How much does it cost to turn the average house into a smart home?

GearBrain talks you through the costs of adding smart tech to every room in your home

Most people's idea of a smart home will be adding a smart speaker or smart home hub that can control basic devices like lights, plugs and perhaps a door lock and security camera.

But what if you want to make your entire home smarter? We're talking about replacing every regular bulb with a smart alternative, swapping out the locks for smart ones, fitting motorized window blinds, and even making the garden more intelligent.

The short answer is, such an ambitious project is not cheap. Even if you live in a small apartment, the cost of lighting alone can run close to $1,000 if you replace every bulb and introduce some mood-setting strip lighting along the way.

What does the average US home look like?

We have chosen a four-bed, two-bath property. According to data released by the Survey of Construction in 2017, this is the most common newly-built U.S. home. Specifically, the data states that houses with four bedrooms or more are the most popular among those built in 2017, accounting for 43 percent. Houses with three bedrooms are next at 41 percent, and the remaining 16 percent had two bedrooms or fewer.

The 2017 data also states the average new-built U.S. home in 2017 had 2.5 bathrooms, which we will round down to two for convenience.

For this article, we are going to address a regular four-bedroom, two-bathroom family home with a separate living room, kitchen and dining room, plus a modest garden and driveway. There is no dedicated home theater or gymnasium to rack up the costs, and we won't be installing a hundred-thousand-dollar sound system for the sake of it.

But if something can be made smart, then it will be. So let's get started.

Smart home hub or smart speaker

Amazon and Google/Nest smart speakers Amazon and Google/Nest smart speakersGearBrain

It is surprisingly cheap to get started on your smart home. All you need is a hub, like the $70 Samsung SmartThings Hub. This can be used as a central controller for all of your smart home devices, like lights, locks, cameras and alarm systems. It connects to devices using Wi-Fi and Bluetooth, plus the smart home standards of Zigbee and Z-Wave.

Alternatively, you can opt for a similarly-priced smart speaker, like the Amazon Echo or Google Home. But because these also include a smart assistant (like Alexa), you will want to install several across the home, so that the assistant can hear you no matter where you are.

Given that, we will budget for one in each bedroom, plus one in the lounge, kitchen and dining room. These could be the $50 Echo Dot or Nest Mini, the $100 Echo, or something more high-end, like the $299 Apple HomePod or $300 Google Home Max.

Assuming a mid-range Echo or Nest speaker in each room, this works out at $700 — or $350 if you opt for cheaper options and hook those up to existing speakers for better sound quality.

How to pick the right smart home hub for you



Lighting

Smart lighting starts at just $20 for a single Mini White bulb from LIFX, which connects to your Wi-Fi and can be controlled with your smartphone or a voice AI like Alexa or the Google Assistant.

But if you want to make the light any color, you will need to spend around $40 to $60 per bulb, depending on which light system you opt for. Options here include Philips Hue, LIFX, Wiz, Sengled, C by GE, TP-Link Kada, and Ikea Tradfri.

According to research conducted in Florida in 2011, the average U.S. household has 47 light bulbs, or around five per room based on the nine-room property we're using as an example. Multiplying this by an average cost of approximately $40 per bulb makes the total cost about $1,880.

Throw in some dimmer switches, motion sensors and $90 LED light strips — which look great under kitchen counters, or behind the television — and an extra $500 on mood lighting and accessories doesn't seem too unreasonable. Now add in some smart lighting for the garden and driveway, and $3,000 comes into view alarmingly quickly.

That said, smart bulbs are all LED so will use far less electricity than the incandescent bulbs you might still be using, so your energy bills will fall. LED bulbs also last far longer, so their high initial cost should spread itself out over the coming years.

Six of the best smart light systems to transform your home

Door locks

August Smart Lock Pro 3rd GenerationSmart locks really streamline the way you move in and out of your home August

Realistically, you only need to purchase two smart door locks to complete your property — one for the front door, and one for the back. Of course, if you want to add some smarts to other doors, then your costs will increase.

