Qubev Smart charger - says its OCPP 1.6J compliant but I can't get it to talk

[MHKnowles]

Hi all,

My Rolec wallpoint decided to melt itself last week so I installed my newly bought QUBEV Smart charger today. I managed to get the app working (after a while of working out that the charger doesn't support 5GHz wifi) but there's scant documentation for it and whilst it mentions how to configure the OCPP settings in the app i'm not confident i've configured it correctly (I'm an IT support guy for the last 35 years so i'm not a newb).

Every device sensor reads "unavailable" except Maximum Current which worked out it should be 32Amps but i'm not sure whether that's because the QUBEV app told it or because OCPP is slightly working.

So, two questions:

1. Has anybody else got one of these QUBEV Smart chargers working yet?
2. Where do I interrogate the logs for OCPP in HA?

Thanks,
Mike.
