Hello,
Data to Server instance can be used to send the data to either the device's internal MQTT broker or an external one. If the internal broker is used, the IP address should be specified as 127.0.0.1.
The MQTT package can be found in the services section, and broker configuration is as simple as enabling it. If you do not see this package, it may need to be downloaded from the package manager found in Services → Package Manager → Packages.
If you decide to use the internal broker, please keep in mind that it requires either a public IP address or a VPN tunnel to access it remotely.
Best regards,
