Neutral wires, smart dimmer compatibility, hubs, camera power and structured cabling — a plain-English guide to smart home wiring from a Texas home automation electrician.
Smart switches are the easiest win in home automation — until you open the box and discover there's no neutral wire. Here's what to sort out first.
Most smart switches need a neutral at the switch box. Homes from the 1980s and earlier often don't have one. A smart home electrician can pull a neutral or install no-neutral switches like Lutron Caséta.
Match the dimmer to the bulb type to avoid flicker and buzz. We test every circuit before leaving.
Video doorbells need a 16–24V transformer; many older ones are too weak. PoE cameras need Cat6 runs back to a switch.
If you're remodeling, run Cat6 to every TV location and office now — it's cheap while walls are open.
