7 Smart Home Devices That Are Worth It

Smart home devices have come a long way from novelty gadgets to genuinely useful tools that save time, cut energy bills, and add real security. Most devices set up in minutes, work with what you already own, and pay for themselves faster than expected.

The secret to a great smart home isn't buying everything at once — it's picking devices that match how you actually live. A smart thermostat earns its keep in a house with seasonal temperature swings. A video doorbell matters most where package theft runs high. Smart locks make sense for households constantly lending out keys.

This guide covers 7 categories that routinely prove their worth: smart speakers, thermostats, security cameras and doorbells, smart lighting, smart locks, smart plugs and energy monitors, and smart displays. Each section draws from expert-tested reviews so you can shop with confidence.

What ties these together is the Matter standard, a cross-brand protocol that lets devices from different companies work together. Launched in 2022, it has made the smart home far more flexible — and nearly every top pick in this guide supports it. The options have never been better, and prices have never been lower.

Smart Speakers & Voice Assistants

A smart speaker is usually the first device people buy — and for good reason. It's the fastest way to start controlling a smart home with voice alone, and it doubles as a hub for Alexa, Google Assistant, or Siri routines.

The Amazon Echo lineup remains the most compatible with third-party smart home gear, while Google Nest Audio wins on voice recognition accuracy and search-powered answers. Apple HomePod models are the pick for heavy iPhone and Apple HomeKit users. Sonos speakers offer the best audio quality if music matters more than smart home commands. Budget-conscious buyers should look hard at the Echo Dot or Google Nest Mini — both pack the full voice assistant experience for around $50, and both earn top spots in expert roundups from Tom's Guide and Digital Trends.

What voice assistant works with the most smart home devices?

Amazon Alexa currently supports the widest range of third-party smart home devices, making it the easiest starting point for most households building a new system.

Do smart speakers need a hub to control other smart home devices?

Many modern smart speakers with Matter support can control compatible devices directly, but older Zigbee or Z-Wave devices may still need a dedicated hub.

Can I use multiple smart speakers from different brands?

Yes, with Matter-compatible devices you can mix brands. Sticking to one ecosystem — Alexa, Google, or Apple — still offers the smoothest experience for daily routines.

Smart Thermostats

A smart thermostat is one of the highest-return smart home purchases available. The Ecobee Smart Thermostat Premium and Google Nest Learning Thermostat (4th Gen) regularly top expert charts, and for good reason — both learn your schedule, adapt automatically, and can shave meaningful dollars off a monthly energy bill. The Ecobee wins on compatibility breadth and its built-in Siri and Alexa support. Nest scores on AI scheduling smarts and a sleek new design that launched in 2024. For budget shoppers, the Ecobee Essential and Honeywell Home T9 both deliver solid scheduling and remote access at a lower price. Consumer Reports lab data confirms smart thermostats can reduce heating and cooling costs by up to 23%, which pays back most models within a year or two.

How hard is it to install a smart thermostat yourself?

Most smart thermostats install in 30 minutes or less using existing wiring, but C-wire requirements vary by model — check your HVAC system compatibility before buying.

Do smart thermostats work without Wi-Fi?

Smart thermostats operate their existing schedule when offline but lose remote access and learning features, which return once Wi-Fi is restored.

Which smart thermostat saves the most energy?

Consumer Reports and Tom's Guide both find the Ecobee Smart Thermostat Premium delivers the strongest energy savings thanks to remote sensors that prevent heating and cooling empty rooms.

Smart Security Cameras & Doorbells

The smart home security camera market moves fast, but a few names consistently outperform the rest. Arlo Pro cameras lead on video resolution, field of view, and smart detection accuracy. Ring Video Doorbells remain the most popular front-door choice with strong motion zones and tight integration with Alexa. Google Nest cameras win on face recognition and free event history. Blink outdoor cameras are the go-to when price is the priority — the company continues pushing resolution upward while keeping costs low. For doorbells specifically, Digital Trends and Bob Vila both recommend models with package detection and person-only alerts to cut down on false notifications. All top-rated models now support local storage options, reducing subscription dependency.

Do home security cameras need a monthly subscription to work?

Basic recording and alerts work without a subscription on most cameras, but advanced AI detection, extended cloud storage, and face recognition typically require a paid plan.

What is the best outdoor security camera for renters?

Wireless battery-powered cameras from Blink, Arlo, or Ring are ideal for renters since they require no permanent wiring and can move with you when you leave.

How many security cameras does a typical home need?

Most security experts recommend covering the front door, back door, and garage — a 3-camera setup covers the entry points where most incidents occur.

