Builder uses Codex and a Raspberry Pi 5 to make his ceiling AC iPhone-controllable
paw_lean · x · 2026-10-12
Developer swhan0329 kicked off a 'Codex Physical Builds' project: a Raspberry Pi 5 receives commands from his iPhone, fires infrared signals at his ceiling fan-coil AC, and uses a camera to check the louvers and status LEDs to verify the command actually worked. He feeds Codex detailed photos of the Pi, AC unit, and remote to work through the hardware and software. A neat hands-on example of coding agents stepping into physical automation — with OpenAI shipping an official Codex physical builds kit.
