Best Smart Home Devices to Start With (No Hub Required)
What Works Without a Central Hub, How to Choose Your First Device, and How to Build From There
Introduction
The idea that a smart home requires a central hub, complex installation, or a large upfront investment still stops many people from getting started. That perception made more sense a few years ago, when most smart devices did rely on a hub to communicate with each other and with the user's phone.
Today, the majority of the most useful smart home devices connect directly to a home's Wi-Fi network and are controlled through a simple app, with no hub involved.
For a broader framework on how to evaluate whether any smart home device is worth buying before committing, How to Choose Smart Home Devices That Are Actually Worth It covers the practical decision process.
The idea that a hub is always required is one of the most common misconceptions about smart home technology. Common Myths About Smart Homes (Debunked) addresses this and nine other myths directly.
This shift has made starting a smart home setup significantly more accessible. A single device can be installed, tested, and evaluated before any additional commitment. If it delivers value, the setup can grow gradually. If it does not, nothing is locked in.
This article covers the devices that work best without a hub, what to look for before buying any of them, and how to choose the right first device based on what the home actually needs.
For a grounded look at what actually changes in daily life after adding smart devices, Smart Home vs Traditional Home: What Really Changes in Daily Life? provides useful context before going deeper into any specific device.
1. Why "No Hub Required" Matters for Beginners
A hub is a central device that connects and coordinates multiple smart home devices, often across different communication protocols like Zigbee or Z-Wave. It adds a layer of integration and control that becomes valuable in larger, more complex setups.
For someone starting out, a hub is an additional cost, an additional configuration step, and a commitment to a specific ecosystem before knowing which devices will actually be useful. It also adds a dependency: if the hub goes offline, connected devices may stop responding.
Devices that connect directly over Wi-Fi remove that layer entirely. Each device connects independently to the home network, is controlled through its own app or a compatible voice assistant, and functions without any other device being present. This makes starting and stopping easy, and keeps the initial investment proportionate to actual use.
The trade-off is that managing several devices from different manufacturers eventually means managing several apps. That is where a hub becomes relevant. But for a setup of three to five devices, the independence of Wi-Fi direct connection is an advantage, not a limitation.

2. What to Look for Before Buying Any Smart Device
Regardless of device type, a few practical criteria apply to every purchase decision.
2.1 Wi-Fi Frequency Compatibility
Most smart home devices operate on the 2.4 GHz Wi-Fi band, not the 5 GHz band. This is worth confirming before purchasing, because many modern routers broadcast both frequencies and some devices will only connect to one of them.
During setup, if a device fails to connect, the most common reason is that the phone is connected to the 5 GHz network while the device requires 2.4 GHz. Checking the router settings and temporarily connecting to the correct band during setup resolves this in most cases.
2.2 App and Platform Requirements
Most smart devices require a manufacturer app and an account to function. Before buying, it is worth confirming that the app is available for the phone's operating system, that it is free to use without a subscription, and that the manufacturer has a reasonable history of maintaining their products and software over time.
A device whose app has not been updated in two years, or whose manufacturer is no longer actively supporting the product line, carries a higher risk of losing functionality when the phone's operating system updates.
2.3 Voice Assistant Compatibility
Most Wi-Fi direct smart devices are compatible with Amazon Alexa or Google Home, and many support both. Confirming compatibility before purchasing allows the device to be controlled by voice without requiring a separate hub to serve as the translator.
This is particularly relevant for households that already use a smart speaker, since the speaker can then control newly added devices without any additional configuration beyond linking the accounts.
2.4 Setup Complexity in Practice
Device listings frequently describe setup as simple or plug-and-play. In most cases that is accurate, but the actual process is worth understanding: downloading the app, creating an account if required, connecting the device to the Wi-Fi network, and completing any initial configuration such as setting a schedule or naming the device.
For most Wi-Fi direct devices, this takes between five and fifteen minutes. If a device's reviews consistently mention difficult setup or frequent disconnection issues, that is a signal worth taking seriously before purchasing.
3. The Best Devices to Start With (No Hub Required)
3.1 Smart Plugs
Smart plugs are the most universally applicable starting point. They plug into any standard outlet, work with any device connected to them, require no modification to the home, and are completely reversible. Setup takes a few minutes and the plug is immediately functional.
In practical terms, a smart plug adds scheduling, remote on/off control, and in many models real-time energy monitoring to any device connected to it. The same plug can be used with a lamp today, moved to a coffee maker next month, and taken to a different home when moving.
For a detailed look at how smart plugs reduce energy waste and which situations benefit most from them, How Smart Plugs Reduce Energy Waste in Everyday Homes covers the practical application thoroughly.
3.2 Smart Bulbs
Smart bulbs replace standard light bulbs in any existing fixture without touching the wall switch or any wiring. Once installed, they connect to Wi-Fi and can be controlled through an app, scheduled to turn on and off at set times, and in many models dimmed or adjusted for color temperature.
The main consideration is the wall switch: turning the switch off cuts power to the bulb and disables app control until the switch is turned back on. For rooms where the switch is used regularly by multiple people, a smart switch may be a more practical choice. For lamps and fixtures with less variable switch use, smart bulbs work well independently.

