Tessera manual

Tessera turns a small touch screen into a control panel for your home. You install one app in Home Assistant, plug the screen in once, and choose its tiles with your mouse. From then on, you change the tiles whenever you like, without touching the screen again.

Inside Home Assistant the app is called Tessera Screen Manager. Its page in the sidebar is Tessera. This manual calls them the app and Tessera.

What you need ​

• Home Assistant OS, on a 64-bit Raspberry Pi (4 or 5) or any 64-bit Intel or AMD PC, such as an Intel NUC or a mini PC. What counts is how Home Assistant is installed, not the hardware: Settings > About shows it under Installation type. Home Assistant Container has no app store: use the Docker route instead.
• A supported screen. Supported screens lists them, with what each one can do.
• A USB cable that carries data. You need it once, for the first install. A charge-only cable looks the same and does nothing.
• 2.4 GHz Wi-Fi. The screens can't join a 5 GHz network.

Where to start ​

• New here? Install the app, then add a screen. Half an hour, most of it waiting for the first build.
• Know Home Assistant well? The quick start is the whole setup on one page.
• Screen on the wall already? Read what the screen does, how pages and tiles work, and what every setting means.
• Something wrong? Troubleshooting goes by symptom.

Use the search at the top for a setting, a tile type or the exact words of an error message.
