Smart devices are sold as plug and play. In an older house, they often are not. A little planning saves a pile of returns.
Smart switches need a neutral
Most smart switches and dimmers need a neutral wire in the switch box to power their electronics. Many homes built before the 1980s have no neutral at the switch. An electrician can add one, or you can choose one of the models designed to work without it.
Thermostats need a C-wire
Smart thermostats want constant power from a common wire. If your thermostat cable has a spare conductor, connecting it is simple. If not, a new cable or an adapter is needed.
Video doorbells need a stronger transformer
An old doorbell transformer may not supply enough power, especially in cold weather. See doorbell wiring.
Wire what you can
Wi-Fi is convenient and also the most common point of failure. Cameras, access points, televisions and desktop computers work best on Ethernet. During a remodel or new build, running cable costs little.
Pick an ecosystem
Decide early whether your home will center on Apple, Google, Amazon or a dedicated hub, and buy devices that work with it. Mixing systems is the main reason smart homes feel unreliable.
Think about the panel too
Energy monitors and smart panels show where your power goes and can manage large loads such as an EV charger. If you are planning an electrical panel upgrade, it is a good moment to add them.
Our smart home wiring service covers smart switches, sensors, network cabling and everything in between.
