Feb 2026 7 min

Topology

KNX is a decentralised bus — a single twisted pair runs to every device. No central server, no single point of failure.

Pre-wiring spec

KNX bus cable (JY(St)Y 2x2x0.8) parallel to mains, separated by 50mm. Loop topology with terminators at far ends.

Budget rule of thumb

KNX adds ₹350–600 / sqft to a villa. Includes hardware, wiring, programming and commissioning.
