Personally I do not own or even do not see either stoker or Guru.
First I have a patent of gravity feed wood pellet burner.
I built stove and boiler based on my burner.
Later I focus on smoker/grill using my burner.
I developed my controller for my burner originally. Certainly I read many helpful posts in different BBQ forums. Later I found it could be used in most stick pit.
I have sold 100+ pieces of WOLF LION and 10 pieces of TIGER.
Earlier versions of LION did meet problem.
But LION V3 and V4 are good to use. You can program, monitor, control your smoking program from your computer or iPhone or iPad.
But a few buyers of LION still meet problem to set it up to Internet.
My conclusion is that if one can set it up, he can set up without my help. Anyway the LION is a standard WIFI equipment. If one can not set up, I can not help.
So I must need local distributors to help buyers to set up LION to Internet.
The cheaper model of WOLF has same function as LION except remote controlled via Internet.
If you have any idea or suggestion, I can add it on next generation.
It is nothing but to add a short program.
Surface and air (SAL) mail takes 2 to 3 weeks from China to American, mail cost of a controller is around US$20. This is the reason why I need distributors to short delivery time to 2 to 3 days.
