It's a nice and convenient way to monitor the temperature, once you've figured out how to link the Wi-Fi and sync Honeywell Home App. Otherwise you have full control from the your phone. In my case I linked it with the Apple Home App, to make it easier to adjust temperatures while I'm home.
This would be a 5 star review, lacking the smart learning. The interface takes a bit of getting used to, although it's all there in black and white. The other downside to this unit is a battery back-up to run the thermostat. If the power goes out, pretty much out of heat.
Overall once everything is set up, you can start scheduling the temps according to time of day and the days you want to keep the house warm or cool.
Difficult to program and needs constant monitoring to keep the temperature comfortable. Requiring a smart phone to make it work isn't the way to do it, and online instructions are inadequate.
