Basically you can compare my DOG package with Auber.
Small differences are
1.DOG uses a big AC/DC addapter, in turn a big fan
2.DOG's output is variable voltage, in turn variable speed of fan. This way a big fan can suit small, medium and large smoker. If you have a 50 CFM fan, but you have a Web 18.5" smoker, you can define HDC as 60, then maximium output of a 50 CFM fan is indeed 10 CFM. The speed of fan will run at maximium or run slower depending on PID math result. The fan will deliver 10 CFM then 8 CFM then 1 CFM.
Auber output is solid state relay. If you have a 10 CFM fan, the fan simply delivers 10 CFM constantly, only on or off.
3.DOG has 4 temperature stages. Say you can program smoker temperature at 225F for 10 hours, then lower to 200F for half hours, then 180F for half hours, and finally 140F as keeping temperature for ever
