...and what do you expect?
If you want a proper "smart home" solution, you have to get an integrated package. Those aren't cheap and aren't things you can generally get via amazon.com.
I spent way too much on mine. But my outdoor lights turn on at 15 minutes before sunset and turn off at a random time between 10 and 11pm. I've got a couple thermostats which will warm up the first floor on weekdays to 66 degrees on weekdays half an hour before I go downstairs in the colder months. Also have a music system that can play any playlist off my server in any room of the house, or play a radio or internet radio station or even the audio of a TV station. Everything via physical switches or via a phone app.
Systems in the future will do more and cost less. Hopefully they'll be as secure and integrate as well or better than what I have now.
Is it worth it? Of course not. (Well, it may be worth it so that I don't have to turn off the outdoor lights when I'm already in bed. Because there's no way my wife's getting out of bed for that.)
