Mike, I think what he wants is if he is talking to the living room dot, and says "turn on the lights", the living room lights will come on. If he is talking to the dining room dot and says "turn on the lights", only the dining room lights come on.There's no easy way to do this. The Dot simply doesn't know where it is located or where lights are located, regardless of what one may have named them. One way to set up a specific Dot with a specific smart group is to have Dots on different Amazon accounts, and your smart lights on different accounts. Then connect the separate Amazon account with the separate smart light account. This may hamper other Echo activities like music accounts, etc. I've also read of people using several HA bridges to do this. However, it's not a "native" ability for the Echo devices and can get quite convoluted.
