I have three smart shunts in the system. One each engine battery and the generator battery. All are connected with ve direct to usb cables and connected to Cerbo via a usb 5 port to a single usb connection on the Cerbo. I can see all three via Bluetooth but only two show up on VRM or on the Cerbo display. Suggestions? ---

First check if they all appear in the Cerbo, and VRM device list. If not, there is a connection issue in your cables. Victron cables or home built? ---

They don’t appear in either. Just on Bluetooth. Ve to usb is Victron cable. USB extender is commercial. I’ll have to start swapping out and see.
