Build Your First Apple HomeKit Smart Home from Scratch

Apple HomeKit (now officially called Apple Home) is Apple’s smart home platform, and getting started with it in 2026 requires exactly three things: an iPhone or iPad running iOS 26 or iPadOS 26, a home hub like HomePod mini or Apple TV 4K, and one compatible smart accessory. Once those pieces are connected, you control everything from the Home app using rooms, scenes, and automations that run locally on your hub without depending on a third-party cloud.

Key Takeaways

• A home hub (HomePod mini, HomePod, or Apple TV 4K) is mandatory for remote access, automations, and Matter device pairing
• iPad is no longer supported as a home hub under the current Apple Home architecture
• Matter and Thread are the current standards for new accessories, replacing older Bluetooth-only HomeKit devices
• Open Settings on your hub device and verify you see “This home and all accessories are up to date” before adding new gear
• Start with one smart plug or sensor to learn rooms, scenes, and automations before expanding your setup

At-A-Glance: Which Hub Should You Pick?

This table compares what you need to get started with Apple HomeKit, so you can decide which hub fits your home before buying a single accessory.

What Apple Home Actually Does

Apple Home is the framework that ties your smart accessories together. Lights, plugs, sensors, locks, thermostats, cameras, and robot vacuums all show up in the Home app on your iPhone, iPad, Mac, and Apple Watch. You organize devices into rooms (Kitchen, Bedroom, Office), group actions into scenes (“Good Morning” turns on the coffee maker and opens the blinds), and set automations that trigger without you lifting a finger (motion detected in the hallway at night turns on the light at 20% brightness for 90 seconds).

The real backbone is your home hub. It runs automations when your iPhone is asleep or away from Wi-Fi, handles remote access so you can check your front door camera from the office, and acts as a Thread border router for newer accessories. Without a hub, Apple Home is limited to manual, in-room Bluetooth control. With one, your entire home becomes responsive around the clock.

Why Matter and Thread Changed Everything

Before 2023, buying a smart home device meant checking a specific “Works with Apple HomeKit” badge on the box. That limited your choices. Matter, the cross-platform standard developed jointly by Apple, Google, Amazon, and Samsung, blew that gate wide open. A Matter-compatible device works with Apple Home, Google Home, Alexa, and SmartThings. When you see a Matter logo on the packaging, you know it connects to your Home app.

Thread is the networking layer underneath. Think of Matter as the language devices speak and Thread as the road they travel on. Thread creates a low-power mesh network: every mains-powered Thread device (like a smart plug) acts as a router node, relaying signals to battery-powered devices (like a motion sensor) further away. The more Thread devices you add, the stronger and more responsive your mesh becomes. Your HomePod mini or Apple TV 4K (3rd generation, 128 GB model with Ethernet) serves as the Thread border router that connects this mesh to your Wi-Fi network and the internet.

How I’d Pick a Hub for a Brand-New Setup

All three current hub options (HomePod mini, HomePod 2nd generation, and Apple TV 4K 3rd generation) support Matter and Thread. The practical differences come down to where you want the hub and what else you want it to do.

HomePod mini is the easiest entry point. Plug it into any room with a power outlet, and it becomes a hub automatically. Siri responds to voice commands, it plays music, and it extends your Thread mesh. The form factor is compact enough to sit on a nightstand or tuck behind a kitchen appliance. One physical quirk: the braided power cable is permanently attached, so you cannot swap it for a longer run without an extension cord.

Apple TV 4K (3rd generation, 128 GB) is the strongest option if your living room doubles as the center of your smart home. Ethernet connectivity gives it the most reliable hub performance, especially in homes with many Thread accessories. It becomes a hub the moment you assign it to a room in the Home app. Note that only the 128 GB model with Ethernet includes full Thread border router support. The 64 GB Wi-Fi-only model lacks an Ethernet port and has a reduced Thread capability.

HomePod (2nd generation) splits the difference: bigger speaker, room-sensing spatial audio, and full Thread support. Choose it when the hub will live in a room where music quality matters.

Apple’s support document on setting up a home hub walks through the setup steps for each device. The process takes about two minutes regardless of which hub you choose.

Setting Up Your First Room, Your First Device

Open the Home app on your iPhone. Tap the plus icon in the top-right corner, then tap Add Accessory. Point your camera at the setup code printed on the accessory or its packaging (an eight-digit code or a QR code). Apple Home pairs the device, assigns it to a room you select, and you’re done. The entire add-accessory flow rarely takes longer than 60 seconds for a Thread or Matter device when a hub is already on the network.

Assign logical room names that match how you actually talk. “Bedroom” is better than “Master Suite,” because when you say “Hey Siri, turn off the Bedroom light,” the simpler name avoids confusion. You can rename rooms later without breaking any automations.

Your First Smart Accessory: Start with a Plug

The single best way to learn Apple Home is to start with a smart plug. Plug it into any wall outlet, connect a floor lamp or a fan, and suddenly that dumb appliance responds to Siri commands, schedules, and automations. It sounds basic, but this one device teaches you every core concept: rooms, device states, scenes, and automations.

