An AC remote that checks what happened

A Pi sends infrared AC commands and uses a camera to check flap position.

What the hardware does

A Raspberry Pi sends infrared air-conditioner commands, then a webcam checks the position of the unit's flap rather than assuming a command succeeded.

How the agent helped

The creator describes using Codex for component selection, implementation and debugging, sharing photos of the physical setup during development. The observed feedback is flap position, not a measurement of cooling performance.

Before you build

Camera observations show flap position, not cooling performance. Requires wiring, remote-signal capture and model service; unclear results must stay unclear.

A flap photo verifies observed flap state, not cooling performance. Low-confidence results must remain unclear; do not automatically retry IR commands based on uncertain observations.
