I have six Metro Toggle tiles that are connected to different Hue Scenes. What I want to create is when I press one button, the other ones turn to false.
How can I achieve that?

What I really want to create is a VIS screen which has 6 buttons which represent Hue scenes. So when I press one button that scene will activate and the other buttons will deactivate. I need help with that deactivation part. Do I need a script or is there a non-script way to achieve it?

@opossum I'm trying to get your visualisation imported but whatever I try I'm still getting a 'blank' screen.
I've installed all the widgets/adapters that you've mentioned and even made a new ioBroker instance on my 'spare' raspberry pi (instead of my ioBroker on my Synology NAS in docker).
This is what it looks like.

What am I doing wrong?
ps. you can answer in German...
