Should you install your smart home yourself or pay a pro? For most homes the honest answer is: do the easy devices yourself and hire help only for the wiring jobs. That mix usually saves hundreds of dollars without risking a botched electrical job.
This guide breaks down what you can safely DIY, what professional installation actually costs in 2026, how to hire the right installer, and a simple way to decide for each device.

Quick Answer
DIY works well for smart plugs, bulbs, speakers, battery cameras, most smart locks and many video doorbells and thermostats. Hire a pro for in-wall smart switches if you’re not comfortable with line-voltage wiring, new wiring runs, multi-zone HVAC thermostats, hardwired camera systems and whole-home audio or networking. Angi reports labor rates of roughly $50 to $150 per hour for smart home installation.
Which Devices Are Easy, Medium or Pro-Level?
| Device | Typical DIY time | Difficulty | Notes |
|---|---|---|---|
| Smart plug / bulb / speaker | 5 to 10 min | Easy | No tools, just an app |
| Battery camera or doorbell | 15 to 30 min | Easy | A drill for mounting |
| Retrofit smart lock | 20 to 40 min | Easy-Medium | Screwdriver; check door alignment |
| Wired video doorbell | 30 to 60 min | Medium | Low-voltage wiring; may need a new transformer |
| Smart thermostat | 30 to 60 min | Medium | Low voltage; may need a C-wire |
| In-wall smart switch | 30 to 60 min each | Medium-Pro | 120V wiring; often needs a neutral wire |
| PoE camera system | Half a day+ | Pro | Cable runs through walls and attic |
| Multi-zone HVAC, whole-home audio, structured wiring | Varies | Pro | Licensed trades often required |
What You Can Install Yourself
Modern smart devices are built for homeowners. Most come with photo-based in-app guides and compatibility checkers.
Plug-and-play devices
Smart plugs, bulbs, speakers and displays take minutes. If you’re new, start here. Our smart plug guide explains what they can and can’t do.
Smart thermostats
Most thermostats run on low-voltage wiring, so they’re a reasonable DIY job if you take a photo of the old wiring first and turn off power to the HVAC system. The most common snag is a missing C-wire; see smart thermostats without a C-wire and our smart thermostat installation guide.
Video doorbells
Battery doorbells are easy. Wired models connect to your existing doorbell wiring, which is low voltage, but older homes may need a stronger transformer. Our doorbell transformer guide shows how to check yours.
Smart locks
Most smart locks replace a standard deadbolt with a screwdriver. Retrofit models even keep your existing outside key. See our smart lock installation guide for the full walkthrough.
What a Professional Installer Does
A good installer does more than mount devices. Typical services include:
- A home visit to plan devices, wiring and Wi-Fi coverage
- Line-voltage work such as smart switches, done to code
- Running cable for wired cameras, speakers or Ethernet
- Setting up apps, scenes and automations on your platform
- Showing everyone in the house how to use the system
- Follow-up support and warranty on the labor
Who does this work ranges from handymen and electricians to big-box store technicians and custom integrators. For complex whole-home projects, CEDIA is the trade association for smart home professionals and runs a directory of member integrators.
Smart Home Installation Cost Breakdown
Here are current reference numbers from Angi’s 2026 cost guides. Your local prices will vary. To add up devices, labor and monthly fees for your own plan, use our free smart home cost calculator.
| Job | Typical professional cost | Source |
|---|---|---|
| Smart home system (overall) | Average about $768; typical $174 to $1,363 | Angi |
| Thermostat installation | Average about $184; typical $114 to $265 | Angi |
| Doorbell camera, professionally installed | About $150 to $650 total | Angi |
| Labor rate | About $50 to $150 per hour | Angi |
| Pre-installation assessment | About $75 to $300 | Angi |
Also budget for ongoing costs. Camera cloud storage and professional monitoring are often monthly fees. If you’d rather avoid them, see our guide to security cameras without a subscription.
