Are VE.Direct devices from the MultiPlus GX passed through to the Cerbo GX?

If not, does this mean that in practice all VE.Direct devices must be physically connected to the Cerbo GX in order to appear in VRM and in the device overview?

Yes. You should move all Ve direct and other devices from the MP-Gx device to the Cerb, and connect the MP2 by VE-bus to the cerbo. I would disconnect the internal gx device in this instance.
