How my hobbies helped me to save my fridge
summary
A leaking fridge turns into a diagnostic project: continuity and multimeter checks reveal intermittent compressor/thermostat cycling and two competing thermostats, not a sealed leak. A small Raspberry Pi + ESP32 system with a Bluetooth/BLE receiver and data logger collects temperature and run‑state samples, pushed to Prometheus for graphs. The build is flashed and deployed, shows the hysteresis and miswiring, fixes stop the unwanted cycles and cut wasted run time by roughly 10%, with measurable Green IT impact.
