VE.Bus System Battery Temperature Reading

Both nodes "VE.Bus System" and "System" have a "Battery Temperature" measurement. Both measurements always return "null". There is a MultiPlus II connected to the system with a battery temperature sensor connected.

Any suggestions?

Thank you in advance

@DirkJ

Do you have a temperature sensor connected to the temperature input on the inverter?

Does the temp sensor report its reading to the GX? Check under MP in device list.

Sorry, but I can't find any temperature field in the MP device on GX.

In "Alarm Status" "Temperatur Sensor" shows "Ok".

It's internal temp sensor cannot be read. But the battery temp sensor can be. It reports to the VRM and if working/connected correctly you can see it in under the Multiplus in the devices menu.
