Has anyone ever used an electric timer set to shutdown the smoker about 20 min before its estimated to be done. I was thinking about trying it. I would set it to stop a little early so there is no chance of overcooking. I can always start it up when I return in a few hours. Example set it to stop at 3 pm arrive home at 5:00 check food. I understand about food safety so I would not let it go for more than about 2 hours with beef. I don't think I would try it with Turkey, chicken or fish?
