[Cerbo] Control Generator start/stop using VE.Can

We’re looking to start/stop the generator (relay 1 on Cerbo) using VE.Can but the vreg command to switch the relay doesn’t seem to work on the Cerbo (negative ack) (0x034F + 0x2, 0x034E + 0x1/0x0).

Has anyone done this before using the Cerbo, or is it just the inverter/BMV relays that’s possible to control using 0x034E?

No, I understand you can only do this with MQTT. This is also what I am attempting now, nut I can’t find the proper Topic. If this can be found it should be very easy.
