Automatic driveway lights via motion sensor. Automatic house fan (when in saves me money on heating or cooling). Light assisted alarm, makes the bedroom lights 10% brighter a minute before the alarm goes off. Pretty amazing how cheap things are these days, an arduino or Pi 0w and some relays can do quite a bit. Just bought a opengarage.io and considering the opensprinkler.
