As the switches are operated via WI-FI (Mobile app or Alexa) NO front buttons or switches are necessary, and I let the box front as is.
I didn't know if the aluminium box could block the WI-FI signal, and I was afraid of that. But fortunately they work very well and connect quickly when powering ON.
I attach some more pictures of the Box and a Full view of the Room when you can see the switch box in the equipment rack on the left, just below the 8500, with its bland white front. I have not yet put an interesting picture on the front.
Amazing “switch” and great looking HT.
