Alex Miller uses Claude and Codex to write local Home Assistant automations

Alex Miller, a solo builder, says Claude and Codex can write the deterministic routines that run a smart home locally, without cloud servers.

He uses Home Assistant with the community "Unofficial and Awesome HA MCP," which lets the agents handle configuration, automations, and debugging.

He describes house modes such as Home, Away, Sleep, and Out of Town, switched by phone location sensors, and lighting that adjusts through the Adaptive Lighting package. He announced a written guide on X on October 28, 2026, but the report contains only his post and does not include the guide's steps.
