I have a Masterbuilt that has optional firmware updates sometimes, nothing mandatory and certainly nothing automatic. It’s a gravity fed charcoal grill that works like a computer controlled forced air rocket stove. Gets up to 700 degs from cold in 10 mins if I want or hold 225 for the rest of time as long as I keep feeding charcoal into the hopper and emptying the ash bin. The computer is adding actual value.

No soggy pellets, no weird feeding issues, the biggest problem I’ve had with it was the hatch sensors all going out over time, but once I jumped the circuit past them it worked fine again to this very day, going on six years now.
