crimping some terminals on to in lieu of soldering screw terminals if I knew what to order."

Thanks, that's exactly what I was expecting.

* Is it compatible with a screen, or at least a button?

OpenEVSE moved away from physical buttons about 5 years ago, none of our products are compatible with a button without compiling custom firmware. The retrofit board is compatible with all OpenEVSE parts including displays and temperature sensors. If you want to add the LCD display with WiFi you will need to reconfigure the included wiring harness and disable the on-board WiFi. We can do this for you if you order all the parts from us.

 I have a v2 board in my JuiceBox and Color LCD kit.  How do I make the needed changes to the wiring harness and disable the onboard WiFi myself?

@Ben Ford Regarding the screw terminals, I think OpenEVSE has offered to solder on the screw terminals before shipping if you make a special request.  Also, there has been some discussion of the LEDs and options on the OpenEVSE Discord channel:  https://discord.gg/Y3ftbUd4rR

I will throw out there that I have a v0 and possess very mediocre soldering skills. Was hoping to crimp some connectors instead. Honestly I'd just go for the soldering. It's literally the easiest soldering job I've ever done to put the screw terminals on. Only "tricky" part is I had to reroute wires due to different enough locations and had to replace the coil test wire as it couldn't quite reach. Again this was super easy as I already had comparable wire lying around.
