It is possible if you have the SmartTiles code. Create a smartapp and replace https://graph.api.smartthings.com with https://graph-eu01-euwest1.api.smartthings.com
It’s also possible to get the api endpoints to work. ( Tutorial: Creating a REST SmartApp Endpoint )
Just replace all links the same way.
Sure, if it all worked out of the box it would be better, but this “workaround” is good enough for me at least.
