Hello, looking for help to determine if the VE Direct port on my Smart Shunt is working.
The system is composed of a BYD battery with built-in battery monitor connected to a Cerbo GX BMS-CAN port and a Smart Solar 100/20 MPPT connected to the Cerbo GX VE Direct port.
Both the internal battery monitor and the MPPT report data to the Cerbo GX and everything is visible in VRM.
I wasn't happy with the accuracy of the internal battery monitor so I purchased a Smart Shunt and connected it to the Cerbo GX with a VE Direct cable.
The problem is that the Smart Shunt does not show up in the device list on the Cerbo GX. The Smart Shunt is operating and I can access it via bluetooth.
I swapped the VE Direct cables between the MPPT and the Smart Shunt and swapped VE Direct ports on the Cerbo GX. The MPPT will communicate with the Cerbo GX on any of the 3 VE Direct ports and with either VE Direct Cable but the Smart Shunt will not communicate with the Cerbo GX.
I'm thinking that the Smart Shunt VE Direct port is not operating but the unit is brand new and just out of the box so I thought that would be unlikely.
Could this have something to do with the Cerbo GX already having a battery monitor device configured and using the BMS-CAN port?
Thanks
