10.1. Functionality issues

10.1.1. Unit is dead

On first connection the blue LED on the SmartShunt should be blinking.
If this is not the case check the fuse in the VBatt+ cable and also check the cable itself and its terminals.
Please note that the blue LED on the SmartShunt can also be off when Bluetooth has been disabled. The SmartShunt appears to
be dead. See the

Cannot connect via Bluetooth [36]

In case the temperature sensor is used:
• The temperature sensor M8 cable lug must be connected to the positive pole of the battery bank (the red wire of the sensor
doubles as the power supply wire).
• Check the fuse in the positive (red) cable.
• Make sure the correct temperature sensor is used. Note that the MultiPlus temperature sensor is not suitable.
• Make sure the temperature sensor has been connected the right way. The red cable should connect the VBatt+ terminal and
the black wire to the Aux terminal.
See the Auxiliary connection for temperature monitoring [6]

10.1.2. Auxiliary port not working

Check the fuse in the Aux cable and also check the cable itself and its terminals.
In case a second battery (starter battery) is monitored:
Make sure the second battery negative is connected to the load side of the battery monitor. See the chapter
for monitoring the voltage of a second battery [5]
In case the temperature sensor is used:
• The temperature sensor M8 cable lug must be connected to the positive pole of the battery bank (the red wire of the sensor
doubles as the power supply wire).
• Check the fuse in the positive (red) cable.
• Make sure the correct temperature sensor is used. The MultiPlus temperature sensor does not work with the battery monitor.
• Make sure the temperature sensor has been connected the right way. The red cable should connect to the VBatt+ terminal and
the black wire to the AuxAux terminal.

10.1.3. Unable to change VictronConnect settings

Settings can only be changed if the battery monitor is running on the most up to date firmware. Update to the latest firmware with
the VictronConnect app.

10.2. Connection issues

10.2.1. Cannot connect via Bluetooth
It is highly unlikely that the Bluetooth interface is faulty. Some pointers to try before seeking support:
• Is the battery monitor powered up? The blue light should be blinking. If not see the
• Is another phone or tablet already connected to the battery monitor? This is indicated by a blue light that stays on. Only one
phone or tablet can be connected to the battery monitor at any given time. Make sure no other devices are connected and try
again.
• Is the VictronConnect app up to date?
• Are you close enough to the battery monitor? In an open space, the maximum distance is about 20 meters.
