Even though the Hue app isn't great, the Phillips Hue lights are something I recommend to non-tech people I know as an intro to the smart home. I have them all over my house, and they pretty much never fail to do what you expect (just like dumb appliances). Wi-fi switches are great and haven't had to replace a battery yet after maybe 4 years.

I find waking up with the light slowly brightening so much better than an alarm, but just as effective.