DIY vs Pro: A Real-World Example
Say you want a smart thermostat, a wired video doorbell, a smart lock and four smart plugs. Using the reference figures above:
- All DIY: you pay only for the devices and spend an afternoon.
- Hybrid: you install the plugs and lock yourself and pay a pro for the thermostat and doorbell, roughly a few hundred dollars in labor.
- Full professional: labor for all items plus setup and training, usually the highest cost but zero hassle.
The hybrid route is the sweet spot for most homeowners: you save on the easy jobs and get professional quality where wiring is involved.
The Best Order to Set Up Your Devices
- Network first. Make sure Wi-Fi reaches the front door, garage and backyard before mounting cameras or locks.
- Platform and speaker. Set up Alexa, Google Home or Apple Home so every new device joins the same app.
- Plug-and-play devices. Plugs and bulbs build confidence and let you test routines.
- Thermostat. Usually the biggest money saver; see our best smart thermostat picks.
- Doorbell and lock. Then link them so you can see and unlock from one place.
- Cameras and sensors. Finish with outdoor coverage and leak or motion sensors.
- Routines. Add “leaving home” and “good night” scenes last, once everything is reliable.
How to Decide: A Simple Checklist
Hire a professional if any of these are true:
- The job involves 120V household wiring and you’re not confident turning off the right breaker and testing for power.
- You need new wires pulled through walls, ceilings or the attic.
- Your HVAC system is multi-zone, a heat pump with auxiliary heat, or has unusual wiring.
- Your local rules or your home insurance require licensed electrical work.
- You want everything planned and finished in one visit.
Otherwise, DIY is usually fine. When in doubt, do the plug-and-play pieces yourself and get a quote for the rest.
How to Hire the Right Installer
- Get two or three itemized quotes. Devices, labor hours and any monthly fees should be listed separately.
- Check licensing and insurance for anyone doing electrical work.
- Ask which platforms they support (Alexa, Google Home, Apple Home, SmartThings) and whether they use Matter-certified devices.
- Confirm the labor warranty and how fast they respond to problems.
- Make sure you get the admin logins for every app and device. Your system should belong to you, not the installer.

Common DIY Mistakes to Avoid
- Skipping the compatibility check. Thermostats, switches and doorbells all have wiring requirements. Use the maker’s checker before buying.
- Not labeling wires. Photograph and label every wire before removing the old device.
- Weak Wi-Fi. Cameras and doorbells far from the router disconnect often. Plan coverage with our home network setup guide.
- Too many apps. Pick one main platform first; see what is a smart home for a quick primer.
- Leaving default passwords. Change them and turn on two-step verification.
Frequently Asked Questions
How much does professional smart home installation cost?
Angi puts the average smart home system cost at about $768, with a typical range of $174 to $1,363, and labor at roughly $50 to $150 per hour. Large whole-home projects cost far more.
Can I install a smart thermostat myself?
Usually, yes. Most use low-voltage wiring. Turn off the HVAC power, photograph the wiring and use the maker’s compatibility checker. Call a pro if you have multi-zone or unusual heat pump wiring.
Do smart switches need an electrician?
They involve 120V wiring and many need a neutral wire. If you’re not comfortable working with household wiring, hire a licensed electrician.
Is professional installation worth it?
For wiring-heavy projects, new construction or whole-home systems, yes. For plugs, bulbs, speakers and battery cameras, it’s usually money you don’t need to spend.
How long does a DIY smart home setup take?
A starter setup with a speaker, plugs and bulbs takes under an hour. Adding a thermostat, doorbell and lock usually fills an afternoon.
Will an installer set up my automations too?
Most full-service installers configure scenes and routines. Confirm this in the quote, along with training and after-install support.
Final Verdict
Do the easy wins yourself: plugs, bulbs, speakers, battery cameras and most locks. Pay a professional for anything involving household wiring, new cable runs or complex HVAC. That hybrid approach gives you a reliable smart home at the lowest total cost, and you’ll still understand how everything works.
