Hello Matej,
As per the information available, Azure doesn't have an option to export rules from IOT Central.
For configuration you can follow this link: https://learn.microsoft.com/en-us/azure/iot-central/core/howto-configure-rules?form=MG0AV3 For exporting the data from IOT Central you can follow: https://learn.microsoft.com/en-us/azure/iot-central/core/quick-export-data?form=MG0AV3
Thank you!
