[RFI] Weather Station on 433.92?

[digital-conjurers at adelphia.net]

Maybe some can enlighten me on this one:

Just set up a LaCrosse/Discovery Store weather Station (Model FX 5000) that 
has a remote temp/humidity sensor that uses a signal on 433.92 Mhz to relay 
info to the base station.

Is there something in part 97 that I'm missing that allows this sort of 
operation of a consumer device inside our ham bands? [According to the 
national "suggested band plan", this falls right into the 
"Auxiliary/Repeater Links" section.]
