I stumbeled over a great integration at r/homeassistant at Reddit.
https://www.reddit.com/r/homeassistant/comments/1p9ydll/zigbee_mesh_floorplan_card_updated_released/
As i did not find it in these forum i thought posting here might help others not active in reddit.
It adds a lovelace card for visualizing the network of a zigbee mesh, with the great advantge of fixing the nodes on a floorplan.
It needs some manual editing but im rather happy with the result.