One of our favorite smart door locks is the August Smart Lock Pro, which costs $280 and comes with a sensor for letting you know when the door is ajar and not just unlocked. Once installed, a smart lock can be programmed to unlock automatically when you approach it (by recognizing your smartphone), and they can be controlled remotely for letting in the cleaner or an engineer.

Purchasing two of these costs $558 and brings our total to approximately $4,300.

Video doorbell

A great companion for your smart lock is a video doorbell. These look like a regular bell or buzzer, but include a camera, speaker and microphone so you can see and talk to whoever is there — and because they connect to your Wi-Fi and ping your smartphone, you can chat to the visitor whether you are at home or in another country.

August's Doorbell Cam Pro costs $199, while the Ring Video Doorbell Pro is $249 and the Skyball HD is $199. Obviously, you only need to buy one, but expect to spend in the region of $200.

Smart plugs

Picture of TP-Link smart plugSmart plugs are going to be some of the most affordable connected devices you'll buyTP-Link

Smart plugs are a simple and affordable way to make dumb devices smart. Plug a regular heater into one, set up an applet through IFTTT (If This, Then That), and have the heater automatically switch on when the temperature falls below a certain level. The same theory works for fans, air conditioning units, dehumidifiers, and anything else that starts working the moment it is switched on at the wall outlet.

Smart plugs start at a little over $5 each when bought in pack of four. Those from bigger brands like TP-Link are more expensive, in the region of $30 for two. You can also buy smart wall sockets, which offer the same functionality but in a neater package as it's now the outlet itself that is smart rather than a plug added to it. These start at around $25 for an outlet with two sockets.

We'll budget for two pairs of in-wall smart sockets in each room, minus the bathrooms. This means 14, two-socket outlets for a total cost of $350. Some of these outlets also include a pair of USB ports for charging phones and other devices.

Motorized window blinds

Picture of smart blinds in a roomSmart blinds, while tending towards the expensive, are a solid design choiceiStock

This is where things could get expensive again. Along with smart lights, motorized blinds are among the most expensive connected devices to install in your home.

Prices can start at around $300 to $500 per window, but can go every higher depending on the size of each window and the fabric you choose to install. Smart blinds from the Lutron Serena collection are among the most connected, as they work with Amazon Alexa, Google Assistant, Apple HomeKit, Nest, SmartThings, Wink and IFTTT, all via the $80 Caseta Smart Bridge.

The blinds can be scheduled to lower and raise at certain times of day, or you can ask Alexa or Google Assistant to move them with a voice command. Going a step further, IFTTT applets can be configured to close the blinds at sunset (using data from Weather Underground), or close the blinds when you leave home, based on the location of your smartphone.

The average house, according to Lutron, contain 18 windows so you're looking at $6,000 to $7,000 to cover them all with motorized blinds.

A cheaper option to consider is retrofit motors, pictured above, which fit to the wall next to your window and pull on the chain to open and close the roller blind. These cost from around $150 each for devices like the Alexa- and HomeKit-compatible Soma.

Another option comes from Ikea, which now sells the Fyrtur and Kadrilj motorized smart window blinds, which are priced from a far more affordable $129. Choosing Lutron or Ikea is going to make a huge difference to the total cost. Let's assume you want a fully bespoke system (sine the Ikea blinds might not fit all of your windows perfectly), which will cost in the region of $6,500.

How to install motorized blinds: 5 options to consider

Thermostat

Nest Learning Thermostat Nest Learning Thermostat costs $250Nest

A smart thermostat like the Nest or Ecobee is designed to save you money by heating and cooling your home as efficiently as possible. It does this by learning your temperature habits and knowing which rooms are a priority to heat or cool.

Compared to lights and blinds, this is a more affordable device — and one which should save you money on your energy bills. The Nest Learning Thermostat costs $250, while the simpler Next E costs $229, the Ecobee SmartThermostat is $249, and smart options from Honeywell cost around $170.

