Welcome to the Google Home Developer Center, the new destination for learning how to develop smart home actions.

Smart Home Device Types

Smart home supports a number of different device types. Pick one that best aligns with your particular product.

Device types harness the power of the Google Assistant's natural language processing. For example, a device with a type light can be turned on in different ways:

Turn on the light.
Turn my light on.
Turn on my living room light.

The functionality for device types comes from the traits that you add to each one. Each device type has a number of recommended traits, but you can add whichever ones you want. Secondary user verification is supported for all device types.
