The Home app is simple once the account, the update and the home hub are sorted. Here is the order that avoids the usual dead ends.

Apple HomeKit lives in the Home app on your iPhone, and the first real decision is the home hub: an Apple TV or a HomePod that stays at home and runs your automations while you are out. Since iOS 18 an iPhone can add Matter accessories on its own, but Apple still recommends a hub, and sharing the home with family or getting Home notifications on the latest Apple Home needs one. Sort the account, the update and the hub first, then add accessories room by room. For the wider picture, see smart home installation.
People search for HomeKit, Apple calls the current product Apple Home, and the thing you actually open is the Home app. They are the same system seen from three angles: a set of rules for how accessories talk to Apple devices, an app that shows them room by room, and an account that holds the home and the people allowed into it.
What makes it different from a brand app is that it does not sell you the lights or the locks. It is the control layer that sits above accessories from many makers, as long as they support Apple Home or the Matter standard. If you are still deciding between platforms rather than setting one up, the ecosystem comparison is the better place to start; this page assumes the household is on iPhones and wants the Home app to be the front door.
Most failed set-ups we are asked to rescue go wrong before the first accessory. Apple's own troubleshooting points at the same few things again and again, so clear them up front.
| Check | Why it matters | Where to look |
|---|---|---|
| One person is the home owner | Only the owner can add a HomePod or Apple TV as a home hub | Home app, More, Home Settings |
| Two-factor authentication on | Apple asks for it, together with iCloud Keychain, before updating or sharing | Settings, your name, Sign-In and Security |
| iCloud Keychain on | Matter pairing keys are stored and synced there | Settings, your name, iCloud |
| Every device on current software | Older software loses access to an updated home | Settings, General, Software Update |
| Phone on the home WiFi | The accessory joins the network the phone hands it | Settings, Wi-Fi |
Decide early whose Apple Account owns the home. In a family that is usually the person who will look after it, not whoever happens to unbox the first bulb. Moving ownership later is fiddly, and every accessory lives under that home.
Apple's support page on home hubs explains what one is for: controlling accessories while you are away, sharing control with others, and running automations on their own. A HomePod mini or HomePod becomes a home hub automatically when you set it up. An Apple TV becomes one when you add it to a room in the Home app.
| Device | Can be the home hub on the latest Apple Home? | Good to know |
|---|---|---|
| HomePod mini | Yes, automatically when set up | Named by Apple as a Thread-enabled hub |
| HomePod | Yes, automatically when set up | Apple lists HomePod (2nd generation) for Thread accessories |
| Apple TV | Yes, once added to a room | Apple TV 4K is named for Thread; check the exact model |
| iPad | No | Apple dropped iPad as a home hub on the latest Apple Home |
| Mac | No | You can view the home, but you cannot add accessories from a Mac |
Place the hub where it has steady power and a strong WiFi signal, ideally near the middle of the home. It must be at home, connected and switched on to work, which is one more reason not to treat it as a portable speaker. If you have more than one, the Home app picks an active hub on its own; you can see which one under Home Settings, Home Hubs and Bridges, and turn off automatic selection if you want to choose.
Apple notes that HomePod mini, HomePod and Apple TV are not available in every country or region. Check what is sold locally through Apple's own channels before you plan around a particular model.
Apple's Matter support page says an iPhone on iOS 18 or later can add Matter accessories to the Home app and control them without a home hub, and that iPhone 15 Pro and later models can control Thread-based accessories without one. That is useful for a renter with two smart plugs and a lamp. It stops being enough once you want automations that run while the phone is out of the house, remote control, Home notifications or a shared home, which is why Apple still recommends a hub.
Thread is a low-power mesh radio used by many newer sensors, buttons and blinds. A Thread accessory needs a Thread-enabled hub or border router to reach the rest of the home; the protocols explainer covers how Thread, Zigbee and WiFi differ.
Apple moved homes to a new version of Apple Home and says support for the previous version ended on February 10, 2026. If you are part of a home that still uses the old version, the Home app will prompt you to update, or the home may be upgraded automatically. The update runs from the Home app: More, Home Settings, Software Update, Update Now.
The catch is older hardware. Any device that does not run iOS 16.2, iPadOS 16.2, macOS 13.1, tvOS 16.2 or watchOS 9.2 or later loses access to an updated home until it is updated, and that includes the phones of people you invited. Before updating, walk round the family and check every iPhone, iPad and Apple TV.
Accessories are added from an iPhone or iPad. Apple's steps, in order:
Keep the set-up code. Photograph the label or the card that came in the box and store it somewhere safe, because a reset accessory usually needs the same code to come back. Apple Home also supports multipack pairing: if a pack includes a multi-device QR code, scanning it pairs every accessory in the pack.
If the accessory is a WiFi device and the app reports that it could not connect, the problem is often the router rather than Apple Home. The WiFi pairing guide walks through band steering and router settings.
Matter is the cross-brand standard that lets one accessory work with several apps. Apple lists the Matter accessory types the Home app currently supports: air conditioners, bridges, lights, locks, outlets, switches, thermostats, blinds and shades, and sensors for motion, ambient light, contact, temperature and humidity.
Two Apple-specific details save a lot of confusion. First, if a Matter accessory was already paired with another app, add it from the Home app by tapping More options and choosing it, rather than resetting it. Second, Matter pairing keys sync through iCloud Keychain, so every paired Matter accessory shows up under Settings, General, Matter Accessories, whichever app you used. From there you can also remove an accessory from one connected app or from all of them.
Name things the way the family speaks. A room called Master Bedroom and a light called Ceiling makes voice commands and scenes easy to guess; three lights all called Light makes them useless. Put every accessory in the room it physically sits in, and use zones for groups such as Upstairs.
Scenes and automations are where the Home app earns its place: one tap for Good Night, or lights that come on when the front door opens after dark. Automations that run while you are out need the home hub. Language support for Siri differs from Google and Alexa; the voice assistant comparison covers which assistant handles what.
Invite people from the Home app rather than sharing one login. Apple's update page notes that sharing control and receiving Home notifications on the latest Apple Home need a home hub, and that invited people also need two-factor authentication and current software. Decide who can edit and who can only control, and remove a helper or a tenant from the home when they leave.
If the house has a mix of iPhone and Android users, plan for it now. Matter helps here: Apple's page says a Matter accessory paired with one app can be added to another app that supports Matter, so the same lock or plug can also appear in the app an Android user prefers.
| What you see | What to check first |
|---|---|
| Apple TV will not join a room | You are the home owner, and you are the Default User on the Apple TV |
| Hub shows as not responding | It is at home, on the home WiFi, switched on and on current software |
| Cannot update the home | Two-factor authentication and iCloud Keychain for you and invited people |
| Matter accessory already used elsewhere | Add it via More options instead of resetting it |
| Thread accessory unreachable | A Thread-enabled hub is set up and powered |
| WiFi accessory fails at the last step | The WiFi band the device uses, and router settings |
Restarting the HomePod, Apple TV or iPad involved is on Apple's list too, and it is worth doing before anything more drastic. Reset an accessory only as a last step, and only if you still have its code.
We set up the Home app, the home hub, rooms, scenes and automations, add the accessories and pair them to the family's accounts, with the accounts kept in your name. Locks, sensors, plug-in devices and voice assistants we install ourselves. For smart switches and anything wired into the mains, we supply the devices and set up the app, and the switch or wiring work is done by an electrical contractor registered with Suruhanjaya Tenaga that we coordinate. Any mains electrical work, such as a new power point, a change at the distribution board or a hardwired switch that needs new wiring, must be done by an electrical contractor registered with Suruhanjaya Tenaga.
