The reason I ask is threefold. 

 1. I watched my gravity readings go up from 1.039 to 1.043 as I cooled my wort before I pitched. 
 2. I noticed in the System page of my TiltPI, it says `SG 15C/59F (default)`
 3. When I cold crash, the gravity readings go up. When I enter the temperature and gravity reading in a [hydrometer temperature adjustment calculator][1], the gravity is the same as before the cold crash.

It seems beyond reason that this device would need to be adjusted for temperature, since it is both a hydrometer and thermometer, but that appears to be the case.
