What is KNX?
KNX is the only globally recognized standard for home and building automation. KNX is the name of a communication protocol that can be used to automate and link installations and devices. This concerns many different types of installations; from audio to video and from lighting to heating. Virtually every installation can be 'made smart' via KNX, making it linkable with other KNX installations.
KNX is built into all components and systems of manufacturers that have joined KNX. Products from KNX manufacturers can therefore be interconnected, regardless of which manufacturer has produced these products. This ensures future-proof systems with more freedom of choice for clients and end users. Thanks to the KNX protocol, an installer and system integrator such as Vermeulen who can work with KNX can forge the KNX-certified components and systems into one whole.
