I found some years ago that when reading printer profile patches with my 
i1Pro the readings slowly went up as the i1Pro warmed up. If I read the same 
white patch again and again, the readings slowly increased up to about 100 
readings and then levelled off. If I slowed down the rate of reading to one 
every four seconds, that minimised the increase, so I settled on making 20 
readings of the same white patch to warm the device up and then immediately 
taking the real readings at the rate of one every four seconds. I also took 
20 readings of the white patch at the end to compare with the initial 20 
readings.

So yes, temperature increases affect the i1Pro both for monitor profiling as 
pointed out by Roger and others, and for patch reading. I haven't tested to 
see what happens to temperature when reading patches in scanningmode.
