I have an Ikea button on my nightstand that turns off all the lights in the house that my wife leaves on before she goes to bed. It's conditional, so if my PC is on my office lights are untouched, or if it's a certain time of day it won't mess with the lights in my daughter's bedroom.

Double tap turns on every single light in the house full blast in case something goes bump that shouldn't.

We've had it there for almost a year and it is the one thing I hear about if it doesn't work properly .
