I'm doing a pork shoulder today. This thing is rocking. It sits outside and was 36 degrees when I started this morning, and the box got up to temp in just a few minutes. I don't know exactly how fast because I was getting the meat ready, but it couldn't have been 15 minutes. With the Auber PID, it's absolutely amazing. When I remove used pucks or mop, the temp gets back up in just a few minutes.
This is the way it should work out of the box, and I hope the new model does work this way. I really enjoy projects like this, and this was a fun one.
One odd bug with the PID. From time to time, it stops working. The display is normal, and the led blinks indicating heat, but the the temp drops. I cycle the power, and it comes right back up, which means the problem I thought was the thermal sensor in my 4 rack, was actually the PID brain farting. I have a Meat\Air thermometer I use that alerts me to the drop, so it's only a minor irritation.
ETA: 55 degrees outside, running steady at 220. I opened it to mop the meat and the temp dropped down to ~125. It was back at 217 in 4 minutes, and back to 220 in 7.
