Akubela Aura Series K32-B4-EU KNX 4-Button Smart Switch with OLED Display

Akubela Aura Series K32-B4-EU KNX 4-Button Smart Switch

The Akubela Aura Series K32-B4-EU is a premium KNX wall switch that pairs a flat, glass-fronted design with genuine smart building functionality. As part of Akubela's modular Aura Series, this 4-button panel connects directly to any standard KNX installation for dependable, wired control of lighting, shading, HVAC and scenes, and can also be linked through an Akubela HyPanel gateway to extend control to non-KNX smart home platforms. It is a great fit for architects, integrators and homeowners who want a refined switch that still behaves like a serious automation device.

Its flat-glass aesthetic and reconfigurable OLED labelling make it especially useful in multi-purpose rooms, master suites and living areas where scene names or button functions change over time, while its built-in sensors help streamline climate automation without additional in-wall devices.

Frequently Asked Questions

Does the K32-B4-EU need its own power supply?
No. It draws power directly from the KNX bus, so no separate transformer or mains wiring is required at the switch itself.

Can this switch work with non-KNX smart home systems?
Yes. While it connects natively to any KNX installation, linking it through an Akubela HyPanel gateway extends control to compatible non-KNX smart home platforms.

Do I need to engrave or print labels for the buttons?
No. Each button has its own OLED display that shows editable icons or text, which can be changed anytime through the BelaHome app.
