SmartSolar Temp -1 when SmartShunt is connecten to Victron BT Network

1- SmartSolar100/50, 1- SmartShunt 500A, 1 - SmartBatterySense, 12V system. All units have current firmware.

SmartSolar stops charging, showing a -1 battery temperature when SmartShunt is added to the BT network.

I have done a factory reset on the SmartSolar. I also swapped the SmartSolar 100/50 with a 100/30 with the same results.

Per the "Limitations" section of the VE.Smart Networking manual, you can't have both a Smart BatterySense and a SmartShunt on the same VE.Smart Network - one sending unit only, else the receiver (your MPPT) gets confused because it's being presented with data from two different sources and it doesn't know what to do with it.
Remove the SmartShunt from the network (don't uninstall it, just remove it from the VE.Smart Network), since it's serving no real purpose - the Smart BatterySense is already sending the battery voltage and temperature data to the MPPT.
For more information please read and fully understand the VE.Smart Networking user manual!
