module: meraki_device
short_description: Manage devices in the Meraki cloud
description:
- Visibility into devices associated to a Meraki environment.
notes:
- This module does not support claiming of devices or licenses into a Meraki organization.
- More information about the Meraki API can be found at U(https://dashboard.meraki.com/api_docs).
- Some of the options are likely only used for developers within Meraki.
deprecated:
  removed_in: '3.0.0'
  why: Updated modules released with increased functionality
  alternative: cisco.meraki.networks_devices_claim, cisco.meraki.networks_devices_remove and cisco.meraki.networks
