I'm thinking about buying one of those BBQ thermometers that has a probe and wireless signal to monitor temps coming out my stack - and possibly on the stove itself. I was having breakfast this morning and thought I had built perfect fire, but found that it was smoking like hell and the alarm on a BBQ probe could have told me that the temperature was too low. But also thought it would be interesting to monitor temp coming out the stack with my current non-cat stove and then with my new cat stove that I'm getting next week. A friend has, or jerry rigged, a BBQ thermometer on his green egg so he can monitor temp on his computer or handheld. Anyone have a advice on an affordable thermometer probe that goes up to say, 800 degrees?
