Device Grouping is also one of the functions of the Device Manager. Grouping or tagging a devices to a group enable you to send messages or commands in bulk to all devices associated to the group.
Before assigning your device to a device group, you need to create one first in your instance. To do this, navigate to Device Groups on the navigation sidebar and then click New Device Group. You will be taken to the New Device Group form afterwards.
Enter the name of your device group, and then click Create Device group. You should be able to see a notification saying that your device group has been created.
You can also assign a parent device group to your new group. All device groups assigned under a parent group will be able to receive the messages or commands sent to the devices associated in that parent group.
To do this, just select the parent device group from the drop-down menu.
