## 4. Data flow: Cube → TTN → ThingsBoard

Simplified, the data flow can look like this:

Your measurement data from the IoT Cubes has been transmitted to the Internet, as these devices are already registered with The Things Network (TTN). You can access and view your live data on the TTN Console. If you're interested in this aspect, please visit the TTN Console. If you do not have a TTN account, create one TTN Login and contact Fabian Reifler to be added as a collaborator. The TTN Console looks like that:

TTN 1) serves as a LoRaWAN Network Server, connecting all LoRaWAN gateways and edge devices. It's important to note that data is not permanently stored on TTN but is forwarded. Currently, TTN forwards your measurement data using MQTT 2):

The data is retrievable via MQTT, which we implement using ClavisCloud. ClavisCloud is a hosted version of the open-source software ThingsBoard. It archives every message and provides functionality to create dashboards for visualizing the data.
