What a smart home costs in Singapore
Short answer: S$50 per device to install and S$40 per device to integrate, plus a S$500 or S$1,000 consultation (HDB/condo vs landed, shophouse, commercial). All before GST, and you buy the hardware yourself. No monthly platform fees when it runs locally on Home Assistant.
| Setup | Typical price | What you get |
|---|---|---|
| Installation | S$50 per device | Physical installation of each device (before GST) |
| Integration | S$40 per device | Connecting each device into Home Assistant, KNX or Aqara / Smart Life / Broadlink (before GST) |
| Consultation (HDB/condo) | S$500 | Planning, system design, up to 2 site visits (before GST, offset against final project cost) |
| Consultation (landed/shophouse/commercial) | S$1,000 | Planning, system design, up to 2 site visits (before GST, offset against final project cost) |
| HDB / BTO project, whole budget | S$1,000 to S$10,000 | Depends on unit size and requirements. Includes hardware such as smart switches, IR blasters, motorised curtains and smart locks (before GST) |
| Condo project | Slightly more than HDB / BTO | Condos usually have a balcony that needs Ziptrack installation |
| KNX project | S$50,000 to S$100,000 or above | Design, planning, cabling and top-tier hardware, designed to last more than 10 to 20 years. Generally used in commercial projects and hotels for long-life hardware and 100% local control (before GST) |
Every home is different. All prices are before GST; exact quotes follow a paid project consultation. The consultation fee can be fully offset against the final project cost. It covers project scheduling and planning, smart home system design, up to 2 site visits, guidance for electricians on electrical requirements, Wi-Fi and CCTV planning, and site inspection with technical recommendations.
What actually drives the price
Rooms and device count
Each room adds switches, sensors, and configuration time. A 2-room starter costs a fraction of every-room coverage.
Who buys the hardware
Buying it yourself is the cheaper option: most hardware is widely available on Shopee or Taobao.
Hub choice
Home Assistant generally costs more up front: Home Assistant Green is about S$240, plus a Zigbee module at about S$20 to S$30, against about S$20 for a Smart Life Zigbee hub. These are approximate market prices.
Wired vs wireless
Smart switches need a neutral wire; curtain tracks may need new power runs. Retrofit wiring is the most variable line item — during renovation it's far cheaper.
Aircon integration
Bringing every split unit under automation (schedules, room-by-room control, live status) adds per-unit hardware — and is usually the upgrade owners use most in Singapore's climate.
WiFi and CCTV scope
Whole-home WiFi and 4K CCTV are often bundled into landed projects and scale with floor area.
Doing a new flat? See the BTO smart home package guide — wiring decisions made during renovation are the single biggest money-saver. For aircon-first setups, see automated climate control.
