Smart Home Automation Cost in India (2026): Real Price Guide

Modules go behind your existing switch plates and join your home WiFi. The switches still work by hand, the app becomes a second way to press them. No rewiring, no civil work, a 2 to 3 BHK done in under a week. This is the tier for finished homes, rented flats, and anyone testing whether automation is for them.

• Cheapest true entry, and the only tier that suits a rental
• Onwords own WiFi product lineup, so hardware and support are one team
• App control and schedules, not a home that acts on its own
• Past roughly 40 loads, reliability starts to wobble

Devices talk on their own low-power radio instead of fighting your router, and every mains device relays for its neighbours. Premium touch panels go on the wall. This is where Living Home OS enters, which is the point at which the house stops waiting for taps and starts making decisions.

• Dedicated radio mesh, battery sensors that last years
• Living Home OS: presence, schedules, home AI, local control offline
• Higher cost per point, and a hub is mandatory
• Still radio, so thick or metal-heavy structures need planning

A dedicated bus cable runs to every switch, sensor and panel, and the devices talk over that wire. No radio in the path, no router in the path. KNX is an open worldwide standard, so a dimmer from one brand works with a sensor from another and you are never trapped with a single vendor. It is a 30-year decision made in a two-week wiring window.

• Independent of WiFi and internet, rock solid at high load counts
• Open standard, multi-vendor, no lock-in for three decades
• Cable must be pulled before plastering, so it is a new-build decision
• Engineering and programming labour sits visibly in the quote

One brand supplies processors, touchscreens, keypads, shading motors and the AV distribution that pushes video and audio to every room, and a certified dealer programs the interface around your family. Onwords is an authorized Crestron dealer. Below about ₹25 lakh, KNX and Z-Wave give you more per rupee, and we will say so.

• One interface for AV, lighting, shading and climate
• Cinema-grade rooms and whole-home video distribution
• Dealer-programmed, changes go through a programmer
• Single-brand ecosystem, which is the price of everything matching

Point count, not carpet area

Cost scales almost linearly with controllable points. A 1,500 sq ft flat wired with 30 circuits and one wired with 60 circuits are two entirely different quotes. Before you compare vendors, fix the point count so you are comparing the same house.

Wired versus wireless

Wired KNX costs roughly three to five times per point what WiFi retrofit costs, and buys you three decades instead of one. If the walls are open, the cable is cheap. If the walls are closed, wired means demolition, and the civil bill can rival the automation bill.

Brand and finish tier

The same function in a plastic module and in a glass touch panel with a machined metal frame can differ by four times. Switch plates are the jewellery of a smart home, and they are where budgets quietly inflate. Decide the finish before you decide the tier.

Lighting design

Scene lighting needs more circuits, dimmable drivers and often DALI or 0-10V control. A room designed for four moods costs more to automate than a room with one ceiling light, and the fixtures themselves are a separate budget line that automation does not include.

A wireless smart home is only as good as the WiFi under it. A single ISP router does not cover a villa, and a crowded 2.4 GHz band is the most common cause of a house that "keeps disconnecting". Proper access points, cabling and a separate network for devices are a genuine cost that most quotes silently skip and later blame.

Many older Indian homes ran only live and switch wire to the board, with no neutral at the switch box. Most retrofit modules need that neutral. Either an electrician pulls it in, or the design shifts to no-neutral modules that carry their own compromises. Find out at survey stage, not on installation day.

Any wired system in a finished house means chasing walls, laying conduit, then plastering, priming and repainting. On a KNX retrofit that civil work commonly adds 15 to 25 percent to the automation cost. During construction it is close to zero, which is the whole argument for deciding early.

Onwords products carry a five-year warranty, which covers most of a Tier 1 or Tier 2 home. Third-party hardware runs on its own manufacturer terms. On large wired systems, an annual maintenance contract typically prices at 5 to 10 percent of hardware value. A cheap installation with an expensive AMC is not a cheap system.

You are buying convenience

Phone and voice control, schedules, and never walking back to check whether the geyser is off. That is worth the money on its own, and it is reversible. The devices move house with you.

You are buying a home that decides

Living Home OS arrives here. Presence lighting, AC schedules that learn, leak and gas alerts, and automations that keep running locally when the internet is down. This is the tier where automation stops being a gadget.

You are buying infrastructure

Wired KNX is part of the building, like plumbing. It outlives phones, routers, apps and usually the first owner. Priced across fifteen years it is often cheaper than replacing a wireless system twice.
