Hello! I’ve just came upon this somewhat old thread and see my scripts disputed… 
If you’re still looking for a solution, please check another thread I keep up with:
As yesterday reported, my fork still works for Vorwerk (official Neato Binding never supported it). You only need your serial and secret obtained with my script above. You don’t need to create a bridge, just use both values with proper vendor vorwerk to create your Vacuum Thing.
