Developers
A local API behind a single address, an MCP connector for AI assistants, and an open-source Home Assistant integration. Enough to plug the display into your own code.
What's open
The Home Assistant integration is published under the MIT license: the code can be read, modified and reused freely.
Full setup instructions (with or without HACS) are on the smart home page. Contributions — fixes, newly supported entities, translations — are welcome as pull requests.
The firmware running on the display itself is not public today. Only the Home Assistant integration is.
The local API
Every display answers to a personal web address. Calling it with a
message parameter replaces the text shown; a
slot=evenement parameter sets a short-lived text that clears itself.

No API key to request, no developer sign-up: it's the same key as your account. Full parameter reference, examples for Home Assistant, Jeedom, Node-RED, a script or a scheduled task, and troubleshooting are on the smart home page.
MCP connector, for AI assistants
The display also speaks the Model Context Protocol (MCP), the open protocol used by AI assistants. An MCP connector reads and changes the settings in plain language: "show the weather for Paris", "send HAPPY BIRTHDAY GRANDMA".
Connecting from Claude or any other MCP client — address, settings and example commands — is on the smart home page.
A question, a bug, an idea?
For the Home Assistant integration, an issue or a pull request on GitHub is the fastest way. For everything else, write to us directly.
