We love being able to see all of our home automation devices in the Home app, but the best part of HomeKit is using it with Siri, Apple's voice-activated assistant. Whether it is through our iPhone, Apple Watch, or HomePod, we use Siri to turn off our lights, set the temperature, and to check on things such as humidity levels around our home.

Need a little help getting your accessories and your home set up? Check out our handy guides below.

What works with Siri and HomeKit?

You can control your HomeKit accessories on any device where you're logged in to your iCloud account: That includes the iPhone, iPad, iPod Touch, Mac, Apple Watch, Apple TV, and HomePod.

How to use Siri while outside of your home

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

What Siri commands can I give HomeKit accessories?

At its core, Siri is best used with your HomeKit accessories to turn items on and off, check temperatures and readings, and adjust them if necessary.

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

"Turn on the lights."

This all-purpose command will turn on any HomeKit-enabled lights that you have in your home.

"Turn on the lights in the Dining Room."

This will turn the lights on in a specific room you've previously set up.

"Turn off the lights Downstairs."

This will turn all the lights off in the Downstairs zone.

"Set the Living Room lights to 65."

This will dim all the lights in the Living Room (if possible) to 65 percent. (You can also use this command for a specific light name, too.)

"Set the Living Room lights' saturation to 65."

If you have color-changing lights, this will set the saturation of the lights in the Living Room (if possible) to 65 percent. (You can also use this command for a specific light name, too.)

"Set the Office lights to blue."

If you have color-changing lights, this will change their color to blue. You can substitute just about any color, and Siri will adjust as necessary if it can't find the color you're looking for. (You can also use this command for a specific light name, too.)

"What's the temperature in the Living Room?"

This checks with a thermostat or room sensor to give you the temperature of the Living Room.

"What's the humidity in the Bedroom?"

If you have one, this checks with a thermostat or room sensor to give you the humidity of the room.

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

"Close the Living Room blinds."

This will close the automated blinds in the Living Room.

"Lock the Front Door."

This will lock the automated HomeKit lock labeled Front Door.

"Are there any doors/windows open?"

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