My wife surprised me with an igrill2 :yahoo: The instruction say not to attach it to a hot surface. I use a WSM and am curios where other WSM user with an igrill2 put the unit.
When cooking at lower temps (225 or lower) I attach directly to the smoker. My propane grill is right next to the smoker, so if using higher temps I attach it to the grill. I prefer to attach it to the smoker so I can see it from my back door here I can see the display from the kitchen without having to pick up my phone if my hands are dirty.
