If you have more than one Echo they are each named, say name of a persons room, you can then ask Alexa in the room you are in to drop into say Sarahs room, it gives a slight ping in Saraha's room to let her know that a conversation is about to start, she could cancel it or wait and continue the conversation with you, either of you at anytime can say Alexa stop and it turns the microphones off, we have screens in all our room so you can also see and talk the screens can be turned off as well as the whole unit put in privacy mode, for a big house its brilliant, no more shouting, it would be worth getting a small Echo puck one to try the system out, they are £18.99 or something on the current deals and are great bits of kit, low profile but great sound for what they areYeah, for 60 quid I'm VERY happy. And thanks for the info mate. I'll check it out.
Have a great weekend!
