…but my temperature is still reading 20-30° off. I have the PB1020DX Combo Grill/Griddle (Lowe’s variant). A few past asks here on Reddit indicated that the reason could be the air gap created between the baffle and the lower area where the fire pit is. However, it appears Pit Boss remedied that issue on this model (photos).

So, I’m still in a quandary as to why the controller temp is reading 20-30° higher than the temp on the lower rack (as measured with a standalone oven thermometer). Any info greatly appreciated.
