Does the behavior change if the station is powered up with the display disconnected?
It sounds like either the controller has missing or corupt firmware and needs the software reloaded. Do you have an OpenEVSE programmer?
Here is the latest firmware release.
The guide for uploading firmware:
fyi.. I had the same issue from a kit purchased July 18th. Flashing the firmware resolved it.
I used a raspberry pi.. if you have one of those lying around.
I have the pololu loader. and I can't get it to work. I've been trying for a month. Is there an easier way to fix this? Can I send it in?
We can send a replacement controller, and you can send the one you have back, or you can send the one you have to us for reprogramming.
