I'm super happy with my Ecobee. On multiple occasions I've gone on long trips and forgotten to put the A/C on vacation mode. It's real nice to be able to control it from my phone. Similarly, the City of Austin has an energy savings program in summer where on hot days they will (with your consent) remotely turn up all connected smart A/Cs by a few degrees, which drastically reduces strain on the electric grid. I think I got $75 when I joined. And it can be overridden, so overall it has been a great boon.
