Run Smart Home Wiring
Wi-Fi handles many smart home devices, but hardwired connections are faster, more reliable, and future-proof. Running Cat6 ethernet, speaker wire, and low-voltage power to window headers while walls are open costs a fraction of what it would after drywall goes up, and you'll never regret having the infrastructure.

Essential Runs to Install
Cat6 ethernet to the media wall
Run at least two Cat6 ethernet cables behind the TV location: one for a streaming device or smart TV and one for a gaming console. A hardwired connection eliminates buffering, reduces latency, and doesn't compete with other devices for Wi-Fi bandwidth. Terminate at a keystone wall plate for a clean look.
Speaker wire for in-ceiling or in-wall speakers
Run 16-gauge (or 14-gauge for longer runs) speaker wire from your equipment location to each speaker position. For a 5.1 surround setup, that's five speaker locations plus a subwoofer feed. Label every wire at both ends before closing walls. Use CL2-rated wire for in-wall installations per code.
Power and control wire at each window
Motorized shades and blinds need power at the window header. Run a 14/2 Romex line (or low-voltage wire for battery-powered motors) to a recessed outlet or junction box in the ceiling or window frame above each window. This is nearly impossible to add after drywall without visible conduit.
Run conduit for future-proofing
Install 1-inch flexible conduit (smurf tube) between the media wall and the structured wiring panel. This empty pathway lets you pull new cables in the future without opening walls. Run conduit to at least 2-3 key locations: behind the TV, to the equipment closet, and to the Wi-Fi access point location.
Structured Wiring Panel
- What it is: A central panel (usually in a utility closet or basement) where all low-voltage wiring terminates. Think of it as the nerve center for your smart home. Every Cat6, coax, and speaker wire home-runs back to this panel.
- Panel sizing: A 28" or 42" structured media enclosure (Leviton, On-Q) mounts in the wall between studs. Choose one large enough to hold a network switch, patch panel, and power strip with room to spare.
- Network switch: An 8-port or 16-port gigabit switch connects all your ethernet runs. Managed switches let you create VLANs and prioritize traffic for streaming.
- Power to the panel: Run a dedicated 20-amp circuit to the structured wiring panel location. Your router, switch, and any PoE (Power over Ethernet) devices need reliable power.
Smart Home Devices to Pre-Wire For
- Wi-Fi access point: Run a Cat6 cable to a central ceiling location for a dedicated access point. This provides far better coverage than a router tucked in a closet.
- Smart lighting switches: Most smart switches need a neutral wire in the switch box. Verify your electrician is running neutral wires to every switch location during the rewire phase.
- Motorized shades: Power at the window header (covered above) plus a control wire if using a hardwired shade controller rather than Wi-Fi or Zigbee.
- Security cameras: If you want an interior camera, run Cat6 to a discreet corner location near the ceiling. PoE cameras get power and data through the single ethernet cable.
- Voice assistant location: Run power and ethernet to a built-in shelf or wall niche where a smart speaker or display will live permanently.
Pro Tips
- •Label everything obsessively: Label both ends of every cable with a unique identifier (e.g., "LR-ETH-1" for living room ethernet run 1). Create a spreadsheet mapping each label to its location. You will thank yourself years later.
- •Run more than you think you need: Cable is cheap; labor is expensive. If you think you need one ethernet drop behind the TV, run three. An extra Cat6 run costs $20-$40 in materials while walls are open.
- •Keep low-voltage and high-voltage separate: Ethernet and speaker wire should run at least 12 inches away from electrical wiring to avoid interference. When crossing electrical lines, cross at a 90-degree angle.
