Can a Nanocom or Hawkeye read the output from the Internal temp sensoe

I'm thinking of buying one or other of these. I have a suspicion my internal temperature sensor may not be working. Can either of these devices read the current output of this sensor? It might just affect my decision as to which I buy (I'm tempted by the Nanocom).
Cheers!

do you hear it's fan working? ...cos if not the sensor will have erratic readings...a fault of that sensor(open or short circuit) would trigger a fault code in the aircon ECU and set default 25*C, run a manual self diagnostic procedure(attachment)... as the aircon has it's own diagnostic it's not covered by testers

Nanocom is best on the P38, I would expect the same on the Disco.
