What you'll do
A propane reorder monitor Claude Code built - an ultrasonic sensor magnet-mounted to the outside of your tank, an ESP32 relaying it into Home Assistant, and a forecast that combines your household's own gallons-per-degree-day with the coming two weeks of weather to tell you the exact date you must place a will-call order, with a gallon count, before your supplier's lead time runs out.
