Own TV with REA: greco’s remote and Mac-mirror demo

greco (@greco_dev, data engineer) published an own-television reverse-engineering note, used REA, and linked github.com/morluto/rea. rea.run credits that post and does not add protocol steps the author did not publish.

5/5 — Own-TV remote demo

Quality. Short public post that links the repo and shows a control-panel demo.

Evidence. Public X post (Portuguese) plus a self-hosted clip. Author wrote that they used REA and linked morluto/rea.

Limits. Feature list is the author claim. No TV brand, no protocol write-up, and not a universal remote tutorial.

For. Builders who want an Evidence workflow on a television they own.

Author demo: a personal control panel for their own TV (self-hosted; from the @greco_dev post).

Short version

The original post is in Portuguese. In it, greco says they reverse engineered their own TV and used REA. The features they list: switch app or input, volume, remote control, mirror a Mac screen, screen time, and general controls such as brightness and contrast. A short demo video is attached. rea.run hosts a copy of that clip and links the post.

Attribution (read this)

Credit: greco, @greco_dev. The post says they used REA (“usei o rea”) and links github.com/morluto/rea. It is still not a rea.run session log, and this page does not invent steps that are absent from the post.

What the author demonstrated

Own device. Their television. The post does not name a brand or model.
Tool credit. They wrote that they used REA and linked the upstream repository.
Features they listed. Switch app/input; volume; remote control; mirror the Mac screen; screen time; general controls (brightness, contrast, and similar).
Demo. The clip above is a self-hosted copy of the attached video: a personal control panel for that set. Full context and any later edits stay on the X post.

How this relates to installing REA

REA is the local MCP/CLI that lets a coding agent inspect software you are allowed to analyze and return Evidence plus unknowns. This post is an own-device story that uses that tool. To mirror the lawful shape — not the unpublished internals — install REA, point it at a target you own, and ask for Evidence.

Install. Paste into your agent, or run it yourself: npx rea-agents@latest setup. Then restart the client. Walkthrough: /docs/install/ · Codex demo: /docs/install-demo/.

Nearby cases. @thinkszyg’s toilet BLE remote and @BrOrlandi’s scale dashboard are other own-device stories on the same wall.

What to copy (authorized hardware only)

[ ] The television (and any app or firmware you inspect) is yours, or you have written permission
[ ] You ask the agent for Evidence and unknowns after setup
[ ] You do not publish keys, pairing secrets, or a method that controls someone else’s set
[ ] You do not treat this page as a DRM-bypass, account-bypass, or firmware-extraction recipe
[ ] Screen-mirror and picture controls stay on equipment you are allowed to operate

Compliance

Lawful RE only: a television, companion app, or firmware copy you own or are authorized to analyze. This card does not teach DRM bypass, account bypass, or access to someone else’s set. The author is not affiliated with rea.run.

Takeaways

Credit @greco_dev: a Portuguese post that says they used REA on their own TV and links the repo.
Listed features: app/input, volume, remote, Mac screen mirror, screen time, brightness and contrast.
Install REA for an Evidence workflow on targets you may analyze. This page is not a bypass guide.
