MultiPlus II + Cerbo GX: Generator auto-start via MultiPlus relay

Hi everyone,

I have a system with a MultiPlus II and a Cerbo GX connected via VE.Bus.
I would like to use the programmable relay of the MultiPlus II (k1) to control the remote start of a generator, but with the logic managed by the Cerbo GX (based on battery SoC, voltage or load).

Can the Cerbo GX directly configure the MultiPlus relay for this purpose?

Should I assign the relay under Settings → Relay → Generator start/stop in the GX device?

Thanks a lot for your advice and best practices!
