OpenAI Codex Proxy

Local OpenAI-compatible API endpoint backed by your ChatGPT account's Codex OAuth login — packaged as a Home Assistant add-on.

Point any OpenAI-compatible integration (for example an OpenAI conversation integration in Home Assistant) at this add-on and it answers through your ChatGPT Plus/Pro account instead of paid API credits.

Features

OpenAI-compatible endpoints: /v1/responses, /v1/chat/completions, /v1/models, and /v1/images/*
Exposes the Codex models your ChatGPT account can actually use
Streaming responses, tool calls, and reasoning traces
Local API key required on every request — generated automatically on first start (no open proxy on your LAN)
Optional per-request JSON logging for troubleshooting
OAuth tokens refresh automatically and persist in /share/auth.json

Requirements

A ChatGPT account (Plus or Pro recommended for Codex access)
A Codex auth.json file, generated on a desktop machine with npx @openai/codex login and copied to this Home Assistant machine's /share folder

Installation

Add this repository to Home Assistant (Settings → Add-ons → Add-on Store → ⋮ → Repositories): https://git.i3omb.com/gronod/ha-gronod-addons
Copy your auth.json to /share/auth.json (Samba or SSH add-on)
Install OpenAI Codex Proxy and start it
Copy the generated local API key from the add-on log and configure your OpenAI-compatible integration with base URL http://<home-assistant-host>:10531/v1

See DOCS.md for the step-by-step guide, option reference, and troubleshooting.

Credits

This add-on wraps openai-oauth by @EvanZhouDev — an unofficial, community-maintained project that exposes ChatGPT Codex OAuth sessions as an OpenAI-compatible API. Login uses OpenAI's @openai/codex CLI.
