One of the most common questions we get at Sedra Electric is simple: “How much does a smart home cost?” The honest answer is that there’s no single number. Your price depends on the size of your space, how many systems you want to control, and the technology you choose (wired KNX vs wireless). This guide breaks those factors down clearly, gives you realistic planning ranges, and shows how to get the most value for your budget.
What drives the price of a smart home
1) Size and number of rooms
The larger the space and the more control points you want (lighting, AC, curtains, switches), the more devices, cabling and labour are involved. A 150 m² apartment is very different from a 400 m² three-storey villa.
2) The systems you include
Lighting control alone costs less than adding climate, motorised curtains, CCTV, multi-room audio, video intercom and EV charging. Each system adds to the cost — and to your everyday quality of life.
3) The technology: wired KNX vs wireless
This is the biggest single factor. We cover it in detail below.
KNX vs wireless: cost and value
| Criteria | KNX (wired) | Wireless |
|---|---|---|
| Best for | Under construction / full fit-out, villas & projects | Already-finished spaces, apartments |
| Upfront cost | Higher | Lower |
| Reliability & lifespan | Very high, long-term stability | Good, depends on the network |
| Future expansion | Very flexible (global standard) | More limited |
Approximate price ranges (for planning only)
These are illustrative tiers for planning. The final price is set after a site visit and defining the exact systems:
| Package | Typically includes | Suited to |
|---|---|---|
| Starter | Lighting control + a few smart points + mobile app | Small/medium apartment |
| Mid | Lighting + climate + curtains + scenes + voice control | Large apartment / duplex |
| Full | All systems + security & CCTV + multi-room audio + intercom + full automation | Villa / palace |

How to save without sacrificing quality
- Plan early: deciding on smart home during fit-out avoids demolition and re-cabling costs.
- Start essential, expand later: choose a scalable system (like KNX) and add systems in phases.
- Focus on daily use: lighting, climate and security deliver the most value.
- Choose a specialist: correct installation prevents faults and future maintenance costs. Read: how to choose a smart home company.

FAQ
Does a smart home raise my electricity bill?
Quite the opposite — proper automation (auto-off, climate control, scenes) helps reduce consumption, and you can add solar for even greater savings.
Can I get a smart home in an already-finished apartment?
Yes, using wireless solutions with no demolition. Sedra determines the best fit after a site visit.
Is maintenance expensive?
Standards-based systems like KNX are highly reliable with minimal maintenance, and professional installation reduces faults.
How long does installation take?
It varies by project size and system type; we define it precisely in the quote after the site visit.
