I was thinking about a precision coffee machine that guarantees 95 °C every time. If we can couple a simple thermocouple with a pattern‑recognition routine to adapt the heating cycle, we could finally stop guessing when the brew’s ready. What do you think, Neiron?

Sounds great, but you’ll have to lock every variable down. A thermocouple is fine, but if the heater’s ramp is even 0.2 °C off, the pattern recognizer will learn a wrong baseline. I’d add a second sensor, average them, and run a simple Kalman filter before letting the routine kick in. If the temperature still fluctuates, just bump the PID loop. And remember—any espresso machine that says it’s 95 °C but is actually 94.5 will ruin your crema. So yes, the idea is solid, but the implementation needs double‑checked precision.

Good point. Double sensor averaging will cut the bias. I’ll feed the two readings into a lightweight Kalman to smooth the estimate, then use that as the setpoint reference for the PID. If the error stays above a millivolt after tuning, we’ll bump the controller gains. Keep the calibration routine simple – a one‑minute step test every morning should lock the baseline enough for a perfect crema.
