Smart Home Charger Guide

action.devices.types.CHARGER - Interactions with chargers may include starting and stopping charging, and checking the current charge level, capacity remaining, and capacity until full values.

This type indicates that the device gets the Charger icon and some related synonyms and aliases.

Device capabilities

Refer to the corresponding trait documentation for implementation details, such as attributes and states that your service should support, and how to build EXECUTE and QUERY responses.

These traits are recommended, if applicable to your device. However, you are free to mix and match from all available traits to best match your existing product functionality.

Example device: Simple charger

This section contains example intent payloads representing a common "Charger" based on the device type and traits above. If you add or remove traits in your implementation, modify your responses accordingly to reflect those changes.
