HomeKit

See All Stories

HomeKit is Apple's home automation framework that lets you control connected accessories from your iPhone, iPad, Apple Watch, HomePod, and Siri.

Your home at your command.

What is HomeKit / Apple Home?

Along with several other new APIs for developers, Apple announced HomeKit in June 2014, which allows all home automation accessories/devices to work together in harmony with iOS. The API allows home automation developers to centralize all home automation without needing separate apps to access each device’s specific features. These devices include locks, lights, cameras, doors, thermostats, plugs, switches, and more.

HomeKit allows for secure pairing with devices and the ability to control individual devices. It also makes it possible to group several home automation devices into scenes that allow for easier control of any automation device in specific situations. One of the coolest features available with HomeKit is the ability to control any home automation accessory with Siri based on certain commands or scenes previously configured with these devices.

In 2016, Apple introduced a new Home app that came with a modern look, relatively easy-to-use controls, and access to accessories and scenes from anywhere on iOS 10. Apple’s new built-in Home app arrived on the iPhone’s Home screen, plus you can access a ton of functions from the Lock screen or anywhere on iOS from the new Control Center once you have a HomeKit accessory set up.

In 2018, Apple released the HomePod. It was a way to interact with your connected home devices through Siri using a standalone device.

In 2020, Apple announced that tvOS 14 would gain access to the Home app. iOS 14 is also bringing improvement to the Home app UI.

HomeKit Secure Video

With iOS 13, Apple announced HomeKit Secure Video.

Footage from home security cameras contains your most personal and sensitive data. With HomeKit Secure Video, activity detected by supported cameras is privately analyzed by your home hub using on‑device intelligence to determine if people, pets, or cars are present. When important activity is detected, you and anyone you share your Home app with will receive a rich notification that lets you view the clip right from the Lock Screen. Recorded video is available to view for ten days from the Home app. It’s securely stored for free in supported iCloud accounts and doesn’t count against your storage limit.

While the rollout has been slow, Logitech, Arlo, Netatmo, and Eufy are among the early standouts. With recent privacy issues with Ring, HomeKit Secure Video is likely to continue to grow in popularity. One key benefit with Secure Video is that it works with your existing iCloud storage (200GB and up plan), so you don’t have an extra monthly fee for storage.

HomeKit Router

HomeKit Router was also announced with iOS 13, but it wasn’t released until early 2020. The idea behind the feature is you can give granular control to smart home enabled devices to control where on the internet they can reach.

eero was the first company to roll out support in for HomeKit Router.

With Apple HomeKit, eero gives you even more protection of your HomeKit accessories and an easy way to manage what they are allowed to communicate with in your home and through the internet.

There are three levels of security Apple offers for accessories paired with HomeKit routers:

  • Restrict to Home: Most secure. Your accessory can interact only with HomeKit through your Apple devices. The accessory won’t connect to the Internet or any local devices, so any third-party services, like firmware updates, might be blocked.
  • Automatic: Default security. Your accessory can communicate with HomeKit and connections recommended by its manufacturer.
  • No Restriction: Least secure. This setting bypasses the secure router and allows your accessory to interact with any device in your network or Internet-based service.

How Do You Use HomeKit?

Homekit app

HomeKit devices can be controlled from iPad, iPhone, Mac, Apple Watch, and HomePod. A 4th generation Apple TV (or newer) is an essential Apple smart home device as it acts as a bridge over iCloud to allow access to your devices when away from home.

9to5Mac’s Bradley Chambers does a regular column about the “Apple Home” lifestyle in his HomeKit Weekly column.

HomeKit support for Molekule Air Purifier said to be nearing public rollout

Update: Molekule is refuting the claim made by one of its employees, saying HomeKit support is not in its immediate plans.

HomeKit support for air purifiers has been somewhat of a sore thumb for many users, with Apple’s own HomeKit website proving as a source of unreliable information. Now, however, Molekule Air Purifier HomeKit support is seemingly on the horizon.

