i suppose it's property 194, while 194;110;42 seems good, but 194;130;261993922606 ? i have no idea

The attribute log contains the 48-bit raw value as returned by the drive. Raw values are vendor specific and may encode more than one value:
261993922606 = 0x003d000e002e = (Max:61, Min:14, Current:46).
See ticket #1164 for another example.

To track temperature with smartd, try -W directive. See smartd.conf man page for details.
