Home automation in India costs anywhere from ₹40,000 for a basic WiFi-based setup in a 2BHK to ₹1,00,00,000 and above for a fully KNX-integrated luxury villa. For most homeowners, the practical range is ₹5,00,000 to ₹20,00,000 for a properly wired, scene-controlled apartment or 4BHK. The reason the range is so wide is that "home automation" means very different things at different budgets — and most quotes don't make that clear.
At TechVault, we design and install KNX-based automation across Delhi NCR, Noida, Gurgaon, and Jaipur. This guide breaks down what home automation actually costs in India — by home size, by system type, and system by system — so you can work out where your project realistically sits.
What Actually Decides the Cost?
Four things move the number more than anything else:
Home size — more rooms means more switch points, more actuators, more programming. Cost scales with points, not square feet.
System type — a WiFi-based setup and a KNX system can control the same lights, but they are separated by roughly 5-10x in cost because one is plug-and-play hardware and the other is designed, wired, and programmed infrastructure.
How many systems you automate — lighting alone is very different from lighting plus climate plus curtains plus security plus AV.
New construction or retrofit — retrofitting typically adds 30-50% because cabling has to be run through finished walls and ceilings.
What Does Home Automation Cost by Home Size?
| Home Size | WiFi-Based System | KNX Scene-Based System | KNX + DALI Professional |
|---|---|---|---|
| 2BHK Apartment | ₹40,000 – ₹1,20,000 | ₹5,00,000 – ₹12,00,000 | ₹8,00,000 – ₹16,00,000 |
| 3BHK Apartment | ₹60,000 – ₹2,00,000 | ₹8,00,000 – ₹20,00,000 | ₹12,00,000 – ₹26,00,000 |
| 4BHK Villa | ₹1,00,000 – ₹3,50,000 | ₹15,00,000 – ₹40,00,000 | ₹22,00,000 – ₹55,00,000 |
| Large Villa / Farmhouse | Not practical at this scale | ₹40,00,000 – ₹1,00,00,000+ | ₹60,00,000 – ₹1,50,00,000+ |
These cover full-home automation — lighting, climate, curtains, security, and control — not lighting alone. All figures are indicative estimates; actual pricing requires a site assessment.
What's the Difference Between These Three Tiers?
The gap between ₹1,00,000 and ₹15,00,000 confuses most people, so here is what you actually get at each level:
| WiFi-Based | KNX Scene-Based | KNX + DALI | |
|---|---|---|---|
| Control | On/off and basic dimming via app | Full scenes across all systems | Scenes plus per-fixture dimming and colour |
| Works without internet | Mostly no | Yes | Yes |
| Wiring needed | None | Dedicated bus cable | Bus cable plus DALI drivers |
| Dimming quality | Can flicker at low levels | Smooth | Smooth from 0.1% to 100% |
| Coordinates with climate, curtains, AV | Limited | Yes | Yes |
| Typical lifespan | 3-5 years | 25-30+ years | 25-30+ years |
| Best for | Renters, single rooms, testing | New builds, renovations | Luxury homes, architect-led interiors |

What Does Each System Cost Separately?
Most homeowners don't automate everything at once. Here is what each system costs on its own, so you can plan in phases:
| System | Approx. Cost | Notes |
|---|---|---|
| Lighting automation | ₹2,50,000 – ₹15,00,000 | Usually the first and largest component |
| Climate / HVAC control | ₹80,000 – ₹4,00,000 | Depends on the number of AC zones |
| Curtain & blind automation | ₹25,000 – ₹80,000 per window | Motor, track, and control per opening |
| Security & surveillance | ₹1,50,000 – ₹8,00,000 | Cameras, sensors, alarm panel |
| Digital locks | ₹25,000 – ₹1,50,000 per door | Varies widely by brand and features |
| Networking infrastructure | ₹80,000 – ₹5,00,000 | Structured cabling, switches, access points |
| Multi-room audio | ₹1,50,000 – ₹8,00,000 | Scales with number of zones |
| Home theatre | ₹3,00,000 – ₹35,00,000+ | Separate project in its own right |
For detailed breakdowns of the two largest components, see our lighting automation cost guide and home theatre cost guide.
What's Included in a Quote - and What Isn't?
This is where most confusion and most budget overruns come from.
| Usually Included | Usually Quoted Separately |
|---|---|
| KNX bus cabling and conduit | Light fixtures, downlights, LED strips |
| Actuators (dimming, relay, blind) | Main electrical wiring and DB |
| Keypads and sensors | False ceiling and civil work |
| ETS6 programming and commissioning | Interior design and carpentry |
| Scene setup and testing | AC units themselves (only control is included) |
| ETS project file handover | Curtains and fabric (only motors included) |
| Warranty and initial support | Annual maintenance after warranty |
Always ask for an itemised quote that separates automation hardware, fixtures, labour and programming. It's the only way to compare two integrators honestly — a lower headline number often just means fewer things included.
