Additional Discovery Response Examples
The Alexa.Discovery interface describes messages used to identify the endpoints associated with the user's device account. You send a Discover.Response event so that a user can discover the devices and scenes associated with your Smart Home skill. For details, see Alexa.Discovery.
The following are some example Discover.Response events. To see example discovery responses for other capabilities, see the documentation for each interface.
For more ideas about how to combine different interfaces in your Alexa skills, see Smart Home Skill Device Templates.
Example for a camera that supports pan, tilt, and zoom
The following example shows a Discover.Response event for an Alexa skill that controls a security camera, such as a front door camera or a nursery camera. In this example the camera supports the Alexa.RTCSessionController interface for communication between Alexa devices and the camera. In this example the camera can physically pan left and right, tilt up and down, and zoom in and out. The skill implements the Alexa.RangeController interface to support pan, tilt, and zoom.
A camera can support any subset of pan, tilt, and zoom. For pan and tilt, specify ranges as percent of the Field of View (FOV) of your camera. For example, if your camera has a 90 degree horizontal FOV, and can rotate 360 total degrees, the range of motion is 400%. You can define your total supported range as 0–400 or -200–200. Define the pan range as -200–200 so that 0 represents the center. The tilt range is -50–50, and the zoom range is 0–200.

Example for a fireplace
The following example shows a Discover.Response event for an Alexa skill that controls a fireplace. This fireplace uses the following interfaces:
- PowerController to turn the fireplace on and off.
- ColorController to change the color of the flames.
- RangeController to change the number of burners that are on.
- ModeController to provide campfire, candle, and ice flame modes.
This example is part of a tutorial that builds a Smart Home virtual fireplace skill in Python. For details, see Skill Sample: Smart Home Fireplace on GitHub.
This example provides friendly names that give users more flexibility in how they speak to Alexa. For details, see Friendly Name Resources and Assets.

Example for a thermostat that requires user verification
Note: Currently user verification is supported only for the (
ja-JP) locale.The following example shows a Discover.Response event for an Alexa skill that controls a thermostat. This skill uses the PowerController interface to turn the thermostat on and off and the ThermostatController interface to control the temperature and the mode.
This skill requires the user to verify any actions before Alexa performs them, therefore this Discover.Response includes a verificationsRequired object for each interface that supports it. For details, see the verificationsRequired object.

Example for a water heater
The following example shows a Discover.Response event for an Alexa skill that controls a water heater as described in Water heater.
In this example you use the ToggleController interface to support Alexa hunches. For details about hunches, see What Are Alexa Hunches? and Enable Alexa to Proactively Act on Hunches Without Customers Needing to Ask.
This example also uses the DeviceUsage.Meter interface that is intended to help users manage their energy usage with the Alexa energy dashboard. For details, see Smart Home Energy Overview.
