Just bought a pair of these to use in my home as an intercom.Setting them up was a nightmare (technology challenged i am) and i had to call Amazon online help to get it done.They work perfectly,but by default they are named "echo dot" and "2nd echo dot". It would be nice if they were "master bedroom" and "family room".Is it as simple as going into the settings on my phone and editing the name to change it? Or will that bring about a total restart and more frustrating grief? I really suck at this stuff! I don't want to get my wife upset when i lose it.
