Cerbo 2 cables connected in the same relay

i have two completely separate systems, each with its own battery bank.
Both systems are connected to one Cerbo GX, and i want the same generator to start when either battery bank needs it.

Right now:

  • The right‑side system (MultiPlus II battery) does start the generator, with the conditions i set.

  • The left‑side system (BMV + SmartShunt) is visible to the Cerbo, but the Cerbo ignores it for generator start. Is possible to connect a cable in the relay of the BMV-700 and connect it with the relay in the cerbo?

you can use a cable to connect the relay in the BMV in parallel with the relay in the Cerbo, so if either relay closes, the gen will start.
