In today’s homes, convenience begins with a voice.
“Hey Siri, turn off the lights.”
“Alexa, start Movie Mode.”
“Hey Google, lower the blinds.”

Homeowners expect everything to respond instantly, regardless of the device, brand, or app. Yet, for years, professional-grade automation systems like KNX have existed in a world of their own. Built for reliability and scale, KNX was never designed to speak directly with consumer ecosystems like Apple Home, Google Home, or Alexa.

That’s where Cue comes in, bridging the gap between professional automation and everyday simplicity.

The Challenge: KNX Was Never Built for Voice

KNX is unmatched in its reliability, scalability, and engineering precision. But its strength, a dedicated, bus-based architecture — also made it difficult to integrate with fast-evolving voice and cloud ecosystems.
Traditionally, achieving full integration meant stacking multiple devices:

• A KNX IP router

• A control processor

• Cloud connectors for voice platforms

Every added component increased complexity, cost, and maintenance effort. Integrators often faced days of repetitive programming and long commissioning cycles. Users got a reliable system — but not necessarily a smart one that worked with their preferred voice assistant or app.

Cue’s vision was clear: make KNX as simple to integrate as a Wi-Fi smart plug, without losing its professional backbone.

The Cue Breakthrough: KNX, Matter, and Home Assistant in One System

With Cue Core and Cue Desk, that vision became reality.

Cue Core is not just another controller — it’s a purpose-built automation hub with KNX built-in. There’s no need for an external IP router or an additional control system.
Even better, Cue Core also acts as a Matter Controller and Matter Bridge, bringing seamless interoperability with Apple, Google, Alexa, and hundreds of Matter-certified devices.

And powering it all is Home Assistant, the world’s most advanced open-source control engine. Together, they form a stack that’s fast, local, private, and incredibly adaptable.

Now, one device — Cue Core — does what used to take three.

How It Works: A Unified Logic

Here’s what happens under the hood:

• KNX devices communicate via the KNX bus.

• The integrator exports the ETS project file (.csv).

• Cue Desk automatically reads the configuration and maps every address to its corresponding room.

• The KNX entities are exposed to Home Assistant and, through Matter, to Apple Home, Google Home, and Alexa, instantly.

No duplicate programming. No custom scripts. No waiting for cloud syncs. Everything runs locally, ensuring lightning-fast response times and enterprise-grade privacy.

With this integration, KNX becomes the professional heart, and Matter becomes the universal language connecting it to the world.

Why It Matters for Integrators

For professional integrators, this changes everything:

• Simplified architecture: One controller replaces the KNX IP interface and control system.

• Faster deployment: Cue Desk’s auto-ETS sync reduces setup time by up to 70%.

• Future-proof platform: Add Matter or Wi-Fi devices later — no reprogramming required.

• Unified control: KNX devices can be managed via Siri, Google Assistant, or Alexa without losing professional configuration control.

Cue transforms KNX from a specialized technology into a universal platform, empowering integrators to deliver projects faster, smarter, and with fewer support calls.

Why It Matters for Homeowners

For the end user, it’s the experience that matters.
With Cue, KNX lighting, HVAC, and shading systems work effortlessly with consumer devices like smart speakers, voice assistants, and connected appliances.

• One app.

• One unified experience.

• One system that never goes offline.

It’s Apple-grade simplicity built on professional-grade reliability.

Privacy and Reliability, by Design

Cue’s architecture is local-first, meaning automations, device control, and data processing stay within the home.
Internet access is used only for remote control, always via encrypted tunnels. The system runs independently, even when connectivity fails. That’s the Cue promise: reliability that feels invisible.

The Bottom Line: The Future of KNX Is Here

For decades, KNX has been the gold standard of professional automation. Cue amplifies that legacy by making it compatible with the most powerful ecosystems in the world —Apple, Google, and Alexa — all from a single controller.

For integrators, it’s simpler projects, faster setup, and limitless compatibility.
For users, it’s a smarter, more human experience, where every device speaks the same language.
