Charger boot looping when Wi-Fi module plugged in
I think that might be the problem, Its enabled on the wifi module but when i disable it doesnt seem to take it reenables. It does also look like its detecting a ground issue, in the wifi module that is no issue without module connected.

Can you confirm GFCI Self Test is disabled in the safety Settings of the WiFi?
Any further suggestions ? Throughout all wiring locations the charger operated normally with no wifi module connected. Only boot loops when wifi module is plugged in.
Rearrange both coils to be close to how they are shown in the guide, still no luck.

Self test of what? I can only see a single coil the current measurement coil. The red and blue wires are currently connected to the GFCI coil sense inputs, not the self test outputs.
I can not see the GFCI coil. If there is no GFCI coil... How can you self test GCFI?
Here is the build guide that shows both coils and how they connect.

Here is a PDF connection diagram.

Those wires go to the self test coil, should i get those close to the base plate ?

I can not come up with any failure scenario that would make the controller behave that way, but we can send a replacement and once we figure out what is causing the problem you can send the good parts back.
I have reviewed the picture again. What are the red and blue wires? This should be for a GFCI coil with self test loop. There are only 2 wires connected and its not clear where they go.
New board behaves the same way , controller issue ? Should I send the lastest wifi board back ?
Understood, I bought some ferrules for the high voltage cabling so when I install those I will adjust the low voltage wiring accordingly.

Hi Rob we sent a replacement WiFi module.
The wire routing is still concerning. The low voltage signal wires from the current coils are now tie wrapped to the high voltage wire exiting the relay. The whole point was to create separation between the low and high voltage components/wires. The wires from the coils should be routed alongside the orange pilot wire as close to the metal plate as possible.
Ive cleanup my wiring as shown below. The bootlooping still occurs only when the wifi module is plugged in. New video below shows this.

THank you for the guidance, ill cleanup the wire and give it a shot, however, worth noting the wiring as is does not cause a problem. Its only when the wifi module is plugged in does the bootloop happen.

The low voltage wires for the coils are running right across the top of the relay. When the relay triggers there is a huge amount of noise. I would guess the reboot happens right when the relay is triggered.
Please take a look at the diagram here:
https://github.com/OpenEVSE/OpenEVSE_PLUS/blob/master/OpenEVSE_PLUS_v5.5/Advanced_2024.pdf
And the build guide here:
https://openevse.dozuki.com/Guide/Current+-+v5.5-v5.6+OpenEVSE+Advanced/26
Both coil wires should be rerouted low in the enclosure near the ground plate. We would also suggest Ferrules on Your AC input and EV cable power lines.
any suggestions ?
