We like to see all our home automation devices in the Home app, but the best part of HomeKit is its use with Siri, Apple's voice-activated assistant. Whether it's iPhone, Apple Watch or HomePod, we use Siri to turn off our lights, set the temperature and check things like the humidity level around our home.

What works with Siri and HomeKit?

You can control HomeKit accessories from any device where you are logged into your iCloud account: It includes iPhone, iPad, iPod Touch, Mac, Apple Watch, Apple TV and HomePod.

How to use Siri outside your home

If you have a HomeKit hub, you can issue Siri commands outside your local Wi-Fi network and still access HomeKit devices. HomeKit centers include Apple TV 3rd generation or newer, HomePod or iPad. Here's how it works.

What Siri orders can HomeKit accessories offer?

At its core, Siri is best used with HomeKit accessories to enable and disable items, check temperatures and readings, and adjust them if necessary.

Here are some of the most common phrases you can use with HomeKit and Siri:

This universal command will activate any HomeKit-enabled lights you have in your home.

This will light up the lights in a specific room that you have previously configured.

This will turn off all the lights in the lower area.

This will reduce all lights in the living room (if possible) to 65%. (You can also use this command for a specific light name.)

If you have lights that change color, this will set the saturation of the lights in the living room (if possible) to 65%. (You can also use this command for a specific light name.)

If you have lights that change color, it will change its color to blue. You can replace almost any color and Siri will adjust if necessary if she can't find the color you are looking for. (You can also use this command for a specific light name.)

This is checked with a room thermostat or sensor to give you the room temperature.

If you have one, this is checked with a thermostat or room sensor to give you room humidity.

This will set the temperature to 71 degrees for the thermostat in the living room. You can also say, "Set the Living Room thermostat to ..." for the same result.

This will turn on a HomeKit enabled TV in the living room.

This will close the automatic blinds in the living room.

This will lock the automatic front door with HomeKit lock.

Siri will return the status of a blockage, either blocked or unlocked. You can also ask yourself if there is an unlocked door in the house, and the answer will include the number of locks that are unlocked.

Siri will respond with the status of a contact sensor that is designated the kitchen door or window.

Siri will check the status of any contact sensors you have designated as doors or windows in your home.

This will disable each device located in your specified application. For example, asking Siri to stop the house will stop every device in your house.

This command will activate the specified scene and all actions that are part of it. You can also say just the name of the scene and Siri will work her magic.

This will start an air purifier that is connected to a smart connector.

This will set the speed of a HomeKit ceiling fan to 50%. HomeKit fans are adjustable in 25% steps. This command also works for HomeKit ceiling fan switches.

This will activate any HomeKit-enabled sprinkler / irrigation controller for the default runtime set in the Home application.

If a motion sensor is configured, Siri will report if motion is detected in the basement. You can also ask yourself if there is any movement in the house, and Siri will respond accordingly.

Siri will respond with the status of any HomeKit smoke detectors in your home. This also works with CO detectors.

This will set any HomeKit humidifiers or speakers to the desired humidity level.

Siri will respond with the air quality in the specified room.

This will close a HomeKit garage door opener. You can also specify a name for a specific "garage door."

Siri will respond with the status of a connected garage door opener.

Siri will respond with a live view of the rear porch room. This command only works on iOS devices.

If you have a HomeKit light sensor, Siri will respond with the current light level as a percentage.
