Personally like this system from Accurite. It is wireless and it does utilize batteries and has it's own display such that you can use the display and Homeseer to monitor both your refrigerator and freezer.
AcuRite 00986A2 Refrigerator/Freezer Wireless Digital Thermometer
Thinking too that RFXCom will read this sensor. Recently here have added (playing still) a Meteostick which does read Accurite wireless sensor weather station stuff.
Over the last few years here have had to replace an ice maker (2 years old) and did spend some time taking this and that apart. There are now low voltage panels and sensors inside of the freezer and refrigerator. You might be able to tap in to one of the boards for some low DC voltages.
This one (which I still have) is a Kenmore Elite. Old now and working fine with the replaced ice maker. Moved to garage - probably going to move it to the basement.

Current newer combo frig and freezer has all LED inside illumination. Guessing these lamps are DC powered. I am already having issues with the piece of crap ice maker in it. (less than one year old and still under warranty any how). It is a Frigidaire gallery side by side job. Junk actually compared to the Kenmore Elite.
