Smart home installation: what to know

What the job involves, what changes the price, and what to ask a pro.

What smart home installation is

Smart home installation sets up connected devices such as lighting, thermostats, locks, cameras and voice controls, links them to one hub or app, and checks that they work together. People hire it when the devices they bought do not talk to each other, the Wi-Fi drops, or they want routines that run without fuss.

Signs you need it

  • You have several smart devices, but each one uses a different app and none of them work together
  • Devices drop off the network, go offline or respond slowly in some rooms
  • You want lights, the thermostat and the locks to follow a daily routine
  • You want voice control that reliably runs the lights, locks and thermostat
  • You bought a smart thermostat or smart switches and need them installed and set up

What the pro does

  • Survey the home and the Wi-Fi coverage, and pick the hub or protocol that suits the devices
  • Place the access points, mesh nodes or hub so each device has a solid connection
  • Install the smart switches, thermostat or bulbs, using a licensed electrician where the local rules call for one for wall switches or line voltage
  • Pair each device to the hub or app, then update its firmware to the current version
  • Build the routines and scenes, such as lights on at sunset, locks checked at night and the thermostat set for the day
  • Test each device and routine, then show the owner how to change routines and add new devices

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • Number of devices and the mix of brands, since mixed systems take more setup work
  • Wi-Fi coverage in the home, and whether mesh nodes or access points are needed
  • Whether a hub is needed, and which protocol the devices use
  • Wall switches that must be replaced with smart switches, which involve line voltage work
  • Integration with existing systems such as the thermostat, the alarm or the lock
  • Number of routines, scenes and voice assistant setups the owner wants
  • Access to the attic, crawl space or wall cavities where wiring or nodes must go

What a written quote should spell out

  • Each device listed by brand, model and quantity
  • The hub, mesh nodes or access points, and where they will be placed
  • Any smart switch or thermostat wiring listed as a line for the licensed electrician
  • Setup, pairing, firmware updates and routine building, shown as separate lines
  • Voice assistant integration, and which accounts the owner must provide
  • Warranty on the devices and the labor, and who handles device faults

Questions to ask before you hire

  • Which hub or platform do you recommend, and why does it suit my devices?
  • Will my Wi-Fi reach every device, or do I need mesh nodes?
  • Which of the switches need a licensed electrician to change?
  • Who owns the accounts and passwords for the devices and the hub?
  • What happens if the internet goes down, and which routines still work?
  • Will you set up the routines I ask for, and show me how to change them?
  • What warranty covers the devices, the hub and the labor?

Red flags

  • They set up devices under their own accounts and will not transfer them to you
  • They pick a platform without asking which devices you already own
  • They skip the Wi-Fi check, then blame the devices for drops
  • They replace wall switches without checking whether your area requires a licensed electrician
  • They leave the routines untested or untrained

What you can do yourself

A homeowner can plug in smart plugs, install battery-powered sensors, and set up apps and routines after the pro finishes. Do not replace wall switches, change the wiring behind a switch, or work in a panel, because those connections are live electrical work and need a licensed electrician. Call a pro for the hub, the Wi-Fi coverage plan, and any wired device install.

Licenses and permits

Smart home installation is often done without a separate license for plug-in and battery devices, but replacing a wall switch or wiring a thermostat to line voltage often requires a licensed electrician. Check with your state or local licensing agency about the work that falls within your scope.

Smart home installation questions

Do I need a hub for smart devices?

Some devices work through their own app or Wi-Fi, while others need a hub for a more reliable connection. Ask the installer which devices need a hub and what the hub does for the system.

Will my smart devices keep working if the internet goes out?

Some devices and routines keep running on a local hub, while cloud-only devices stop until the internet returns. Ask the installer which of your devices work locally and which ones do not.

Can a smart switch be installed without an electrician?

A smart switch that replaces a wall switch involves line voltage, which often needs a licensed electrician. Check your state or local licensing agency about the requirements, and keep that work with the licensed trade.
