What you'll do
A watcher for your water heater that Claude Code built — an ESP32 reading a drip-pan leak sensor, the hot-outlet and cold-inlet pipe temperatures, and the element circuit's current draw, feeding a small trend analyzer that learns your tank's normal reheat rhythm and warns you weeks early when the element starts scaling or the tank starts to weaken — and screams the instant a single drop hits the pan, while the floor is still dry.
