GFCI fault why? Logging?


I’m very new to this. Received my openEVSE on Monday. My car won’t be available for another week at least, just preparing things at the moment.

While I was testing an MQTT feed for future solar charging I noticed an error on the openEVSE web frontend: “GFCI fault”. A few seconds later the error disappeared and things appeared normal again.

The openEVSE was bought fully assembled. Fresh out of the box, never got wet, no car connected. How can it possibly get a GFCI fault?

I was logging all MQTT traffic at the time. I can’t seem to find any mention of the error in that log. Should there be something?

Any hints appreciated. Thanks so much!


Hi Peter, welcome to the forum!

Did you buy this unit from the OpenEnergyMonitor Shop:

I ask because we only sell OpenEVSE kits, not fully assembled ones. We do sell fully assembled emonEVSE charging stations: EmonEVSE WiFi Connected EV Charging Station (Type-2) - Shop | OpenEnergyMonitor. They are similar in many ways, but are not the same thing. Could you clarify which one you have?

Hi Gwil,

thanks for the friendly welcome. I hope I’m in the right place here with my question.

I got this one here: OpenEV Store - Advanced Series - 32A Mennekes IEC Type 2 Single Phase Charging Statio

When I tried googling the error I found related posts in the forum here. Didn’t come across anyone having exactly the same issue though.

That’s fine, it’s possible somebody here might know.

If not, OpenEVSE have their own forum here: Discussions : Support.

Thanks for the link. I’ll have a look.

What’s the relationship between the two projects, is there an article somewhere explaining this?

OpenEV and OpenEnergyMonitor are separate projects. We resell the OpenEVSE kit and have developed own our unit, the emonEVSE, based on their design. There’s a bit about that here:

Hi @Peter_WA,

If the unit was purchased via OpenEVSE / OpenEV you should contact them for support, we can only support units purchased via the OpenEnergyMonitor store.

OpenEnergyMonitor is the European reseller for OpenEVSE.
