Smart home wiring is one of the most overlooked yet impactful decisions in Hong Kong renovation. Pre-installing structured cabling during the base construction phase saves 60%+ versus retrofit work and avoids unsightly surface conduits later. The choice of ecosystem — Apple HomeKit, Google Home, Aqara Home or Xiaomi Mi Home — must be locked in before wiring begins, because the location of hubs, switches and PoE drops all depend on it.
AC Design’s eight essential pre-wired points are: 1) low-voltage box with 4x Cat6 trunk lines for Mesh router; 2) entrance for smart lock power, sensor lighting and PoE camera; 3) sofa back hidden outlets and 86mm back-boxes; 4) TV wall HDMI conduit plus one Cat6 for streaming devices; 5) kitchen with integrated cooktop and range hood control wiring; 6) bedside USB-C fast charging, scene switches and curtain motor power; 7) bathroom 16A waterproof outlet for smart bidet plus motion lighting; 8) balcony or work area for smart drying rack and USB low-voltage outlets.
For a typical 600 sqft Hong Kong 2-bedroom flat, entry-level smart home (basic lighting + smart lock + Mesh WiFi) costs HK$15,000–25,000; mid-tier with motorized curtains, voice control and security cameras runs HK$35,000–60,000; flagship KNX or Crestron systems start at HK$120,000. The wiring preparation itself adds only HK$8,000–12,000 to your renovation budget. Three common pitfalls to avoid: single-ecosystem lock-in (use Home Assistant as a unifying hub), insufficient WiFi coverage in reinforced concrete buildings (one Mesh node per 80 sqft), and overloaded circuits when smart bidets share lines with instant water heaters.
