that is a good looking graph from the Fireboard.
I had a temporary need to log smoker and meat temps for a group event (so timing mattered), and hopefully chart them. I settled on Fibaro FGK-101 (refurbs on Amazon) and DS18B20 temp sensor with high-temp silicone cable ($12 for 2 on Amazon). The sensor is only rated to 257F - just within smoking temps. I meant to heat a sensor to failure but I only have two for testing and I needed smoker and meat temps. The silicone should be shielded from radiant heat to keep it under 400F, which I wrapped with newspaper and tinfoil.
It’s not super cheap but it was convenient to put the smoker on Grovestreams or dashboard with existing device handlers.
here’s my fugly graph for making pulled pork last week:
