1.Upgraded model will be ready in one week. Dual probes, 3 outputs. It is originally designed for wood pellet smoker, but can be used in charcoal/stick burning smoker, sous vide,
2.WOLF has a big enough fan for most smoker. Indeed it is too big, for most smokers you have to limit the maximum output, which can be programmed by users.
PID is very smart to control the speed of fan. Temperature fluctuation is around 2 F
Right now there is no plan to change LED. You may need a LION, then you can monitor and control the controller via your iPhone or computer inside your room
