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. Two-factor authentication is supported for all device types.
