I tried the voice recognition, it does nothing for differentiating commands from different people. Most I have had it do is now and then address me by my name when responding to a command, i.e. OK, Have a nice day Tom. I am sure way down the road they have some AI ideas for it, but as of now its not a big deal. Naming in the bedroom I try to keep devices that are on my side named Toms Light, Toms Lamp, etc. My wife's side Barbi's Ligh,t Barbis Lamp etc. Shared items Our Light, is bedroom ceiling fan light, Our fan is bedroom ceiling fan, Our TV is bedroom tv etc. Lighting in Living room is End Table, Sofa Table, Floor Lamp, etc. Tried to make it simple and the wife uses it fairly well, without much trouble or complaining.
