Access hana database for SAPUI5 Dashboards

Hello community,

I have a SCP trial account (s-user) and I send sensor data to the Cloud using the HTTP-API of the Message Management Service. The data is stored in a hana mdc database. Now my problem: Is there any simple service/API I can use to access the data in a SAPUI5 dashboard? The tutorials I can find require installing SAP NetWeaver AS ABAP on a virtual machine to provide an OData-Service which seems to be very complicated to me for such a simple task. Maybe you can tell me which way this tutorial uses: https://blogs.sap.com/2015/10/26/the-cheapest-and-simplest-way-to-send-sensor-data-to-the-hana-cloud-platform/
Unluckily I can not have a look into the .class files of the java-Application to find out.
I am very grateful for any help

Best regards,
Niclas
