What you'll do

A battery-backed watcher on your sump pump that Claude Code built — it reads a high-water float, senses whether the pump is actually drawing current, and knows when the house has lost power and is running on backup — and the instant any of those goes wrong it pushes an alert to your phone, then keeps watching even through the outage that killed the pump, because a monitor that dies when the power dies is no monitor at all.
