The Phantom Load Hunter — See Every Appliance in Your Power Bill

You'll walk away with: A whole-home energy monitor that Claude Code built — an ESP32 reading several CT clamps (fitted inside your panel by a licensed electrician) through a precision ADC, running synchronized RMS sampling and a lightweight non-intrusive load monitoring (NILM) classifier that fingerprints appliance on/off "edges" by power magnitude and power factor, then publishes per-appliance estimates — each with a confidence score — to MQTT and a Grafana dashboard with stacked per-appliance charts and a monthly cost breakdown.
