Sonos have never been about reacting. I've used it as a Source for years. It has done a decent job of providing streaming services into a system. I will NEVER rely on it to provide the primary user interface into a system... because I have ZERO control over it and Ultimately, when a client gets confused because Sonos changes the app 5 times in 6 years, its my fault.

Alexa interfaces with my Control4 and Savant systems. Its a passable secondary interface for some folks.

of course, it still plays at my home as well. But we have the benefit of working with different products every day. We [hopefully] have some patience when it comes to user interfaces.
