Do you at least have the volume set at a low level, like 10% or 20%, so that if nobody is in the family room, it doesn’t wake anybody else in the house up? But yes, if you had a presence sensor in the living room, then you could do it on the condition that there was somebody in the room.
The way I see it is trigger at midnight. If presence is detected, set Alexa volume to 10% and announce, hey, you should probably go to bed.
Hmmm. Good point. I dont really see a way around that one though.
If the living room has smart lights you could turn them to red if a person was detected at midnight
