As I'm rapidly finding out, there's quite a lot of equipment out there (alternator controllers, battery management systems, motor controllers suitable for electric/hybrid boats...) which are crying out to be integrated into an electrical system using a central controller/display like the Cerbo GX, but which use CANopen as a protocol not the (closed, pay-to-license) NMEA2000.
At the moment there seems to be no way of connecting these into a Victron-based system, so everything needs its own separate display/control system -- which goes completely against the aim of the Cerbo GX, as well as adding to cost/complexity/panel space.
Does anyone know of a way of doing this, or whether CANopen is likely to be supported directly in the future by the Cerbo GX? There seems no technical reason that this isn't possible, indeed it should be quite simple, and these are products that Victron don't make so there isn't a direct commercial conflict in doing so...
