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.

Device Device Type Description Recommended Traits
Air conditioning unit action.devices.types.AC_UNIT Air conditioning units are similar to thermostats, but do not support heating and may not support setting temperature targets, but rather rely on modes, toggles, and fan speed settings (for example, high and low).

Dehumidifier action.devices.types.DEHUMIDIFIER Dehumidifiers are devices that remove moisture from the air. They can be turned on and off, report and adjust target humidity, and may have various adjustables modes, toggles, or fan speed settings.
Dishwasher action.devices.types.DISHWASHER Dishwashers can have start and stop functionality independent from being on or off (some washers have separate power buttons, and some do not). Some can be paused and resumed while washing.

Dishwashers also have various modes and each mode has its own related settings. These are specific to the dishwasher and are interpreted in a generalized form.
Door action.devices.types.DOOR Door can be opened and closed, potentially in more than one direction .
Dryer action.devices.types.DRYER Dryers have start and stop functionality independent from being on or off. Some can be paused and resumed while drying.

Dryers also have various modes and each mode has its own related settings. These are specific to the dryer and are interpreted in a generalized form.
Fan action.devices.types.FAN Fans can typically be turned on and off and have speed settings. Some fans may also have additional supported modes, such as fan direction/orientation (for example, a wall unit may have settings to adjust whether it blows up or down).
Faucet action.devices.types.FAUCET Faucets can dispense liquids in various quantities and presets.
Fireplace action.devices.types.FIREPLACE Fireplaces can be turned on and off, and may have adjustable modes and toggles.

Gate action.devices.types.GATE Gates can be opened and closed, potentially in more than on direction .
Heater action.devices.types.HEATER Heaters are similar to thermostats but do not support cooling and may not support setting temperature targets. Heaters may rely on modes, toggles, and fan speed settings.
Hood action.devices.types.HOOD Oven and range hoods can be turned on and off, may have adjustable modes, and may have adjustable fan speeds.
Humidifier action.devices.types.HUMIDIFIER Humidifiers are devices that add moisture to the air. They can be turned on and off, report and adjust target humidity, and may have various adjustable modes, toggles, or fan speed settings.
Kettle action.devices.types.KETTLE Kettles are devices that boil water. Interactions with kettles may include turning them on and off, adjusting the target temperature, and perhaps adjusting various mode settings.
Light action.devices.types.LIGHT This type indicates that the device gets the light bulb icon and some light synonyms/aliases.
Lock action.devices.types.LOCK Locks can lock, unlock, and report a locked state. Unlocking is a security sensitive action which can require two-factor authentication.

Outlet action.devices.types.OUTLET This type indicates that the device gets the plug icon and some outlet synonyms/aliases.
Oven action.devices.types.OVEN Interaction with ovens involves the ability to bake or broil at certain temperatures. The physical temperature inside the oven differs as the oven is heating, so this may also be monitored. The oven has a cook time that limits the duration of baking.
