How to Use Siri to Control Your HomeKit Devices

Apple's HomeKit is integrated with Siri, which means you can use the personal assistant to control HomeKit-compatible accessories like lights, thermostats, and power outlets, even when you're away from home. Here's everything you need to know to get things up and running.

Devices That Support "Hey Siri"

First, in order to use Siri to control your HomeKit accessories handsfree, you'll need an Apple device connected to a Wi-Fi or cellular network that supports the "Hey Siri" command without being plugged into a power source. Compatible devices include the following:
Note that earlier iPhone, iPad, and iPod touch models with iOS 8 or later should also support "Hey Siri," but only when plugged into a power source.

Set Up Your HomeKit Devices

Before you can start using Siri to control your HomeKit-compatible smart devices, you'll need to add them as accessories in the Home app. That's because Siri identifies your accessories by their names, location, and other details that you've added to them in the Home app.
