The Thermocouple is in the middle of the back wall centered in the smoker (the black dot centered between the racks. It’s a waterproof DS18B20. You can see, the smoker is well used.
It maintains really good temperature. I just converted to Lovelace so I don’t have any temp data yet.
This is the controller in Lovelace. Still pretty chilly here in WI.
Sonoff Controller installed into a waterproof enclosure.

Thanks buddy.
That looks sweet!
You previously said only a quarter of the sensor was in the smoker, but from the rear it looks like it is entirely inserted?
I imagine the wire would melt if it was fully inserted?
Any ideas on how I can get the DS18B20 sensor closer to the middle of the smoker?
My Ugly Drum Smoker suffers from wild temperature fluctuations between the middle and at the wall 
A type K thermocouple would solve the issue as it (and the wire) can withstand high temperatures. Would love to learn how to install one to a Sonoff TH.
Alternatively I’m thinking of running a copper pipe across the middle of my smoker, the DS18B20 would insert straight into the copper pipe.
The copper would allow the sensor to pick up a more accurate reading.
Thoughts?
