My Question or Issue

I am brand new to the service, getting ready to purchase speakers. If I purchase three speakers and put them in separate rooms of the house, will the app automatically play all three speakers when I select device, or will I need to select all three devices through the app?

If if I want to have this as my default set up, can I stream to say just one speaker in the bedroom when I go to bed?

Also will the Sonos one speakers work for this, or does anyone have any other suggestions?

Any help is appreciated.
