Is my pylontech battery properly connected to my Cerbo GX?

Hi,

I am using the Cerbo Gx for the first time and I am not sure that my pylontech battery (turboplus) is communicating with my cerbo. How to check it?

When going into the config of the cerbo, in battery monitor, I only have the options of automatic, no monitor or the inverter (please see picture).Screenshot from 2022-04-14 21-53-34.png

The pylontech is connected per ethernet cable from the A/Can port to the left BMS-Can port of the Cerbo and I put the blue terminator plug in the other BMS-Can port.

Thank you for your help

As I mentioned in the other question you need a special cable for that, not just a simple patch cable.

I am using the cable that comes with the cable kit from pylontech (there was the 2 cables for the battery and 2 ethernet cables).

That cable is not correct.

You need a Victron type A cable or at least one with the correct pin out.
