Alexa, Google, HomeKit
All three assistants control lighting, climate, scenes and shutters on the same installation, without choosing an ecosystem up front.

Voice assistants and AI
Three voice assistants on the same KNX installation, and an artificial-intelligence layer that is part of the system rather than an external service it is handed over to.
How it connects
Natural language
Requests in everyday language are translated into commands for KNX objects and third-party devices — no syntax to learn.
Questions, not just commands
Status, history and activity logs can be queried by voice, without opening a chart or navigating a menu.
ChatGPT via API
The server integrates ChatGPT through the OpenAI API: requests, questions and analyses run on OpenAI’s models.
MCP server
The server speaks the Model Context Protocol. Any MCP-compatible AI — an assistant, an agent, a tool of your own — can read states and send commands to the installation.
Local AI too
MCP also works on the local network: paired with a model running on site, commands and data never leave the building.

Frequently asked
Do I have to pick one ecosystem?
No. Alexa, Google Assistant and HomeKit all work against the same installation, which matters when a household or a hospitality project has users on different phones.
Does the AI answer in the user's own language?
Yes. The model understands and responds in the language of the person speaking — the reason it holds up in hospitality and international projects.
What does the AI do that a voice assistant does not?
It analyses the system continuously and flags deviations — a load drawing more power than it should, or solar production below threshold — so the installer can act before the customer calls.
What is MCP and why does it matter?
The Model Context Protocol is an open standard for connecting AI models to tools and data. Because the server supports it, the installation is not tied to one assistant: ChatGPT, another MCP-compatible AI or a model running locally can all operate it.