Smart Lighting

Smart lighting is one of the easiest upgrades in any home — screw in a bulb, download an app, and you're done. Philips Hue remains the gold standard for color accuracy and ecosystem depth, with hundreds of compatible fixtures and the most mature app on the market. WiZ bulbs offer solid Matter support at a much lower price and are TechRadar's pick for first-time buyers. Govee and Nanoleaf stand out for decorative strips and panels that add ambient lighting to gaming setups, home offices, and living rooms. All top picks support scheduling, away mode, and integration with security cameras for motion-triggered lighting — one of the most practical smart home automations available. Energy savings are real but modest compared to a smart thermostat, typically in the 10–15% range per bulb replaced.

What is the difference between smart bulbs and smart switches?

Smart bulbs give you color and dimming control per socket, while smart switches convert existing fixtures and work with any standard bulb — switches are better for light fixtures you can't easily reach.

Do smart lights work during a power outage?

No — smart bulbs and switches need power to function. During an outage, they behave like standard off lights.

Can smart lights be programmed to turn on at sunset automatically?

Yes, most smart lighting apps support geo-based sunset and sunrise scheduling that adjusts automatically throughout the year.

Smart Locks & Access Control

Smart locks solve a problem most households deal with constantly: keys. The Yale Assure Lock 2 earns top marks from CNET and Bob Vila alike for its slim design, Apple Home Key support, and reliable app. Schlage Encode Plus follows closely, favored for its ANSI Grade 1 security rating and durable build. For renters or anyone who can't replace a deadbolt, August Wi-Fi Smart Lock retrofits over an existing deadbolt and keeps the exterior hardware unchanged. The Lockly Visage adds fingerprint unlocking for keypad-free entry. Every top pick supports timed guest codes — handy for housecleaners, dog walkers, or visiting family — and access logs that show exactly who came and went. Most models now integrate directly with Ring doorbells or Google Nest cameras for a unified front-door security setup.

Can a smart lock be hacked?

Smart locks use encrypted Bluetooth and Wi-Fi connections, but like any connected device, firmware updates are critical — keep them current and use strong unique passwords for linked accounts.

What happens if a smart lock battery dies?

Most smart locks use AA batteries with months of life and send low-battery alerts well in advance. Many also include a physical key slot or 9V battery jump as a backup entry method.

Do smart locks work with apartment intercom systems?

Some smart locks integrate with intercom and building access systems, but compatibility varies — check with your building management before purchasing.

Smart Plugs & Energy Monitors

Smart plugs are the cheapest way to add automation to any home. Plug one into a standard wall outlet, connect a lamp or coffee maker, and you have remote on-off control, scheduling, and — on better models — energy monitoring. The TP-Link Kasa EP25 and Emporia Smart Plug consistently top expert roundups from TechRadar and Digital Trends for their compact size, reliable apps, and accurate energy tracking. For the full picture of home electricity use, a whole-home energy monitor like the Sense Home Energy Monitor clips onto your electrical panel and shows real-time appliance-level usage — Bob Vila recommends it for households actively trying to trim utility bills. Matter-compatible plugs are now widely available and work cleanly across Alexa, Google, and Apple HomeKit without a separate hub.

What can a smart plug actually automate?

Smart plugs work best with simple on-off devices: lamps, fans, coffee makers, space heaters, and holiday lights. They cannot control devices with digital controls that need to be manually powered on.

Do smart plugs save energy?

Smart plugs eliminate standby power draw by cutting power completely on a schedule, and energy-monitoring models help identify appliances running longer or harder than needed.

What is the best smart plug for Apple HomeKit?

The Eve Energy smart plug is the top HomeKit pick across most expert reviews, offering Thread and Matter connectivity along with accurate energy tracking through the native Apple Home app.

Smart Displays & Home Hubs

A smart display is the closest thing to a command center for a connected home. The Amazon Echo Show 8 earns the best price-to-performance rating in its class — it streams live camera feeds, manages smart home devices by touch or voice, and handles video calls without breaking the budget.

Google Nest Hub Max wins for households deep in the Google ecosystem, thanks to Gemini AI integration and seamless Nest camera viewing. For Apple users, a mounted iPad running the Home app is the current recommendation since Apple has not released a dedicated smart display. Smart home hubs like the Aeotec SmartThings Hub go beyond displays to connect Z-Wave and Zigbee devices that Wi-Fi-only setups cannot reach — essential for complex multi-device installations. Tom's Guide's hub roundup confirms that for most households with fewer than a dozen devices, a capable smart display does the job without an additional dedicated hub.

Do I need a smart home hub if I already have an Echo or Nest device?

For Matter and Wi-Fi devices, no — Echo and Nest speakers handle hub duties natively. For Z-Wave or Zigbee devices, a dedicated hub like the Aeotec SmartThings Hub is still necessary.

Can a smart display replace a tablet for smart home control?

For dedicated in-home smart home management, yes — smart displays are optimized for voice and touch smart home control in a way that general tablets are not.

What is the best smart display for video calls?

The Amazon Echo Show 10 with its motorized rotating camera wins on video call experience, automatically tracking you as you move around the room during calls.
