Here's the temperature graph (°C on the right axis)

Wierd.

That shaded blue - fan speed?
Did the food temp probe hit a bone? Fall out?

Yep - blue shade is fan speed. I also run a servo damper.

Orange is the pit thermocouple, the 2 bluey-green lines are food probes, stuck into adjacent lumps of meat.

I need to work on the PID settings a little to stop the temp dropping so far when I remove the lid / lower the temperature, but that's secondary to the weird goings on.
