WIth my long cooks of 16 hours or so, being able to eyeball temps remotely (like when I'm having a tasty beverage down at my local taproom,) from my HeaterMeter is awfully nice. Although, truthfully, I rely on configured thresholds to tell me when something needs to be done, like more charcoal, wrap brisket, or <DING!> Food's done!Believe it or not there are a lot of people who want to monitor their grill/smoker from their iPhone.
My monster gravity fed smoker has completely and utterly spoiled me in regards to the smokes. I can work on improving my food, making other dishes, knowing that I don't have to keep half an eye on the smoker.
