You can view the list of all existing device groups in your instance by going to Device Groups on the navigation sidebar. You can look for your device group based on name using the Search function.
Once you've selected a device group, you will be able to see all available devices in that group. This can also be useful for obtaining the group ID which is located on the address bar of the device group's page. You can also do the following functions in the selected device group's page:
- Edit - Modify the name of the device group or change the assigned parent device group.
- Delete - Delete the device group. This will also detach the group from associated device(s).
The Device Group Manager also enables you to delete multiple device groups at the same time. Tick the box of your selected device groups, and then click Delete Selected. From the pop-out window that comes next, click Delete. You should be able to see a notification saying that your selected device groups have been deleted.
