Sending a downlink allows to control or configure physical devices from the cloud. The downlink action can be used to send downlinks based on applied business logic. For example, if the temperature exceeds a certain threshold then close the blinds.

It is possible to select one or more MQTT- or LoRa devices with the same Data Flow for which the downlink should be triggered.

Sending downlinks is only possible for MQTT- and LoRa-devices. It is not possible for HTTP-, CoAP- or Sigfox devices.

Following downlink message type has to be entered for:

  • LoRaWAN

    • port (an integer value)

    • confirmed (a boolean value)

    • payload hex string or JSON object (requires a downlink encoder in the device type)

  • MQTT

    • topic (a string) - The optional topic added here will be appended to the downlink topic to which the downlink is published to e.g. when providing "myTopic" the resulting downlink topic will look as follows: /down/<secret>/id/<deviceID>/myTopic.

    • payload as a JSON object - it is possible to use template variables "key": "{{data.temperature}}".
