Thanks for your feedback!
Regarding switches, I just looked and it’s a topic in its own right, so it’s outside the scope of this development. We can go into detail in another thread 
I invite you to create it if you’re interested!
Making the Sonos speak isn’t that complicated but I think we can keep that for a later time. I’d welcome a feature request as well to gauge interest!
I think we’ll deploy this first development as is to get more feedback, thanks again for all your testing
