We haven't actually had these residential smokers with electronic controls around long enough to have field data. We have used the very best electronics that we can find, while keeping it affordable. Our supplier tells us that the controller will work properly down to
-20F, and UL has subjected it to driving rain conditions, which it passed.
I think common sense would dictate that the electronic controls should be protected from precipitation. I would recommend keeping it on the porch, with something covering at least the top of it.
