The full story
When his iAqualink 2.0 became unusable, the poster lost control of his pool. He spent a week working with Claude on ESPHome firmware that lets an inexpensive M5Atom Lite talk to the Jandy AquaLink bus directly.
He says he didn't write the code, Claude Code did, and he checked it against a set of safety and security rules. It is now running his pool, with more work still to do.
