That looks great!
FWIW, I have a Pitboss Pellet smoker, which I retrofitted with a SmokeDaddy PID controller (think of it as the BBQ version of a HERMS). I supplement the smoke with an AMZN pellet tube smoker.
I literally dial in my desired temp, and the PID controller keeps the smoker at that temp +- 5F. I absolutely LOVE it.
