Run Codex tasks on your Home Assistant config
Community report: A Home Assistant add-on runs Codex CLI with read/write access to /config, and a custom integration (installable through HACS) exposes actions and entities. Tasks start from scripts, automations, or Assist and run non-interactively. The builder shows an Assist request that had Codex update a dashboard card, followed by a completion notification.

Why it matters
This is the classic promise of AI agents: a helper that handles errands and reminders on your behalf. Real cases like this show how close that promise is today. It is one of 50 sightings filed under Personal Assistant on Agent Sightings (number 36 by interest), and one of 32 involving Codex.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Codex or any similar agent and adjust the details to your situation.
Assistant mode: run Codex tasks on your Home Assistant config. Log every action, prefer reversible steps, and ask before emailing, paying, or deleting.
Tip: Start small: run it once on a low-stakes example, read what the agent did, and only then let it run on real work.
