I still think it is funny how much people like the next when you can easily program a regular thermostat. I dont really need to change my temperature when I am driving home.
I love my Ecobee 4. It does much more than that. It can learn your habits, mine can tell when I am home via motion sensor. I can set it so it knows if I am on vacation and within a few miles of home, turn the A/C on to cool down the house. I can set it or adjust via voice.
I will never go back to a "normal" thermostat.
