Control KNX devices via Apple Home with Homey

Control KNX devices via Apple Home with Homey

KNX devices don’t connect to Apple Home on their own. KNX is a professional building automation system, designed for stable and long-term installations, not for direct integration with consumer smart home platforms.

To control KNX  devices using Apple Home, you need a smart home hub that can connect to KNX and make those devices available to Apple’s platform.

Homey acts as that bridge, exposing KNX devices to Apple Home.

Homey stays in control of the KNX system. Apple Home becomes an additional way to control devices using the Apple Home app and Siri.

What you need

To control KNX devices via Apple Home, you need:

KNX devices are configured in Homey using their group addresses.

What “exposing devices” means for KNX

When Homey exposes a KNX device to Apple Home, it means Homey represents that KNX function as a smart home accessory Apple Home understands.

The device:

  • remains part of the KNX installation
  • continues to be controlled by KNX logic and Homey
  • becomes visible in Apple Home

Apple Home does not communicate with KNX directly. All commands go through Homey.

A simple way to think about it is that Homey translates KNX functions into Apple Home accessories.

How to expose KNX devices to Apple Home with Homey

Exposing KNX devices is done from within Homey. You don’t need to modify the KNX installation itself.

The process works like this:

  1. Connect Homey to KNX
    Add your KNX IP interface in Homey and configure the required group addresses.
  2. Add KNX devices to Homey
    Define lights, switches, dimmers, blinds, or other functions using their KNX group addresses.
  3. Connect Homey to Apple Home
    Enable the Apple Home integration in the Homey app and sign in with your Apple ID.
  4. Select which KNX devices to expose
    In Homey, choose which devices should be exposed to Google Home.

After this, the KNX devices appear in the Apple Home app automatically.

How the connection works

Behind the scenes, the setup works like this:

  1. Apple Home sends a command
    This can be a tap in the Apple Home app or a Siri voice command.
  2. Homey receives the command
    Homey interprets it as a KNX action.
  3. Homey sends the KNX command
    The command is sent to the KNX bus via the IP interface.

What you can do in Apple Home

Once exposed, KNX devices appear in Apple Home as standard accessories, such as:

  • Lights and dimmers
  • Switches
  • Blinds or shutters

You can:

  • Control devices in the Apple Home app
  • Use Siri voice commands
  • Assign devices to rooms
  • Include them in scenes and basic automations

What to keep in mind

A few important points:

  • Apple Home supports basic device functions only
  • Advanced KNX logic stays in Homey or the KNX system
  • KNX devices remain fully functional without Apple Home
  • Removing a device from Homey also removes it from Apple Home

Use Apple Home for control and scenes and Homey and KNX for logic and reliability.

In short

KNX devices don’t connect to Apple Home directly.

Homey bridges KNX to Apple Home by translating KNX functions into smart home accessories Apple Home understands.

Apple Home becomes a simple, familiar way to interact with it and Homey stays in control of the KNX system.
