Can i use it like an intercom from one room to another?

Yes you can use it like an intercom. You will need to know the device name. So when you set up the Echo’s give them names you can remember. “Like Living Room Echo”, “Sally Echo”, Billy Echo”, “Laundry Room Echo”, “Breakfast Room Echo” etc… Then you can say “Alexa Drop-in on Sally Echo” and then that Echo will go into…
