I turned my Macropad into a Codex status display
I often leave Codex running in the background and wanted a quick way to see whether it was still working or waiting for me without constantly switching back to the app. So I built a small local companion for my Ergohaven Macropad.
The display shows the current phase — ANALYZE, RESEARCH, REVIEW, EDIT, VERIFY, or RUN — along with the elapsed time and number of active tasks.
The RGB lighting reflects the current state:
- blue while Codex is working;
- amber when it needs my approval or input;
- green when the task is finished.
It runs locally on macOS using Codex hooks and Raw HID. No changes to the macropad firmware or Entropy are required, and the previous RGB profile is restored after the last task finishes.
The tool does not store or transmit prompts, responses, transcripts, commands, tool data, or full workspace paths. If an event is ambiguous, it shows APPROVAL rather than risk missing a real request for input.
So far, it has only been tested with my Macropad.

What else would you find useful to see on the display or through the RGB lighting?
