Hi all, getting geared up for my first smoke. I've got two thermometers with wired probes that I'd like to use, one for the meat and one for the rack. I noticed there is a small vent hole on the top of the smoker on the back and I planned on running the probe/wires through this hole. My question is, where do I put the actual digital unit for the thermometer? They have magnets on the back, but my guess is that the outside of the smoker may get too hot to just stick it to the side? Any suggestions?