Larger properties with zoned heating and cooling systems will require a smart thermostat for each zone. For this article and our fictitious four-bedroom home, we'll install two — one for upstairs and one for downstairs — at a cost of $500, plus installation by a professional.

Robotic vacuum cleaner

Is your home even that smart if it doesn't have an army of cleaning robots? If the answer is no, then you'll want to invest in a robotic vacuum cleaner or two.

iRobot and its Roomba range is the market leader, with prices ranging from around $250 to $900. Options from other brands start from just under $100 and head up to $700 for a top-of-the-range model from Samsung. Other brands to consider at the $200 to $500 range include Eufy, Shark and Ecovacs.

For our imaginary home we'll buy two (because, like Daleks, they can't manage the stairs) and set aside $1,000 for the pair.

Security cameras

This is an area where the price can vary quite significantly. Do you just want a single indoor camera pointing at the front door? Or do you want a house-wide surveillance system with night vision, infrared lighting, flood lighting and facial recognition?

The former starts at just $20 for the Alexa-controlled Wyze Cam, while pricer options (with more features) include several options from Google's Nest smart home division starting at a little under $200. Netgear-owned Arlo is also a strong option when it comes to smart security cameras.

Many security cameras require a subscription service to view the footage they record for more than a day or so afterwards. Nest, for example, charges between $6.99 and $19.99 a month, depending on how long you want to have access to recordings.

Realistically, we can see a four-bedroom home having two cameras outside and one inside pointing at the front door. For this setup you'll want to budget around $300-$600 depending on which models of camera you opt for.

Alarm system

Beyond cameras, a smart home security system should also include sensors to alert you to open windows and doors, motion sensors, and smoke detectors which buzz your smartphone.

Here, you should decide if you want to install a DIY system of off-the-shelf cameras and sensors, or hire a professional to install an alarm system with 24/7 monitoring.

Alarm specialists ADT offers the latter, and so too does Vivint. Their monitored systems are professionally installed and the costs vary depending on the size of your property and the kind of system (and monitoring) you want.

For a solution that falls between DIY and professional, Abode offers a starter kit for $299 which includes a couple of door and window sensors, an indoor motion sensor with camera, a remote key fob for arming and disarming the system as you come and go, and a smartphone app for iOS and Android. Extra sensors start at $29 and 24/7 monitoring costs $15 a week or $8 for a three-day weekend, making it perfect for occasional use.

Meanwhile, a Nest Protect smoke and carbon monoxide alarm will set you back $119, and Wyze offers its cut-price Sense kit for $20.

Garden tech

If you garden is large enough to justify it, then a smart irrigation system can help save you time and money.

Options here include the $230 Rachio 3, $200 Spruce, and the Orbit B-hyve, which starts from $79.

Most smart irrigation systems share the same key features. They connect to your existing watering system and track hyperlocal weather forecasts to deliver exactly the right amount of water each day, skipping days when there is rainfall.

The systems also ask you to tell them about the type of plants you have, as well as the soil, shade and gradient of the garden, which all adjusts how much water is used, and when. As with LED lighting and a smart thermostat, an irrigation system like this should save you money in the long term by only using water when necessary.

You could also consider a robotic lawn mower, which is basically a Roomba for the grass. The brands to consider are Worx and Husqvarna, and prices are in the region of $1,000

The best smart garden devices and outdoor gadgets

  • Total spend: circa $15,000

This brings our grand total to approximately $15,000. For this, we have kitted out a four-bedroom home with smart lights in every room, several smart speakers and plugs, an intelligent thermostat, motorized blinds on every window, an alarm system with security cameras, a smart doorbell and door locks, a pair of robotic vacuum cleaners, a smart irrigation system and a robotic lawn mower.

Of course, we could throw in a $6,000 smart fridge and a $2,000 Peloton smart exercise bike, plus other items like a smart bathroom scale, media streaming sticks on every television, and even more impressive lighting systems - not to mention a house-wide Sonos system. But we hope this has given you a flavor for what costs are involved in making an entire house smarter.
