OpenEVSE board for juicebox
Does the MCP9808 temperature sensor work with JuiceBox V1 replacement board and will it limit current based on temperature?

I upgraded my non-functioning JuiceBox V2 yesterday using both this OpenEVSE tutorial and this Youtube tutorial, which was useful but a bit unnerving as the youtuber got it wrong on the first try and never explains his mistake. In my caution, I labeled each wire as I disconnected it, first finding it in OpenEVSE tutorial using supplied pictures and text, then affixing a label matching the correct position on the OpenEVSE board. There are three same-sized plugs that you could mix up if not careful. My labels made it easy to get it right; the station is working perfectly! This is a great example of "reuse, repair, recycle"! Much of the JuiceBox is retained and reused, including all that copper, plastic case and fittings, beefy handle, etc. All that gets recycled is the old board. Thank you OpenEVSE and Chris Howell! Please consider making a specifications label that can replace the Enel X label, and a big OpenEVSE label to cover the word JuiceBox!
@Ernest DiNino - I have the same problem with a v0 (solid metal case) and after I plug it in, no lights, no click, nothing. I'm going to check whether the 12VDC relay is connected correctly and I believe it's not polarized but will test.
@David Tsao. Thanks. I followed the directions exactly per prior posts on this thread. If you can give any insight that would be great.
I have a very old unit that has no LED's, I have almost completed the cutover and would like to use the LED's I have made a connector but would like to know if the LED's need to have a resistor added, I see that board has 3.3-5v next to the connector. maybe a 150 ohm?
Keep up the great work :)
@Troy Dangerfield I Have an old JB 75 PRO that never had LED's.
The Juice rescue board has LED's on the board, so I drilled the front of my case above the LEDs, and added 2 of these light pipes:

@Ernest DiNino @David Tsao posting pictures of your installs (clear pics of all connections) would probably get useful responses. Also, the Discord server seems to be monitored more regularly: https://youtu.be/0MQJ4ZFYQyw
(We've swapped control boards in 25 Juiceboxes -- v0, v1, v2 -- and they're all working great)
@Ernest DiNino I figured my situation out - even though I labeled each set of wires with a label maker, I somehow swapped the pair of wires for AC Input and AC Test wires. When I correctly wired them, the board turned on. Hope this helps!
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.
@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.

@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.
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.

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.
