Why KNX instead of a proprietary system?
KNX is an open standard (ISO/IEC 14543-3), so certified devices from different manufacturers work on one bus and one engineering tool. Service and extension are not tied to a single supplier.
Products we supply
KNX Building Automation
KNX and DALI lighting, blinds, HVAC and access control on one open building bus, designed, programmed and commissioned by Powersense.
01Overview
Supply and engineering from one team
Powersense supplies KNX actuators, sensors, touch panels, gateways and power supplies, and engineers the installation: topology, group-address structure, scenes, schedules, programming in ETS and commissioning.

06Technical notes
Technical notes and FAQ
Does KNX replace DALI?
No. DALI controls luminaires and drivers within a room. KNX integrates lighting with blinds, climate and access across the building, linked by a gateway.
