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).
Air Freshener action.devices.types.AIRFRESHENER Air fresheners can be turned on and off and adjust various modes and toggles.
Air purifier action.devices.types.AIRPURIFIER Air purifiers can be turned on and off and may support adjusting fan speed levels. Some may also have various toggles or modes, and each mode has its own related settings. These are specific to the air purifier and are interpreted in a generalized form.
Blinds action.devices.types.BLINDS Blinds can be opened and closed, and various types of blinds are supported such as venetian (opens in one direction), panel or vertical (may open either left or right), and top-down bottom-up (may open either up or down).
Camera action.devices.types.CAMERA Cameras are complex and features will vary significantly between vendors. Over time, cameras will acquire many traits and attributes describing specific capabilities, many of which may interact with the video/audio stream in special ways, such as sending a stream to another device, identifying what's in the stream, replaying feeds, etc. As such, cameras also interact with other devices - especially screens and other media targets.
Coffee maker action.devices.types.COFFEE_MAKER Interactions with coffee makers may include turning them on and off, adjusting the target temperature, and adjusting various mode 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.
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).
Fireplace action.devices.types.FIREPLACE Fireplaces can be turned on and off, and may have adjustable modes and toggles.
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.
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.
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.
Refrigerator action.devices.types.REFRIGERATOR This type indicates that the device gets the appropriate icon and some refrigerator synonyms/aliases. Refrigerators are temperature-managing devices which may have various modes/settings.
Scene action.devices.types.SCENE Scenes defined here are partner scenes, implemented as virtual devices and activated by name.
Sprinkler action.devices.types.SPRINKLER Sprinklers can start and stop (or turn on and off). In the future, they may support timers and/or schedules.
Switch action.devices.types.SWITCH This type indicates that the device gets the switch icon and some switch synonyms/aliases.
Thermostat action.devices.types.THERMOSTAT Thermostats are temperature-managing devices, with set points and modes. This separates them from heaters and AC units which may only have modes and settings (for example, high/low) vs a temperature target.
Vacuum action.devices.types.VACUUM Vacuums may have functions such as starting, stopping, and pausing cleaning, docking, checking the current cleaning cycle, locating the vacuum, or adjusting various modes such as turbo mode, and toggles such as quiet. Some vacuums may support cleaning specific zones in the home.
Washer action.devices.types.WASHER Washers 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.

Washers also have various modes and each mode has its own related settings. These are specific to the washer and are interpreted in a generalized form.
