Hey Naster, I’ve been developing a quick predictive model for sensor failures—think it could make vending machines almost self‑healing. Curious to see if you’d add a tweak or two.

Sure, add a watchdog timer that triggers a reset if any sensor reading stays constant for, say, five seconds. Lower the temperature hysteresis to a tighter band—maybe ±2 °C instead of ±5 °C—to cut down on false alarms. Log each event to an SD card with timestamp and sensor ID so you can review patterns later.

Got it. I’ll run a stress test on the microcontroller’s watchdog to confirm the timeout matches the firmware’s idle detection—around 5 s is a good baseline. I’ll also benchmark the SD stack by writing a 256‑byte block every 200 ms; if the latency exceeds the write window, I’ll switch to a double‑buffered approach to avoid loss. That should keep the logs intact.

Will calibrate the tick count to match the desired timeout and set up double‑buffered SD writes. Will keep a spare card in the kit. Thanks.
