Need idea... trigger for sleep mode

Oh boy, oh boy. I always love when I can share this. It's my pride diy modification. I modified two contact sensors (very easy) to trigger with buttons when our phones are docked and undocked. When one goes to bed, the house goes to quiet time, which turns off most of the lights in the bedroom and turns on the fan. When the other docks the phone and goes to bed, the house turns off and night mode is engaged. Just with two tiny buttons rigged to a contact sensor. When no phones are docked = home when one phone is docked = quiet time, 2 phones docked = night mode. Here is a link to my project. Maybe it will spark some imaginative diy project for night mode.