Which Brands Affect the Cost Most?
The keypad is the single most visible cost variable in a KNX system. The underlying logic is identical regardless of brand, but the interface hardware changes the budget significantly:
| Keypad Brand | Approx. Price Per Keypad |
|---|---|
| CORE | ₹18,000 – ₹50,000 |
| ABB | ₹20,000 – ₹65,000 |
| Basalte | ₹35,000 – ₹90,000+ |
Across a 4BHK with 15-20 keypads, that alone can shift the total by ₹10,00,000. We cover the differences in detail in our Basalte vs ABB vs CORE comparison.
An example: 4BHK Villa in Sector 50, Noida
A 4,200 sq ft villa where the owner wanted the full home on one system. Itemised:
| Component | Cost |
|---|---|
| KNX lighting automation — 14 zones, actuators, keypads, DALI-2 drivers, ETS6 programming | ₹8,92,000 |
| Climate control integration — 5 AC zones | ₹1,85,000 |
| Curtain automation — 11 windows | ₹4,40,000 |
| Security and surveillance | ₹3,20,000 |
| Digital locks — 3 doors | ₹1,35,000 |
| Networking — structured cabling, switches, access points | ₹2,40,000 |
| Multi-room audio — 6 zones | ₹4,50,000 |
| Total automation scope | ₹26,62,000 |
Light fixtures, false ceiling work, and the AC units themselves were outside this scope, quoted by the interior contractor. The homeowner interacts with six whole-home scenes from a keypad at the entrance: Morning, Day, Evening, Dinner, Sleep, and Away.
Figures are indicative for a project of this scope and finish level, not a fixed quotation.
Can You Do It in Phases?
Yes — and for most budgets this is the sensible approach. The important thing is that the wiring goes in during construction, even if the devices don't.
A workable phasing:
Phase 1 (during construction): KNX bus cable and conduit throughout, plus lighting automation. This is the phase you cannot postpone — running bus cable later means opening walls.
Phase 2: Curtains and climate control. Both add heavily to daily comfort and integrate into existing scenes.
Phase 3: Security, networking upgrades, multi-room audio.
Phase 4: Home theatre, if it's part of the plan.
Because KNX is an open standard, devices added in later phases join the same system and appear in the same app and keypads. Nothing needs replacing.
What Pushes the Cost Up?
- Retrofitting instead of pre-wiring — 30-50% more for the same result
- High keypad count — every additional control point adds hardware and programming
- Premium keypad brands — the largest single variable
- DALI-2 across all fixtures — worth it for large or design-led homes, unnecessary in many apartments
- Complex scene logic — more conditions and triggers means more programming hours
- Multiple floors — additional bus lines and couplers
What Can You Save On - and What Shouldn't You?
Reasonable to economise on: keypad brand in secondary rooms and corridors, DALI-2 in areas where basic dimming is enough, phasing non-essential systems to later, and the number of scenes at handover — more can always be programmed later.
Not worth cutting: bus cabling and conduit during construction, quality of the actuator panel, and the commissioning and programming time. Those three determine whether the system works properly for twenty years or frustrates from month one.
And if the honest answer for your situation is a ₹1,00,000 WiFi setup rather than a ₹15,00,000 KNX system, that's a legitimate outcome. We'd rather scope correctly than oversell — a well-chosen wireless system in a rented 2BHK is a better decision than an underfunded wired one.
FAQs
What is the minimum budget for home automation in India?
A basic WiFi-based setup with smart switches and app control starts around ₹40,000 for a 2BHK. For a wired, scene-controlled KNX system, a realistic entry point is around ₹5,00,000 for a 2BHK covering lighting and basic integration.
Is KNX worth the extra cost over a WiFi system?
It depends on the home. For a rented apartment or a single room, WiFi is usually the better decision. For a home you're building or renovating and plan to live in long-term, KNX costs more upfront but works without internet, coordinates every system, and typically lasts 25-30 years rather than 3-5.
How much does home automation cost for a 3BHK flat?
A WiFi-based setup runs ₹60,000 to ₹2,00,000. A KNX scene-based system for a 3BHK typically ranges from ₹8,00,000 to ₹20,00,000 depending on point count, keypad brand, and how many systems are included.
Does home automation cost more in an existing home?
Yes, typically 30-50% more. Cabling has to be routed through finished walls and ceilings, coordination with other contractors is harder, and some options simply aren't available once construction is complete.
What ongoing costs should I budget for?
An annual maintenance contract typically runs ₹15,000 to ₹50,000 per year depending on system complexity, covering scene changes, software updates, and support. The initial installation includes a warranty and support period.
Can I add more automation later without redoing everything?
Yes, provided the bus cabling was run during construction. KNX is an open standard, so new devices join the existing system and appear alongside everything else. This is the main reason we recommend wiring generously even on a phased budget.
