For Sale: OpenEVSE kit, 25’ cable, newest version

Hello,

I have a 2 month old OpenEVSE charger with a 25 foot J1772 charging cable and a NEMA 14-50R plug.


It’s running the latest firmware (8.2.0) and ESP32 (4.1.3).


I am getting a “No Earth Ground” error when it attempts to start charging. I’m not smart enough to correct this but apparently has to do with the coil. Otherwise works great. Sold as is.

Hi, I think I have the same problem.  The relay isn't holding closed, and when the contacts break there connection, it appears as a lost ground.  I'm starting a thread for this problem.  Mine is less than 24 hours old.

The price please?

I saw this issue show up on my unit when I applied the 8.2.0 firmware. When I rolled it back to 7.1.3 it went away. You may want to give that a try before you give up on it.
