These guys basicly have it all figured out but pricy solution, http://www.fumis.si/index.php?page=10&lang=2
I would like to put together something like this but with greater flexibility to add on more control, basics that come to mind are
Thermostat temp and time control.
3 Fan speed controllers
2 Auger speed controllers
I am not at all a programmer but I do see need for certain technology being brought together to make things work better.
Would really like to work with someone on this.
