My absolute favorite that has proven to have the highest WAF (Wife Approval Factor): Motion sensors that turn on the light in the laundry room. All of us do laundry and it's amazing to not have to shift any load you're carrying to try and flip a light switch.
Most people aren't going to consider a utility room to be a good target for automation, but this has been pretty major for us.
