Adding Devices

This section contains instructions for adding devices in The Things Stack.

Class C and Multicast

Class C end devices continuously listen for downlink messages. This allows applications to send messages to devices at any time, instead of having to wait for a Class A uplink. When combined with multicast groups, this allows applications to send immediate downlinks to many devices at the same time.

This guide shows how to enable or disable Class C for an and device, and how to work with multicast groups.

Downlink Queue Operations

The Things Stack keeps a queue of downlink messages per device. Applications can keep pushing downlink messages or replace the queue with a list of downlink messages.

You can schedule downlink using the CLI, MQTT or HTTP webhooks.

This guide shows how to interact with the downlink queue from the command-line interface (CLI).

End Device Templates

End device templates define the blueprint of a device. Templates can be used to create one device or many devices at once. Templates allow for using common values for many devices, such as a device profile.

End device templates are primarily targeted at device makers and service providers who are managing and onboarding large amounts of devices.

In this section, learn how to create templates or convert from vendor-specific manifest files, how to map and combine templates, how to assign EUIs and how to execute the templates to create the end devices.

Generate QR Code

The Things Stack can generate QR codes for your devices. This helps identifying the devices and allows for claiming the device.

This guide shows you to generate a QR code for claiming with the command-line interface (CLI).

MAC Settings

This section provides guidelines for configuring MAC settings for end devices from the CLI.