The Eve Energy (Matter) is the plug that fits this workflow perfectly. It connects over Thread, which means it pairs through your hub in seconds and doubles as a router node that strengthens your mesh network for future devices. It tracks energy consumption directly in the Eve app, so you can see exactly how many watts your connected lamp or appliance draws. There’s no Eve cloud, no account registration, no data leaving your home. The built-in physical button on the front (a small green LED that clicks) means anyone can toggle the plug without a phone. One small friction point: the body is slightly wider than a standard wall wart, so on a two-outlet plate, it will partially block the second socket. A short extension cord solves that instantly.

Adding Automation That Runs by Itself

Once your first plug is working, open the Automation tab in the Home app. Tap the plus icon and choose “When a Sensor Detects Something” or “When People Arrive” or “At a Time of Day.” For a floor lamp connected to your Eve Energy plug, try this: set an automation that turns the plug on at sunset and off at 11:00 PM every day. The automation runs on your hub, so it fires even when your iPhone is powered off or away from home.

The next logical step is a motion sensor. It unlocks the automation that makes a smart home feel genuinely smart: walk into a room, the light turns on; leave the room, the light turns off. The Eve Motion (Matter) uses the same Thread mesh as the Eve Energy plug, which means it communicates directly through your existing network without adding a separate bridge or app. Its 120-degree field of view covers up to 9 meters (about 30 feet), and IPX3 water resistance means you can mount it in a covered outdoor area like a porch. The companion Eve app on iPhone lets you fine-tune sensitivity and set a twilight threshold so the motion automation only triggers when ambient light drops below a certain level. Battery life is rated at roughly one year on a single replaceable CR2450 cell, and independent testing consistently reports 10 to 14 months depending on trigger frequency.

Scenes: Grouping Actions into One Command

A scene is a saved snapshot of multiple device states. “Good Night” might turn off the living room plug, set the bedroom plug to off, and lock the front door. “Movie Time” might dim the lights to 10% and turn on the Apple TV. You create scenes in the Home app by tapping the plus icon, selecting Add Scene, and choosing which accessories participate. Each accessory’s state is set individually within the scene editor. Once saved, you trigger the scene by tapping its tile, asking Siri, or linking it to an automation.

Name your scenes the way you’d naturally say them out loud. “Good Night” works because “Hey Siri, Good Night” rolls off the tongue. “Evening Shutdown Sequence” does not. Siri parses scene names literally, so shorter and more conversational is always better.

For readers already running a hub, our guide on protecting your Apple smart home with HomeKit water leak sensors covers one of the most practical (and overlooked) accessories you can add to your setup. And if you haven’t confirmed your home is running the latest architecture, check our walkthrough on upgrading to the new Apple Home architecture before February 10, because older setups will lose Home app access after that date.

The February 10, 2026 Architecture Deadline Matters

Apple introduced a redesigned Home architecture in late 2022 that delegates more processing to your hub instead of your iPhone. This makes automations faster, device status updates more reliable, and Matter support possible. Until now, the old and new architectures have coexisted. On February 10, 2026, Apple is pulling the plug on the legacy version. Any home that hasn’t migrated will lose access to the Home app entirely: no accessory control, no automations, no Siri commands.

Starting fresh today means you’re automatically on the new architecture. But if you’re inheriting a home setup from a family member or setting up a used HomePod, verify the architecture status by opening the Home app, tapping the More button (the three dots), selecting Home Settings, then Software Update. You should see “This home and all accessories are up to date.” Apple’s update support page details every step for homes that still need to migrate.

Where to Go After Your First Two Devices

The Thread mesh rewards gradual expansion. Each mains-powered Thread device you add (a smart plug, a light switch, a smart outlet strip) strengthens the network for battery-powered sensors and locks at the far edges of your home. A good second-week addition is a door or window sensor on your front door, which enables automations like “turn on the hallway light when the front door opens after sunset.” A third-week addition might be a smart light bulb in the bedroom that dims to 5% warm white through a “Good Night” scene.

Accessibility and Clarity

Apple Home works with VoiceOver on iPhone, iPad, and Mac. Every accessory tile in the Home app is labeled with its name, room, and current state, so screen reader users can identify and control devices without visual cues. When adding an accessory, the setup code can be entered manually instead of scanned visually, making the onboarding process fully accessible to users with low vision.

For users with motor limitations, Siri voice commands eliminate the need to reach for a phone or physically toggle a switch. “Hey Siri, turn off everything” is a single spoken command that can replace multiple physical actions across rooms. The Eve Energy plug’s built-in physical button is large enough to press with a closed fist or an elbow, which helps users who lack fine motor dexterity. The Home app’s layout is straightforward: a flat list of rooms with large tap targets. There are no nested menus or distracting pop-ups that increase cognitive load for readers with ADHD or dyslexia. Apple’s decision to keep the interface tile-based rather than list-based means fewer text-heavy screens to parse.
