KNX remains responsible for
Dependable field control
- Bus devices and group communication
- Physical switches, sensors and actuators
- Core lighting, climate and shading behaviour
KNX integration
Connect KNX with Home Assistant
Bring KNX controls into useful dashboards and automations while respecting the reliability and design of the underlying building system.

Integrations
Home Assistant can add
A complementary experience layer
- Selected dashboards and visualisation
- Cross-system automation and notifications
- Additional integrations where appropriate
Use cases
Six useful ways the layers can work together
Lighting
Climate
Shading
Scenes
Visualisation
Notifications
Integration architecture
A clear boundary between control layers
The design starts with the KNX topology, group addresses, network connection and operational requirements. Home Assistant is then introduced deliberately rather than placed in the path of essential controls.
Commissioning
Change with control
- 01Inspect topology and responsibilities
- 02Define exposed controls and behaviours
- 03Integrate and test selected functions
- 04Document and commission the completed layer
Controls coexist
Physical controls stay practical
Dashboards should complement appropriate wall controls, not make everyday functions dependent on a screen.
