Smart Home Charger Guide

Device TYPE

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 synonyms and aliases.

These are our recommendations for traits on this type of device, however you are free to mix and match from all available traits to best match your existing product functionality.

Please see each individual trait document for implementation details like required attributes, EXECUTE and QUERY.

Sample SYNC Request and Response

This is an example using the device type and traits above. It is intended to give an idea of how to build a SYNC response. If you add or remove traits, this will need to be modified to reflect those changes.
