Is this a MPPT bug or am I configured wrong?

My Setup:

  • Multiplus 12/3K
  • VE Bus
  • MPPT 100/50
  • Cerbo GX
  • Linx Shunt


Battery Bank is:

  • 3x 206ah LiPo


On Battery #1:

  • Temp Sensor connected to MPPT

On Battery #2

  • Temperature Sensor connected to VE Bus Dongle


MPPT, Cerbo & VE Bus are all part of VE.Smart network.

MPPT , Multiplus & shunt are hard wireed to the Cerbo GX by their various forms of cables.


With the Temperature sensor connected to the MPPT, voltage and Temperature report correctly on the Victron connect app MPPT Display


With the addition of temperature sensor connected to the VE Bus Dongle, the MPPT reports that external battery voltage and temperature will be synced from it.

The Temperature is reported on the connect app display as double the actual temperature while voltage remains correctly reported


So I ask ...

Is this doubling of temperature a bug?

Are multiple temperatures seniors allowed?

If only one Temperature sensor is to be used then what device ( MPPT or VE Bus) and which battery

You have a Cerbo, you really shouldn't be using smart networking. Wire all the devices to the Cerbo and try again.

Also worth reading the limitations section of smart networking:
