What you'll do

A tiny battery-backed watcher, built from firmware Claude Code wrote, that senses whether your house is running on the grid or on your generator — using only isolated plug-in chargers, never touching a mains wire — and texts your phone — as soon as it can reach the internet — when it switches to backup, when a full blackout hits, and when the grid comes back.
