Everything You Need to Know About HomeKit
The HomeKit ecosystem may seem daunting and confusing if you’re unfamiliar with smart home products, their functionality, and their benefits, but getting started is actually simple and straightforward.
Learning the ins and outs of HomeKit after setup does take a bit of effort, but it’s not a difficult process and having interlinked electronics that can interact with each other and be automated can save time and really streamline your life.
What is HomeKit?
HomeKit is Apple’s smart home platform, which is designed to let you control various internet-connected home devices — ranging from thermostats and plugs to window blinds, light bulbs, and more — with Apple devices.
These days, more and more products are internet connected, which is why you’ve heard the phrase “Internet of Things.”
The Internet of Things is a confusing mix of “smart” products that connect to the internet and can be controlled by a range of different platforms, from Amazon’s Alexa to Google Home to Samsung SmartThings.
HomeKit is Apple’s “Internet of Things” solution that connects HomeKit-enabled smart accessories together in a way that lets you operate them using your Apple products.
What You Can Do With HomeKit
HomeKit isn’t a product or software, it’s a framework that links smart home products together and adds new capabilities to devices like lights, locks, cameras, thermostats, plugs, and more.
While controlling smart home products with Siri or with an iPhone is convenient, the real magic of HomeKit comes when you have multiple HomeKit-enabled products because you can control them all at once using scenes or set up automations so that they activate automatically.
You can, for example, create a “Good night” scene that makes sure the doors are locked, closes the garage, turns off the lights, lowers the thermostat, and then activates a night light whenever motion is detected. With automation, you can set individual HomeKit devices to come on or off at specific times, or you can set entire scenes, like the aforementioned “Good night” scene to come on at a set time.
HomeKit setups, scenes, and automations can be as complex or as simple as you like, and now that HomeKit is in its fifth year of availability, there are all kinds of HomeKit products you can purchase. With a bit of time and some money, you can have a whole smart home ecosystem that’s streamlined, automated, and easy to control.
Setting It Up
From there, open up the “Home” app, which comes pre-installed on all iOS devices. Tap on the “Add Accessory” button that’s on the main screen of the Home app, and then follow the steps after it opens up to the rear camera.
All HomeKit products come with a HomeKit QR code on them, which you need to scan with the camera. Scanning the HomeKit code adds a device to the HomeKit framework, and then you can follow a few additional steps to assign it to a room, a necessary step for organizing your HomeKit devices.
Types of HomeKit Devices
There are all kinds of HomeKit devices on the market, some that are more capable than others. The following HomeKit categories are available:
- Window Blinds
- Air Conditioners
- Air Purifiers
- Garage Doors
Apple maintains a full list of HomeKit-compatible devices on its website, complete with links, so this is the best place to get an overview of all of the different HomeKit devices that you can put in your home.
Smart home devices that are compatible with HomeKit will have “Works with Apple Homekit” labeling on the packaging to make it clear that they support HomeKit.

HomePod and AirPlay 2
Using HomeKit requires an iPhone, iPad, or iPod touch running the latest version of iOS, along with at least one HomeKit-enabled device.
Using the Home app on the Mac requires macOS Mojave, and to control devices when away from home, an Apple TV, iPad, or HomePod is required to serve as a Home Hub.
Ways to Control Your HomeKit Devices
The great thing about HomeKit is the myriad ways that you can control your HomeKit compatible devices.
You can use Siri voice commands on the iPhone, iPad, iPod touch, Mac, Apple Watch, HomePod, or Apple TV to ask Siri to complete HomeKit tasks.
Devices can be controlled manually in the Home app, or in the app that comes with the device. Each HomeKit device will have an app downloadable from the iOS App Store that offers a way to control it.
You can also purchase HomeKit-enabled button-type devices that serve as remotes to activate HomeKit scenes physically, and there are switches for controlling HomeKit products such as lights.

Security and Privacy
Security and privacy are topics that Apple takes seriously, and thus every manufacturer that creates a HomeKit-compatible device has to follow Apple’s security guidelines, better ensuring your devices are safe from hackers.
Apple’s commitment to privacy and demand that HomeKit products be secure is reassuring at a time when our homes are filled with smart devices that can hear us and see us.
For a long time, Apple required all HomeKit products to include a hardware-based HomeKit authentication coprocessor for HomeKit certification, and many HomeKit devices continue to offer this. In 2017, Apple began allowing manufacturers to obtain HomeKit certification with software-based authentication, but HomeKit is no less secure as a result.
All HomeKit devices use the same security features, including end-to-end encryption, non-reusable encryption keys, and two-way authentication (Apple verifies your HomeKit device and your HomeKit device verifies your Apple device) when connecting to a HomeKit setup.
A HomeKit camera, for example, sends video and audio streams directly to an iOS device and those streams are encrypted using randomly generated keys to prevent someone from intercepting your video feed.
All HomeKit data stored on your devices is fully encrypted, and HomeKit syncing between devices is done via iCloud and iCloud Keychain, both of which have their own security. Apple also must approve each and every device that gets the HomeKit labeling. In a nutshell, Apple has worked to make HomeKit a secure smart home platform that people can trust.
HomeKit is not without its bugs, though, and there have been some security snafus. In December 2017, there was a bug that left HomeKit accessories vulnerable to unauthorized access, but Apple was quick to fix it.
For those interested, the nitty gritty details about HomeKit security are available in Apple’s iOS Security Guide and are well worth checking out if you have security concerns about using smart home devices. [PDF]
Solving HomeKit Connectivity Problems
When using HomeKit devices, you might sometimes see an error that a device is unreachable in the Home app or have other problems connecting to a HomeKit product.
The Home app, and most HomeKit apps that accompany HomeKit products, provide very little info on why a HomeKit product isn’t working properly or connecting to your network, which can make troubleshooting HomeKit issues frustrating.
There are a few basic steps you can follow that will sometimes solve connectivity issues.
- Make sure the HomeKit device has power, is turned on, and is in range of your router if it’s a Wi-Fi device.
- Turn the HomeKit device off, wait a good 10 seconds, and turn it back off. Do the same thing with your iPhone or other device you’re attempting to use with HomeKit.
- Check the Wi-Fi connection and reset your router. Make sure your iOS device is up to date, connected to the internet, and that you’re signed into iCloud.
- Make sure your HomeKit device is on the right Wi-Fi band. There are a lot of HomeKit devices that are 2.4GHz while most devices connect to 5GHz networks, and that can sometimes cause problems. If you have a 2.4GHz accessory, make sure it’s on the 2.4GHz network. Steps for this will vary based on your setup.
- Remove the device from HomeKit in the Home app and then re-add it by scanning it. For some HomeKit products, this is probably a last resort step because it eliminates scenes and automations.
- Remove the device from HomeKit and reset it. This is a step that’s necessary when removing some HomeKit devices from a HomeKit setup. You’re going to need to consult the manual of your device because resetting is different on every product.
If none of these steps work, you’re going to want to contact the support staff for whichever product you’re having problems with to get further information on what to do for troubleshooting purposes.
Many HomeKit manufacturers have online troubleshooting databases, so in some cases, you can just Google for a solution.
There are more drastic steps to take, such as logging in and out of iCloud or resetting your entire HomeKit setup, but we recommend contacting a manufacturer before trying these last resort options just because of the hassle involved.