Apple adds AirPlay 2 receivers category to HomeKit accessories list

AirPlay 2 receivers

Apple has expanded its list of HomeKit categories with a new entry: AirPlay 2 receivers. We’ve seen upcoming and currently available AirPlay 2 speakers including HomePod, Sonos, and Libratone on Apple’s HomeKit accessory list since Apple’s wireless audio streaming solution debuted earlier this year. The addition of AirPlay 2 receivers adds a new way to control audio with HomeKit, and receiver maker Denon is owning the category for now.

HomeKit Weekly: Libratone Zipp retroactively brings AirPlay 2 to a Bluetooth & Wi-Fi speaker

HomeKit Weekly

HomeKit Weekly is a series focused on smart home accessories, automation tips and tricks, and everything to do with Apple’s smart home framework. 

HomeKit speakers have an interesting place in the Home app. They’re primarily there so you can name a speaker and assign it to a room in your home. Then you can stream audio to it over AirPlay 2 and control audio playback with Siri. There’s not much more to HomeKit speakers than that yet.

Libratone Zipp is a portable Bluetooth and Wi-Fi speaker that retroactively gained AirPlay 2 support this month through a free software update. The portable speaker now has a place in the Home app with other HomeKit accessories like HomePod and newer Sonos speakers, and it plays nice with these speakers with AirPlay 2.

The combination of Bluetooth, AirPlay 2, and a built-in battery makes it a versatile option for HomePod-like audio without always being anchored to a power outlet.

HomeKit Weekly: Essential and advanced smart home accessory recommendations

HomeKit Weekly

HomeKit Weekly is a series focused on smart home accessories, automation tips and tricks, and everything to do with Apple’s smart home framework.

HomeKit Weekly started earlier this year with an overview of how the Home app works on iPhone, iPad, and Apple Watch (and Apple TV with Siri), and the Home app has since found its way to the Mac with macOS Mojave. Along the way we’ve recommended smart locks, shades, fans, garage door openers, security cameras, and more.

This week I want to use my HomeKit experience to create a smart home starter pack. If you’ve never tried HomeKit before or you want new ways to expand your smart home, these picks from each category should be useful.

HomeKit Weekly: If it doesn’t work with Siri, it’s just not a smart home

HomeKit Weekly

HomeKit Weekly is a series focused on smart home accessories, automation tips and tricks, and everything to do with Apple’s smart home framework.

This column is typically used to share recommendations and advice around using HomeKit, but this week I want to zoom out and talk specifically about why you should choose HomeKit.

There are a lot of “smart home” platforms on the market and plenty of connected accessories with iPhone apps, but I actively avoid products that don’t work with Siri. If you’re deep in the Apple product ecosystem, non-HomeKit smart home products can be a serious frustration.

Smart Home Diary: An update to our blinds revealing that Alexa is no smarter than Siri

I’ve played around a bit with Alexa, and even considered buying an Echo Dot or two before the launch of HomePod, but in the end decided to wait it out.

However, while Hunter Douglas is still promising HomeKit support for our Luxaflex Duette blinds, and was expecting to get there by now, certification has been delayed until later in the year. In the meantime, it’s gone ahead with the launch of the new bridge which brings voice control to the blinds – but so far only for Alexa and Google Home …

HomeKit devices getting more affordable as Lenovo announces Smart Home Essentials line

HomeKit offers two big advantages over generic smart home devices. First, it enables Siri control; second, Apple’s security requirements add a great deal of reassurance at a time when smart homes are beginning to make an attractive target for hackers.

But HomeKit-compatible devices do tend toward the more expensive end of the price range, a problem Lenovo has set out to tackle with its upcoming Smart Home Essentials line …

HomeKit Weekly is a series focused on smart home accessories, automation tips and tricks, and everything to do with Apple’s smart home framework.

Capturing and checking hyperlocal temperature and humidity with Siri and the Home app is one of my favorite HomeKit tricks. Weather apps that show your city’s current conditions and forecast are great, but knowing the actual temperature right outside your front door in real-time is neat. This can work with both outdoors or with specific rooms inside using the right sensors and configuration.
