Setting up a connected home used to mean juggling five different apps, half a dozen incompatible hubs, and a lot of trial and error. That’s changed. With Matter, the industry standard that lets devices from different brands talk to each other, and more capable AI built into everyday gadgets, building a smart home in 2026 is simpler and more reliable than it’s ever been.
If you’re wondering where to start, this guide breaks down the must have smart home devices worth prioritizing, why each one earns its place, and what to look for before you buy. Whether you’re starting from zero or filling gaps in an existing setup, these ten categories cover the essentials: security, comfort, energy savings, and everyday convenience.
Why These Are Considered Must-Have Smart Home Devices
Not every gadget with an app deserves a spot in your home. The devices on this list generally share three qualities: they solve a real, everyday problem; they work well with other smart home products (ideally through Matter); and they’ve built a track record of reliability rather than being a novelty. That combination is what separates genuinely must have smart home devices from things that end up unused in a drawer.
1. Smart Speakers and Voice Assistants
A smart speaker is typically the control center of a connected home. Devices like Amazon Echo, Google Nest, and Apple HomePod let you manage lighting, thermostats, locks, and cameras using voice commands instead of separate apps.
What to consider before buying:
- Amazon Alexa generally offers the widest device compatibility, which matters if you plan to mix brands.
- Google Assistant is often rated among the most accurate at understanding natural speech and follow-up questions.
- Apple HomeKit tends to appeal to privacy-conscious users, since many requests are processed on-device rather than in the cloud.
Since your choice of voice assistant often determines which other devices integrate most smoothly, it’s worth picking a platform first and building outward from there.
2. Smart Thermostats
A smart thermostat learns your household’s schedule and adjusts heating and cooling automatically, which can reduce energy waste without sacrificing comfort. Many models allow remote control from a smartphone, so you can adjust the temperature before you get home.
According to Department of Energy efficiency estimates, a properly programmed smart thermostat may save a household roughly $150 a year on utility costs, though actual savings vary based on climate, home insulation, and usage habits. Look for models with geofencing (which detects when you leave or approach home) and compatibility with your existing HVAC system before purchasing.
3. Smart Locks
Smart locks let you lock and unlock doors remotely, generate temporary access codes for guests or service providers, and receive alerts when someone enters or exits. This is one of the must have smart home devices for anyone who has ever wondered, mid-commute, whether they locked the front door.
Look for models with:
- Auto-lock and auto-unlock features
- Backup physical key access in case of power or battery failure
- Matter or platform-specific compatibility (Alexa, Google Home, Apple Home)
Many models also log entry activity, which can be useful for monitoring deliveries or checking in on family members.
4. Smart Security Cameras
Security cameras remain one of the most commonly adopted smart home categories, and for good reason: they provide real-time visibility into your property whether you’re home or away. Current models generally offer features like:
- AI-based detection that distinguishes people, pets, and vehicles from irrelevant motion like blowing leaves, which helps reduce false alerts
- 2K or higher resolution with color night vision
- Local or cloud storage options, depending on privacy preference and subscription tolerance
When combined with a smart lock and video doorbell, cameras help form a layered security setup that monitors entry points around the clock without requiring constant manual checking.
5. Video Doorbells
A video doorbell is a specific type of camera worth calling out on its own, since it addresses one of the most common home security concerns: knowing who’s at the door before you open it. Modern video doorbells typically send instant alerts to your phone, support two-way audio, and store clips for later review. Many integrate with smart locks so you can verify a visitor and unlock the door remotely in the same app.
6. Robot Vacuums and Mops
Robot vacuum-mop combos have become significantly more capable, with some models reducing manual cleaning time by a wide margin through automated scheduling, self-emptying bases, and mopping functions that activate only on hard floors. Higher-end models can navigate multi-room layouts, avoid obstacles, and return to a dock to empty debris and refill cleaning solution automatically.
Budget matters here more than in most categories: entry-level robot vacuums typically start under $200, while premium self-maintaining models can run well over $1,000. For most households, a mid-range model with strong suction and reliable mapping covers everyday needs without the premium price tag.
7. Smart Lighting
Smart bulbs, switches, and plugs let you control lighting by voice, app, or automated schedule. Beyond convenience, this category contributes to security (lights that turn on automatically when you’re away can make a home look occupied) and energy efficiency (automated shut-off prevents lights being left on unnecessarily).
Smart plugs are also worth mentioning as an entry point for anyone new to home automation: they convert non-smart devices like lamps, fans, and coffee makers into app- and voice-controlled gadgets without any rewiring.
8. Smart Smoke and Carbon Monoxide Detectors
Safety devices don’t always get the attention they deserve on smart home lists, but connected smoke and CO detectors are among the most practical must have smart home devices available. They send a phone alert if smoke or carbon monoxide is detected, even when you’re not home, and many models can test themselves periodically and notify you before batteries run low.
9. Smart Plugs and Energy Monitors
Energy monitors track electricity usage in real time, helping identify which appliances draw the most power and where savings might be possible. Combined with smart plugs, they let you schedule or remotely control individual devices, which can reduce standby power waste from electronics left plugged in unnecessarily.
10. Smart Home Hubs and Displays
As your device count grows, a central hub or smart display becomes increasingly useful for managing everything from one place. Wall-mounted displays and hub devices can show camera feeds, control climate and lighting, and run automations without needing to open multiple apps. If you’re buying new devices, prioritizing Matter-certified products here helps ensure your hub works with whichever platform you choose now, and any you switch to later.
How to Choose the Right Smart Home Devices for Your Needs
With so many must have smart home devices on the market, prioritization helps avoid decision fatigue. A reasonable approach:
- Start with your platform. Decide between Alexa, Google Home, or Apple Home based on which ecosystem you already use for phones or other devices.
- Address security first. Locks, cameras, and doorbells generally offer the most immediate, tangible benefit.
- Add comfort and efficiency next. Thermostats and lighting typically pay for themselves over time through energy savings.
- Layer in convenience last. Robot vacuums, smart plugs, and hubs round out the setup once the essentials are in place.
Buying Matter-certified devices where possible is generally a safe long-term strategy, since it reduces the risk of a product becoming incompatible if you switch ecosystems down the road.
Frequently Asked Questions
Do I need a hub for a smart home to work?
Not necessarily. Many modern devices connect directly to Wi-Fi and a smartphone app. A dedicated hub becomes more useful as your device count grows or if you’re using older Zigbee or Z-Wave products that need a bridge to communicate with Matter-based systems.
Are smart home devices secure from hacking?
Reputable manufacturers generally build in encryption and regular firmware updates, but no connected device is completely risk-free. Using strong, unique passwords, enabling two-factor authentication where available, and keeping firmware updated are practical steps that reduce risk.
What’s the most important smart home device to start with?
There’s no universal answer, but a smart speaker or display is often recommended as a starting point since it typically becomes the control hub for everything added afterward.
Final Thoughts
Building a smart home doesn’t require buying everything at once. Starting with one or two must have smart home devices, such as a smart lock or a video doorbell, and expanding gradually tends to produce better results than an all-at-once purchase, since it gives you time to settle on a platform and confirm compatibility before scaling up. Focus on devices that solve real problems in your household, prioritize Matter compatibility for future flexibility, and your smart home setup should grow smoothly as your needs change.
