There is a demo app in the appstore: https://appstore.home.mendix.com/link/app/108810/Mendix/Siemens-MindSphere-Pump-Asset-Example
And there is also some tutorials about mindsphere: https://gettingstarted.mendixcloud.com/link/module/280/lecture/2196
But have not used mindsphere myself. Normally I would advise to use a dataview that listens to the selected object. And from there you can use a datagrid again to retrieve all the children that are attached to the object in that dataview.

The used “MDSP Asset View” is based on the Mindsphere WebComponents described here:
https://developer.mindsphere.io/resources/mindsphere-webcomponents/index.html
Unfortunately the component does only support filtering based on AssetTyp not parent asset id.
Maybe you could use the tree – view mode of the component on your home screen. Child assets are then shown in a tree. This will also keep the master / detail pattern.
