How Smart Home Skills Work

Smart home skills enable customers to control your cloud-connected devices and appliances—like lights, thermostats, cameras, and coffee makers—using Alexa. With smart home skills, the voice interaction model is already built and handled for you, so you simply decide how you want customers to use your device by adding capabilities in your skill to enable those interactions.

Ways to Build for Smart Home with Alexa

The first step to building an Alexa smart home experience is to decide how your device will use Alexa. You can build voice-forward products either by integrating Alexa into your devices or by controlling your devices with Alexa. Once you've selected how your device will work with Alexa, you can then select how you'll build your skill—whether with the Smart Home Skill API or with the Custom Skill API.

Choose How Alexa Works with Your Device

Alexa Built-in

Build devices using the Alexa Voice Services (AVS) that customers can talk to and enable access to cloud-based capabilities, including music, information, smart home control, and more than 100,000 Alexa skills.

Alexa Connected Devices

Connect your devices to Alexa and enable customers to control them through hundreds of millions of Alexa devices. Customers can use their voices to control smart home devices such as lights and cameras, plus Alexa Gadgets and more.

Select How You'll Build Your Skill

Smart Home Skill API

Use the Smart Home Skill API to access capability interfaces that enable you to describe your device’s functionality and the properties, events, and directives that they support. Leverage dozens of capability interfaces to support a range of functionalities for you device, such as turning off or dimming a light.

Custom Skill API

With the Custom Skill API, you can build your own voice interaction models from scratch to support additional features beyond those provided in the Smart Home Skill API.

Multi-Capability Skills

With Multi-Capability Skills, you can combine the Smart Home and Custom Skill models into a single skill. Extend the built-in Smart Home skill utterances with your own custom voice interaction model to support nearly any feature, without customers needing to enable and invoke two separate skills.

Other Ways to Build for Smart Home

Alexa Connect Kit

The Alexa Connect Kit (ACK) allows you to connect devices to Alexa without worrying about managing cloud services or complex networking and security firmware. Instead, you integrate the ACK module into your product and pay a one-time fixed cost. ACK provides the managed services, software, and tools you can use to develop and manage your Alexa-connected smart products on an ongoing basis.

Echo Plus Zigbee Support

The Amazon Echo Plus has a built-in smart home hub that seamlessly connects and controls Zigbee smart devices, such as light bulbs, door locks, in-wall switches, and plugs, without the need for separate hubs or a smart home skill.  

Alexa Gadgets

You can also build your very own Alexa Gadgets—from smart toys to smart clocks and more—that pair to compatible Echo devices via Bluetooth using the Alexa Gadgets Toolkit.


Key Features of Smart Home Skills
