I purchased this smoker in 2016, and now, in 2020, the small controller unit that chooses cook temp and duration has died. This library currently provides simple setpoint control over the smoker using a PID control algorithm. The board used was an Arduino nano, because it was the only 5V micro I had available on that critical day when the ribs were seasoned and the smoker wouldn't turn on.
- Give it its own wifi (ESP32? but then need 5v logic and ADC)
- Simple webpage for control/status
- Add a duration to the parameters so that it shuts off automatically
- Upgrade the PID parameters to eliminate the need for a bias - I think it's overdamped
I couldn't find any info online, so I did my own investigation:
- Black - Ground
- Blue - +5V
- Red - Active-high (5V?) element control
- White - Analog thermocouple line
Instead of repeating the formula, look here.
The derivation so far only has a handful of datapoints, and if I had to guess, would say that the effective cooking temp is actually below this reading (my calibration was done with a meat thermometer stuck in the smoke exhaust.
