It’s not possible.  Apple doesn’t allow controlling 3rd party hardware from the hard buttons or lock screen, and the widget used on Android disappeared after the new app release last year. 

I remember that, 2 years ago that was possible. I controlled the beam with my phone android. I was sure that i changed this possibility with my phone or my sonos

Yes, it was possible. Currently it’s not, as explained in ​@jgatie’s post.
