The Devices export contains information about the Fitbit devices used by participants. Each entry contains data about a single device. There may be multiple devices per participant.

The data in the Fitbit export is obtained through the Fitbit API. The available data will vary based on the device capabilities and the user's privacy settings. See the Fitbit "Get Devices" documentation for more information about using and interpreting Fitbit data.
