That is the big benefit. If you are gone, you can still monitor and adjust the temperature of the pit. I have been away from home, checked the temperature of the meat, decided it was getting done too fast, so I dropped the temperature setting for the pit by 25 degrees. All via my iPhone. It is like being there without having to be there. With some software, you can even program it to automatically lower the pit temperature when the meat hits a predefined setting.
