Hi,

I see the problem, but right now it's not possible to talk to the API.

The best thing you can try is to understand on the main-board witch sensor is faulty. I think the sensors for the leakage are the black rings catching what are going through all the 230V cables. Th IC on the mainboard in charge of the whole electric control is the HiTrend Tech ATT7022EU-N (at least on the one I have lying on my desk). Maybe this one is faulty and should be changed.

I didn't think it's a software issue, I think the MCU get a wrong information. But I can be wrong.

At the moment, it's not possible to dump the firmware of the Chinese clone of the STM32, the firmware is protected against reading. This mean you can't reflash it with a fresh one from another charger.

I keep this issue opened as I don't know if there is a better way for chatting publicly over GitHub ... (feel free to advice me the good way if it exist).

Good luck !
