OpenEVSE board for juicebox
No, I still have the original JuiceBox LED lights. They used to be a different color each, now all of them have the same color and lighted regardless of the box status. Is that how it should work for the retrofit? I thought the LEDs should stay the same or at least be dependent on the box status. I can say they are slightly changing color, like when the box is off and unconnected to the car, all 3 are a greenish blue color, when the car is charging, all 3 are slightly bluer, but all 3 are always the same color regardless. I have not seen yellow, red, purple or orange since I changed the board, only greenish blue and bluish blue...

@Danny Did you replace your LEDs with our LED module? If so the new LED module is color changing like in the Juicebox v2. All three LEDs will change color depending on state.
Green - Ready
Yellow - Connected
Blue - Charging
Red - Error
Purple - Sleeping
We are looking into programming individual LEDs to match the old Juicebox, but some of it provides zero value such as the power LED, If any or all LEDs are on then it should be obvious that here is power. Having the all colors of the Power LEDs match the State significantly improves visibility.
@openEVSE Support I have a v1 that needs an LED strip. When you say a picture of the lid, do you mean inside? Or are the outside graphics enough? 
I have this one:

@Danny Sporea The No ground error is a false positive each time the station loses power. We are working on a firmware fix to not register an error until the state is present for more than 1 seccond. We are tracking the issue here: https://github.com/lincomatic/open_evse/issues/176
We have 2 solutions for the LED issue depending on your hardware vairint. Can you send a picture of your lid?
Just a follow up... I was able to get my V1 upgrade board to connect to our WiFi network. We have an extender that had gotten into a weird state so rebooting that got the OpenEVSE board connected. The support note I got suggested updating the WiFi to the Dev release which I did but that did not solve the Earth Ground Check Failed error so it looks like we're going to do a board swap. He also said that there is an LED fix board to sort that out and I'll be getting one of those also. Finally, he said that there were multiple variants of the V1 JuiceBox and that's what they are dealing with.
@OpenEVSE Support I opened ticket #88949 for over a month now and have not heard back. I have the same issues with the LEDs not working correctly and 6 no ground faults. Thank you

@Disapointed Joe
Most users are working just fine. Unfortunately, there is a LOT of variation across the v1 Juicebox fleet. We changed the LEDs to match the most common configuration.
OpenEVSE falls back to hosting its own access point if joining your WiFi fails, this happens if the password is incorrect or the signal strength is too low.
If you have a hardware issue call us or submit a ticket and we will send a replacement.
Basically the same experience with the network. Next time I boot the unit, I'll take pictures of the status screens and put them here so everyone can see them. It sounds like OpenEVSE knows what the various problems are and, being a small company, are figuring out how to sort things out, especially if this may involve software, hardware & manufacturing issues. I posted a support ticket this weekend. I suspect everyone who received these boards are having these problems.
I have to do an inspection of my board (would recommend you also do so by carefully removing the board) to check the solder connections since one person said that there was a solder flow problem that he fixed by reheating the solder. That's not something most people should try since you can cause unintended consequences like shorts.
I am encouraged by the fact that some of the posters are serious electronics engineers (pro or hobbyist) who have access to oscilloscopes and logic analyzers. The goof-up on the LEDs is a black spot. That was highlighted in a review by Transport Evolved News and it was on the basis of her assertion that the bugs in the proto units would be fixed in the production units that I submitted my orders (yes, I've got V1 & V2 upgrade boards in my possession - unfortunately I have a V0 JuiceBox as well - might as well get burned on all 10 fingers).
And I don't know what your experience was, but the original assemblers way overtorqued the case screws and they had molecularly bonded to the case (joke). The hex or torx screws just stripped so I had to drill the screws out (please don't say just use a propane torch - heat & electronics don't mix). So hate to contradict the support note but this is not a 5-10 minute job.
Finally the installation instructions with photos were quite unclear. I may do my own video on how to do this correctly for the units I have since the instructions provided were ambiguous at best and the labels on the board are all over the place because the board is used for multiple applications. Again this upgrade is not appropriate for folks without some familiarity with electronics.
Sorry this has turned into a bit of a rant but did expect more.

Hi Joe,
Where can you see that you unit is in "Host Mode". Mine was doing something similar. I could "connect" to my wifi network but it showed the network strength as 0dbm and also had a red X next to "Connected".
Also similar to you I could not connect to the unit through my wifi after configuring it. Even after restarting I could only connect directly to the unit via 192.168.4.1.
I submitted a ticket about the charging, ground, and wif issues last Wed, still no response.
I'm also having trouble configuring the network. My unit keeps coming up in "host mode" instead of joining my WiFi network. The WiFi network name is there it just (for whatever reason) doesn't want to join. Just get a "connecting" message and then on the next restart back in host mode. Maybe because of the error code it thinks it should stay in host mode.
I am also seeing the Earth Ground Check Failed. First inspected all of the connectors and made sure all of them are in the right place. And got the same error. Then tried charging and get a blue light on my car for a second and then nothing. And the LEDs also do not work.
I'm adding a picture of my JuiceBox Pro unit because there does seem to be some variation. Sunday I'm going to inspect the board for solder issues as was pointed out by another poster.
@openEVSE Support
Yes the station changes from Ready to Connected. I can hear the relays in the car and Juicebox click on and then immediately back off again.

@MRB In most cased Failed Ground Check is just a false positive when the station loses power. There is no need to disable Ground Check. Does the station change state from Ready to Connected when the vehicle is plugged in?
Just purchased and installed the new main board in my JuiceBox Pro40 (v1).
Unfortunately I am also seeing the Earth Ground Check Failed. I did disabling the ground check which showed everything green but I can't get either one of my cars to charge. I can't tell if the cars are rejecting the charger or if there is an issue with the board. No alerts, warnings, or logs on the charger that I can see.
My ID4 displays "charge cancelled"
Anyone else have this problem?

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.
