I posted something similar in an IoT thread here recently, but the main reasons I have them are for security (able to turn on/flash lights in parts of the house if my alarm goes off during the night. Also able to turn lights on/off using a schedule when I am on vacation) and convenience (when my kids were infants I was able to trigger lights on/off as I walked around at 3am. I've also used this when guests are staying in the house). Mine are all z-wave so still function as normal light switches that can be manually toggled on and off.
