Wiring a Home for Automation
Wireless smart devices work in any home, but a little pre-wiring makes automation more reliable and easier to expand.
Updated 2026-10-15
Pre-wire checklist
During new construction or a major remodel:
- Neutral conductor in every switch box
- Deep boxes at switch banks and keypads
- Cat6 to TVs, offices, access points, and cameras
- Conduit from the network closet to attic and basement
- Power and data for doorbells, locks, and shade motors
- A ventilated network/AV location near the panel
Centralized vs device-based
Centralized lighting systems run switch loops back to a panel of dimmers, which suits high-end installs. Device-based systems use smart switches at each location and are more common. Decide early, since wiring differs.
Who does what
Electricians handle line-voltage work; low-voltage contractors or integrators handle networking and AV. Coordinate both early so boxes and pathways match the plan.

Frequently asked questions
Is Wi-Fi enough for smart home devices?
Many devices use Wi-Fi, Thread, or Zigbee. Solid wired access points improve reliability for all of them.
Should I wire for cameras even if I don't install them now?
Yes. Running cable during construction is inexpensive compared to retrofitting.
Do smart panels count as home automation?
They add circuit-level monitoring and control and integrate with solar, batteries, and EV chargers.
