Yessir.
That hopper unit is basically what you would find hanging off the side of a traeger. The pellets are fed from the hopper to the burn pot via an auger, then ignited with what is basically a glow plug (like in a diesel engine), then air is blown into the burn pot with a fan to keep it going.
Temp is monitored by the controller with a probe in the cabinet, and auger feed speed along with fan pulses to keep temp constant. (The smoke mode pulses the fan on and off to get more smoke out of the deal)
