With a kamado, always fill the firebox up with lots of fuel and get the whole thing hot before use. This is the key to a long, controlled burn.
Control system integration is much more useful if you have a cheap steel drum with crappy sealing and a sub optimally designed firebox. You cheap out on the grill and compensate for it with active control systems.
Kind of like a trebuchet vs a sniper rifle. Upgrade your throwing rocks with ESP32 terminal guidance and you’ll be able to knock a guy off his horse just as good as the latter. Or something.
