One panel. The whole apartment responds.
Tap a scene. Every circuit, shade, AC zone and AV source shifts at once.

What a scene is, behind the panel.
A scene is the result of 84 control points moving in concert. The hidden engineering — the protocol stack, the failure-mode isolation, the configuration baseline, the in-house programming maturity — is what decides whether the scene works in year three.
Deployment observations
- Scene state is a discrete, named operation on the KNX bus — Welcome, Dinner, Film, Rest, Away, Goodnight — not an ad-hoc transition. Each scene's per-circuit values, transition time and dependency on other systems (HVAC, AV, security) is engineered explicitly.
- DALI handles the lighting bus; KNX TP1 carries scene state and setpoints; Rako Wireless overlays handle retrofit zones — each layer does what it does best, the failure modes localise per layer, the operator sees one keypad UI.
- Six to eight scenes is the practical pattern for a 4 BHK; the family uses two or three daily and the rest cover defined moments. Tuning happens at commissioning against the family's actual rhythm, not at design.
Commissioning discipline
- Scene tuning is a multi-evening exercise with the family at home — empty-house scene programming does not predict the lived-in experience. The transition times, the dimmer endpoints and the AC-zone coordination are walked against actual use.
- Configuration baseline (KNX .knxproj, Rako .pro, DALI gateway config) is exported offline at commissioning and after every change — a panel swap or controller fault is a same-day exercise against the saved baseline.
Operational notes
- Homeowner-app edits cover zone re-allocation and fixture changes without an engineer visit; topology changes route through the practice — the boundary is the rule, not the exception.
- Scene drift after a brand-firmware refresh is a known failure mode — the AMC visit re-validates the scene library against the post-release behaviour and rolls back if the drift is material.
Lifecycle implications
- KNX as the backbone gives the residence a 20+ year operational horizon and vendor independence — any KNX-certified device can replace any other on the bus, with the configuration recoverable from the .knxproj file.
- Rako and Lutron are proprietary and carry vendor-lock over the same horizon; the building owner inherits the brand's roadmap. Each protocol's lifecycle is named in the contract, not assumed from the catalogue.
Expansion readiness
- Additional zones, additional scenes and Phase-2 integrations (security, intercom, BMS) sit on the KNX bus's reserved capacity — the backbone is engineered to hold expansion without re-cabling.
· Why it matters
A scene is not a button — it is the result of 84 control points moving in concert. Lights, shades, AC zones, AV sources, security, intercom. The panel hides the engineering; the engineering is the whole point. KNX as the backbone gives forty-year longevity and vendor independence; Rako handles the wireless retrofit overlays; DALI carries the lighting bus. This module shows what the engineering actually delivers.
· Frequently asked
Whole-home automation —
what people ask first.
Is this a real apartment?
The render is a reference 4 BHK — the scene framework, zone count and protocol decisions are the practice's standard for a residence of this class. We deploy variations of this scene framework across most premium projects.
Why KNX as the backbone instead of Rako-only?
KNX is an ISO 14543 open standard with a forty-year operational horizon and multi-vendor support. Rako and DALI sit as overlays on KNX where retrofit, wireless or specific lighting-bus advantages apply. For a building that will outlive its first integrator, the KNX decision pays itself back many times in the third decade.
How many scenes does a typical 4 BHK actually use?
Six to eight, in our experience. The owner uses two or three daily; the rest cover defined moments — guests, holidays, away mode, sleep. We tune the scene list during commissioning, not at design — what the family actually does dictates the panel, not what an integrator imagines.
Can the scenes be edited after handover?
Yes — without an engineer visit, through the homeowner app. Anything that does not change the underlying topology (zone re-allocation, fixture changes) is handled by the family. Topology changes route through us.
What does the lighting bus look like physically?
DALI 2 wired bus from each ceiling driver back to a central rack, with KNX TP1 carrying scene state and per-zone setpoints. Wireless retrofit zones (where opening up the ceiling was not on the table) sit on Rako Wireless and bridge to the same scene graph through a gateway.
