AeroTizen

From the project's README ("Setup"):

You need a computer on the same network as the TV.

1. Download the latest CLI release (cli-v...) from Releases. Extract the archive for your computer: Linux x64, Windows x64, or macOS Apple silicon / Intel. It contains aerotizen, including Python and its dependencies.

   Open a terminal in the extracted directory and check that it finds your TV. On macOS or Linux:

   ./aerotizen discover

   In Windows PowerShell:

   .\aerotizen.exe discover

   Run the remaining commands from this directory. The examples below use ./aerotizen; in Windows PowerShell, use .\aerotizen.exe instead.

2. Turn on Developer Mode on the TV. Open Apps, type 12345 on the remote (or with the on-screen number pad), switch Developer mode on, and set Host PC IP to your computer's IP. On some newer firmware 12345 only works from Apps → App Settings (at the bottom of the Apps tab). Check all four numbers of the IP before pressing OK: the first one doesn't always change. Then unplug the TV for a minute. Turning it off with the remote isn't enough for the change to apply. ./aerotizen status should now show developerMode=1.

3. Create the certificates. This opens Samsung's sign-in page in your browser:

   ./aerotizen certs

4. Install the launcher:

   ./aerotizen install launcher

   This downloads the latest stable launcher release, checks its checksum and compatibility, signs it with your TV certificates, and installs it. No source checkout …

From the project's README ("Choose how Home works"):

Both options run on the TV; your computer can be switched off after setup. Neither needs root.

Option	How it works
Watcher (default)	A background service detects a return to Samsung Home and reopens AeroTizen. Some apps cannot be detected (see Limits).
Native Home (opt-in)	The TV routes Home from other apps to AeroTizen, with optional automatic startup. The watcher is disabled.

Native Home is experimental. Other models and firmware can now test if compatibility checks pass: a 32-bit ARM Tizen runtime, developer access, required native functions and complete settings reads. Apply also checks the installed launcher's eligibility and control service. Physical tests cover a 2024 Frame and a contributor's S90C, both on Tizen 9. The S90C passed Home-only, automatic startup, Home from YouTube/Prime and restore with the app installed. Passing preflight does not prove behaviour on another TV. See the S90C report.

Use matching updated builds of the CLI and signed launcher. Save the original Home backup before opening AeroTizen (replace TVIP with your TV's address):

./aerotizen --tv TVIP home status ./aerotizen --tv TVIP home backup

Then open AeroTizen on the TV to start its control service, and apply Home only:

./aerotizen --tv TVIP home apply --yes

If you already have a valid original backup, keep it. Some TVs change bootingappidbackup to DclHome001.Home when AeroTizen opens. Apply permits …