3.3 Smart Speakers and Voice Assistants
Smart speakers are portable, require no installation beyond plugging into an outlet, and serve as an informal control layer for other compatible smart devices. Once linked to the accounts of other smart devices in the home, a smart speaker can control lights, plugs, and thermostats by voice without requiring a hub to coordinate them.
This makes the smart speaker a useful addition even when only one or two other smart devices are in place. As the setup grows, the speaker grows with it, requiring only account linking rather than hardware reconfiguration.
3.4 Smart Thermostats
Most smart thermostats connect directly to Wi-Fi without requiring a hub. They represent the highest-impact efficiency upgrade available as a single device, since heating and cooling account for the largest share of energy consumption in most homes.
The main pre-purchase step is confirming compatibility with the existing HVAC system and checking whether a C-wire is present in the wall. Both can be verified by removing the existing thermostat faceplate and checking the wiring, without any tools.

3.5 Smart Motion Sensors
Battery-powered wireless motion sensors require no wiring, no permanent mounting, and no hub in many configurations. They can be placed on shelves, inside drawers, or attached with removable adhesive strips, and removed without leaving any trace.
In practice, motion sensors trigger actions in other connected devices: turning on a smart bulb when someone enters a room, sending a notification when movement is detected in an area that should be empty, or activating a smart plug connected to a fan or lamp.
They work best as part of a small connected setup rather than in complete isolation, though some models send standalone app notifications without requiring other devices.

3.6 Smart Switches
Smart switches replace the existing wall switch and control all the lights on that circuit. Unlike smart bulbs, they do not require replacing individual bulbs and work with any bulb type already installed. This makes them more cost-effective in rooms with multiple light points on the same circuit.
Installation requires access to the wiring behind the switch plate and the presence of a neutral wire in most models. This is a step beyond plug-and-play, but does not require professional installation in most cases. The result is a room-level smart lighting solution that is not affected by how or when the switch is physically used.
4. How to Choose Your First Device
The right starting point depends on what the household most wants to improve. A device chosen for a specific, immediate purpose delivers visible value and builds confidence for the next step.
4.1 If the Priority Is Energy Efficiency
Start with a smart thermostat if the home has central heating or cooling and currently uses a manual thermostat with no scheduling. This single upgrade delivers the most consistent energy reduction per device of any option on this list.
If the thermostat is already programmable or recently upgraded, smart plugs on the devices with the highest consumption or the most frequent standby use are the next most impactful starting point.
4.2 If the Priority Is Daily Convenience
Start with smart bulbs in the room used most often, or a smart speaker as a central control point for devices that will be added gradually. Both deliver immediate, tangible convenience without requiring any assessment of energy consumption patterns.
4.3 If the Priority Is Security and Peace of Mind
Start with smart plugs on the devices most often associated with the "did I leave that on?" concern, such as irons, space heaters, or straighteners. Add a motion sensor for awareness in key areas, such as an entry point or a room that should be empty during certain hours.
4.4 If You Rent
Focus entirely on portable devices: smart plugs, smart bulbs, and smart speakers. All three leave no trace when removed and move with the household at the end of any lease.

5. When Does a Hub Actually Make Sense?
A hub becomes useful when the number of connected devices grows large enough that managing each through a separate app becomes inconvenient, or when devices from different manufacturers need to work together in automations that a single app cannot coordinate.
For most setups of three to five devices, all from compatible manufacturers, the independent Wi-Fi connection model works well and adds no unnecessary complexity. The hub question is worth revisiting after a setup has been running for several months and the household has a clear sense of which devices are being used consistently and how they might work better together.
Starting without a hub does not foreclose adding one later. Most major hub platforms are designed to absorb existing Wi-Fi devices alongside new ones, making the transition gradual rather than requiring a full replacement.

Final Thoughts
Starting a smart home without a hub is not a compromise. For most households beginning with one or two devices, it is the most practical approach: lower initial cost, no ecosystem commitment, and the flexibility to evaluate each device on its own merits before expanding.
The devices covered in this article, smart plugs, smart bulbs, smart speakers, thermostats, motion sensors, and smart switches, cover the full range of daily use cases that matter most in a residential setup. Each works independently, and each can be integrated into a larger system later if and when that becomes useful.
The best first device is the one that solves a specific, real problem in the household today. Everything else can follow from there.
