OpenEVSE board for juicebox

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 installed mine last night, the instructions were great! Very straight forward. However, my amperage is fluctuating between 6 and 40 during charging. This doesn’t seem normal. The car, Equinox EV, starts charging when it thinks it needs to be done by 0630. Now the car is saying it needs another hour to make it up to 80%. Also, no temperature readings? Could this be the issue? This is a grey and purple Enel X if that helps.

Hello! I ordered and installed the board for the grey and purple Enel X JuiceBox. I noticed my Equinox EV said it would not be ready in time the following morning. I checked the web interface and found the charger to be jumping between 6a and 40a. Odd. Car estimated it would need another hour to be charged to 80%. I also noticed there were no temperature readings. Could one be causing the other? I submitted a ticket but no word back yet. Now here we are a few days later and the car says the cord is connected but the charger is not sending power. The web interface shows the car to be plugged in but no power is being delivered. Weird.
I had a version 2.01 pcb for my Juicebox generation 2. This was set up for three phase operation. I’m trying to use the replacement open evse pcb series 2 version 1.0 but have an ac 230v relay which it doesn’t seem to want to operate. Any ideas please?

I just restarted the unit and get the following, no count on the GFCI error but it is displayed.

Fault will go away, but will no longer detect car or change from starting

Is this compatible with the temperature sensor? If so, where would be the best place to mount the temperature sensor in a v2?

@OpenEVSE Support - your website is expired - any plans on resolving that soon?  I had this bookmarked and was planning on purchasing the Juicebox kit today.

Sorry to say after only 2 charges this board has now stopped working.


Seems to be stuck in "Starting" mode and will not detect the car.


I restarted via power off, waiting 5 min and starting the unit, I got the GFCI Error, then switched to manual mode and the error went away.  However, it will not go past the starting mode. Of note the 2 LEDs, flash red with the GFCI error, then purple then off.


I then tried the DEV firmware update to see if that would fix it, no luck.


Looking for suggestions, could I have a faulty board? 


I have attached my debug export.json file, do you need anything else?


Looking forward to getting this unit back in working order.

Thanks ! This looks like a good idea, my replacement board however has no LED's on it so can not use this method. I plan on using the LED connector which has 3 LED's green, blue, and orange just need to know if the plug in LED's need to have a resistor added.

Allen Voshall, sorry I was wrong, as I had not turned on the board I did not see the 2 LED's next to the WiFi.  But would still like to add the extra LED's :)

@Troy A couple Lightpipe to the onboard LEDs would be easiest. Another simple way to add more LEDs is add this RGB pixel expansion Module. The pixels are spaced at about 15mm which matches the Juicebox hole pattern.

If you wish to add individual LEDs for Power, WiFi, and Charging using the 1mm ribbon cable as in the Juicebox then you will need appropriate resistors for each LED. Power is 5v, Charging is 5v from the microprocessor output and WiFI is 5v TX from the microprocessor. 

I am up and running, thanks :)  Questions... When plugged in the car is not charging but the dashboard shows 1.8amp 400w is charging. second question when it is charging it seems the current is above what is showing on the dashboard, so my guess is I need to update the calibration however can not find the spot to do this.  Again thanks for a great product.

@troy You can add this sensor here: https://store.openevse.com/collections/all-products/products/temperature-sensor


Temp 1 is an older Real Time Clock Chip that is no longer supported.


Temp 2 is MCP9808 sensor connected to the Controller. When installed it is used for enclosure temperature throttling and Emergency Cutoff.


Temp 3 is an IR sensor that is no longer supported.


Temp 4 is MCP9808 sensor connected to WiFi, It is for situational awareness and logging. 


For your current issue you can update the firmware to the development version. the Settings => EVSE has Current Calibration in there. The default value is 220, you can change this to get it dialed in.



Still have not worked out the "current" issue, so for now, it is way off, I have a question about the temp sendors, all my ones show zero on the web page, do I have to add them?

@Niles This issue has been resolved. We did renew it on April 2nd but for some reason our ISP closed it yesterday and gave us a $20 credit.
