What does it cost to have smart home devices installed?
Smart home device installation costs $0 for battery-powered devices you mount yourself to $150–$800+ when hardwiring or electrical work is involved. The dividing line is simple: battery-powered and plug-in devices are DIY. Hardwired devices — Ring doorbells that need transformer power, smart switches that need a neutral wire, in-wall speakers, permanent cameras — usually need an electrician.
The most common surprise cost: smart light switches in homes built before the mid-1990s often lack a neutral wire in the switch box. Without neutral, most smart switches won't work — and the workaround (a Lutron Caseta or a neutral wire add) costs $150–$250 per switch location.
Device by device: what the install actually costs
| Cause | How to tell | The fix | Typical cost |
|---|---|---|---|
| Smart thermostat (Nest, Ecobee, Honeywell) | Replacing an existing programmable or manual thermostat — most systems have compatible wiring already | Most homeowners install these themselves in 30–60 minutes; an electrician is needed if there's no C-wire and the workaround adapter doesn't work with your HVAC system | $0 DIY; $150–$300 if pro install needed |
| Ring / Nest doorbell (hardwired) | Replacing an existing wired doorbell; Ring Video Doorbell Pro and Pro 2 require 16–24V AC power from a compatible transformer | If existing transformer is compatible: straightforward swap a confident DIYer can handle. If transformer needs upgrading or no existing doorbell: electrician required to run new wiring | $150–$300 (electrician, if needed) |
| Smart light switch (single location) | Replacing standard wall switch with a Caseta, Kasa, or similar smart switch | DIY if there's a neutral wire (white wire in switch box). Most modern homes (built after 1985–1990) have neutral. Older homes may not — requires either a no-neutral-required switch (Caseta) or an electrician to run neutral | $0 DIY (with neutral); $150–$250 per location (electrician if no neutral) |
| Security cameras — battery or plug-in | Ring Stick Up Cam, Arlo, Wyze Cam battery or plug-in models | True DIY: mount with included hardware, connect to WiFi. No electrician needed. Power outlet within range is all that's required. | $0 (self-install) |
| Security cameras — wired / PoE | Installing a permanent wired camera system (NVR with PoE cameras, or cameras that need in-wall Ethernet runs) | Requires running Cat6 cable through walls and attic to a central NVR — this is a low-voltage installer or electrician job for anything beyond a single visible surface run | $200–$600 per camera location (professional install) |
| Smart home hub or whole-home setup | Installing a full system — smart switches throughout, smart locks, hub, whole-home lighting control | Requires licensed electrician for all switch work; smart home integrator for hub programming and device pairing | $1,500–$5,000+ depending on scope |
Before you call anyone
- Check for a neutral wire before buying smart switches: turn off the breaker, remove the switch cover, and look for a bundle of white wires in the back of the box. If you see it, most smart switches will work. If there's only black, red, and bare copper, you're in a no-neutral situation — buy Lutron Caseta or plan for an electrician.
- For a Ring or Nest doorbell replacement, check your existing doorbell transformer's voltage before buying. The transformer is usually near the main panel or in a utility area. Ring Video Doorbell Pro requires 16–24V AC. Most transformers from 2000+ are compatible; some from the 1980s run at 10V and need an upgrade.
- Battery-powered smart home devices (Arlo cameras, Ring battery doorbells, smart locks, most sensors) are genuine DIY and install in under an hour each — save your electrician budget for the hardwired stuff.
- Smart plugs and plug-in smart switches (for lamps, appliances) are the easiest entry point for smart home automation — they work in any standard outlet with no wiring knowledge required.
Call a pro when…
- Your smart switch installation reveals no neutral wire in the switch box and your chosen device requires one — an electrician can run a neutral or recommend a compatible no-neutral device
- Your Ring doorbell Pro or hardwired camera requires new wiring that needs to run through walls or the attic — low-voltage wiring through finished walls is a pro job
- You want smart switches in a home with aluminum wiring (common in homes built 1965–1975) — aluminum wiring requires CO/ALR rated devices and should be handled by a licensed electrician
- Anything involving the main panel — adding a dedicated circuit for a smart home hub, EV charger, or whole-home audio system needs a permit and a licensed electrician
DIY or hire an electrician?
The honest breakdown: battery-powered and plug-in smart devices are DIY for any homeowner comfortable following an app-guided setup. Hardwired devices are sometimes DIY (smart thermostat, compatible doorbell swap) if existing wiring is compatible and you're comfortable turning off a breaker and making a few wire connections. New wiring, no-neutral switch situations, and anything involving the panel always need a licensed electrician. A single electrician visit to handle several smart switch locations at once ($300–$600) is far more cost-effective than four separate calls — make a list of everything hardwired before you book.

Related questions
Do I need an electrician to install a Ring doorbell?
It depends on the model. Battery-powered Ring doorbells (Ring Video Doorbell, Ring Video Doorbell 4) are pure DIY — mount, connect to WiFi, done. Hardwired Ring models (Ring Video Doorbell Pro, Pro 2, Elite) require existing doorbell wiring with a compatible transformer, and may need an electrician if your transformer is underpowered or you have no existing doorbell.
Why won't my smart switch work without a neutral wire?
Smart switches need a small continuous current to power their WiFi radio and processor even when the light is off. Traditional switches don't need that — they're just an open or closed circuit. The neutral wire provides the return path for that tiny current. Without it, many smart switches will flicker, buzz, or not work at all. Lutron Caseta uses a different communication protocol (Clear Connect radio) that doesn't require neutral — it's the most reliable no-neutral solution and is compatible with most modern dimmers.
How much does a smart thermostat installation cost with an electrician?
If your existing wiring is compatible (which it usually is for homes built after 1980 with central forced air), electrician-installed smart thermostats run $150–$300 for the visit. Most thermostats work on existing low-voltage wiring; the only time you need real electrical work is if there's no C-wire (common wire) and the add-a-wire adapter doesn't work with your HVAC.
Is a handyman or an electrician better for smart home installs?
A handyman can handle the mounting and app-setup of battery-powered and plug-in smart devices — cameras, smart plugs, smart locks, video doorbells with existing compatible wiring. For anything involving opening a switch box, running wires, or touching your electrical panel, you want a licensed electrician. The license matters for safety, but also for insurance — if an unpermitted installation causes a fire or fails inspection at resale, the work has to be redone.
