I have started using a pellet smoker and using the HeaterMeter to monitor temps. I do not use the fan output anymore. One small thing pellet smokers suffer through is as you get to the last 1lb of pellets, sometimes the pellets do not funnel into the auger due to the design of the hoppers. I was thinking a little vibration to the hopper box would cause the pellets to move down into the hole. Using something like https://www.amazon.com/exec/obidos/ASIN/B00AKWRWRW/tvwb-20 or a smaller disc one like this https://www.amazon.com/exec/obidos/ASIN/B072L7PPGY/tvwb-20. It could be controlled or hooked up to the fan controller port?
