02 / Automation · KNX TP Bus · Zigbee 3.0 Mesh
01 Two architectures, one experience
A finished Gachibowli apartment and a Kokapet villa at slab stage need completely different automation strategies. Retrofitting wired systems into finished walls means chiselling, dust and repainting. Running a villa with sixty lighting circuits on battery sensors and wireless modules alone can mean compromises on dimming quality and central control.
We design with both. KNX is the open, wired international standard for building automation: a twisted-pair bus cable runs to every keypad and sensor, while DIN-rail actuators in the distribution board switch and dim each circuit. Zigbee is a low-power wireless mesh standard: smart switches and modules fit existing switch boxes and connect to a local hub, with no new cabling.

| Criterion | Zigbee wireless | Wired KNX |
|---|---|---|
| Best stage | Finished homes, retrofits | Pre-plastering, new build |
| Civil work | None — uses existing boxes | Bus cable & DB planning |
| Dimming | Per-channel smart dimmers | DALI / DALI-2, tunable white |
| Interfaces | Smart switches, app, voice | Any KNX brand, touch panels, apps, voice |
| Scale | Apartments, independent homes | Large villas, estates |
| Indicative | ₹1.5–3.5 L (3/4BHK) | ₹4.5–12 L+ (G+2/G+3) |
03 Wired KNX automation
KNX is an open international standard (ISO/IEC 14543) used in homes and buildings worldwide. Because the logic lives on the bus rather than in a single app or cloud service, the system is fast, reliable and independent of any one manufacturer — devices from different brands work together, and any certified integrator can maintain it in future.
That openness is what lets you choose how the home looks and feels to use, room by room, without changing the engineering behind the walls.

04 Zigbee wireless automation
Zigbee 3.0 is a widely used low-power wireless standard built for smart homes. Smart switches and in-wall modules replace or sit behind your existing switch plates, and every mains-powered device also relays signals for its neighbours, forming a self-healing mesh that strengthens as the system grows. Battery sensors for doors, motion and leaks add automation without any wiring.
A local hub runs schedules and scenes inside the home, so everyday control does not depend on the internet. Through the hub, the system works with Alexa, Google Home and Apple devices. Because Zigbee is a standard rather than a single brand, devices from many manufacturers can be combined to suit the budget and the look of each room.
05 Scene lighting
Scenes coordinate lights, curtains, AC and AV together, on KNX or Zigbee. Try three of the most-used scenes in our Hyderabad homes.
Cinema Mode
Evening Lounge
Morning Curtain Open
One tap on a keypad, the app, or "Alexa, cinema mode".
06 Smart lighting
Good automation starts with lighting design: layered cove, downlight, wall-wash and accent circuits that can be dimmed independently. On KNX, DALI and DALI-2 gateways address every driver individually, including tunable-white fixtures that shift from cool daylight to a warm 2700K evening glow. On Zigbee, smart dimmers add scene control and dimming to existing circuits.
We check driver and lamp compatibility before installation, because flicker and hum usually come from mismatched dimmers and drivers — not from the automation system itself.
07 Rooms & devices
Quiet tubular and track motors for sheers, blackouts, Roman and roller blinds. Curtains close automatically for afternoon glare on west-facing Hyderabad façades, and open with your morning alarm. We plan pelmet depth and power points with your interior designer.
Track · Tubular · Schedules
Split and ductable ACs controlled through IR or integration modules, plus geysers, fans and pumps on scheduled or scene-based control. Cool the bedroom before you leave the office; switch off everything with one "Away" tap.
HVAC · Geyser · Schedules
Your home theater and multi-room audio join the same scenes: "Cinema Mode" dims the lights, closes the blackouts, lowers the screen and powers on the projector and AV receiver in sequence.
Cinema · Audio · Projectors
Amazon Alexa, Google Home and Apple Siri control individual devices and complete scenes. Elderly parents can say "good night" instead of learning an app; children get only the rooms you allow.
Alexa · Google · Siri
Motion and occupancy sensors light passages at night at 20%, switch off forgotten bathroom lights, and trigger alerts for water leaks or open doors. Combined with Ajax security, they become part of your home's protection.

08 Engineering details
KNX lines are planned with bus power supplies, line couplers for larger villas, and enough DB space for actuators, DALI gateways and spare capacity. Bus cable runs in its own conduit and is documented so any certified integrator can maintain it later.
We place the hub centrally, make sure mains-powered devices are spread so the mesh reaches every room and floor, and pick a radio channel that avoids congestion from your Wi-Fi. Signal quality is checked device by device before handover.
Many older Hyderabad apartments lack a neutral wire in switch boxes, and shallow boxes limit module choice. We check both on the first visit so the specified Zigbee switches fit and work without surprises.
Automation should work when the internet doesn't. We design for local control at keypads and hubs, then add cloud and voice on a properly engineered EDN network with a dedicated IoT VLAN.
We configure scenes around your routine, label keypads clearly, set app permissions for each family member and staff, and return after two weeks to fine-tune timings once you have lived with the system.

FAQ · Straight answers
Yes. Zigbee smart switches and in-wall modules fit your existing switch boxes and talk to a local hub wirelessly, so a finished 3BHK or 4BHK apartment can be automated without chiselling, rewiring or repainting. Most retrofits are completed within a few days.
If the villa is still before plastering and you want a wired, centrally managed system for many circuits, DALI dimming, curtains and HVAC, KNX is the stronger choice. If walls are finished, or you want lower cost and faster installation, Zigbee wireless is the better fit. Many villas combine both.
KNX is an open standard supported by hundreds of manufacturers, so keypads and switch plates from different brands work on the same bus. We help you choose a range that matches your interiors — glass, metal, wood-finish or minimalist push-buttons — without changing the system behind it.
All three. KNX can be operated from designer wall switches, in-wall touch panels, smartphone and tablet apps, and voice assistants through an IP gateway. You can mix interfaces room by room, for example touch panels in living areas and simple keypads in bedrooms.
As an indicative guide, a Zigbee wireless retrofit for a 3BHK or 4BHK apartment is roughly ₹1.5–3.5 lakhs. A G+2 or G+3 villa with lighting, curtains, HVAC and scenes on KNX or a hybrid system is roughly ₹4.5–12 lakhs or more.
Yes. Scenes and devices can be voice-controlled through Amazon Alexa, Google Home and Apple Siri. Wall switches and keypads keep working locally during an internet outage: KNX logic runs on the bus itself, and Zigbee devices are controlled by the local hub.
