The value was missing in the configuration.
I verified the register on a live system (Vaillant flexoTHERM) by comparing hex dumps with the display values.

  • Reference (SourceTempOutput):

    • Register: 32 27
    • Display value: 7.5 °C
    • Hex value: 0x79 (Decimal 121)
    • Calculation: 121 / 16 = 7.56 °C (Matches)
  • New Sensor (SourceTempInput):

    • Register: 32 22
    • Display value: 7.1 °C
    • Hex value: 0x74 (Decimal 116)
    • Calculation: 116 / 16 = 7.25 °C (Matches within tolerance)

The definition uses the same decoder (D2C) as SourceTempOutput.

I hope i did it right in the tsp file. I wrote this
r,,,SourceTempInput,Soleeingang,,,b51a,05ff3222,value,,IGN:3,,,,value,,D2C,,°C,
to my 08.hmu.csv file and this shows me the right Source Temp Input.
