It works as it is advertised. I selected it for its remote sensor functionality, which works as it should. But previously I had a cheap digital thermostat which showed the immediate history of how much a furnace or AC was on for the past week or day. This unit lacks that kind of functionality. Not so much smart.
Intuitive and easy to use from the panel and from the companion app. Needs a C wire - which for me meant rewiring from the HVAC unit to the wall location - but easy enough to do. It did come with an adapter for use with old wiring, but I preferred not to use it. Very flexible - especially if you get the additional remote wireless thermostats that detect temp, humidity and presence. In my book this is better than Nest or Ecobee as long as you are willing to spend an hour programming up your preferences. It doesn't try to learn your usage - but if you already know exactly what you want it works very well and is very flexible
Very easy to setup and program. It practically does it all by itself. All you have to do is tell it what temp you like during the day and when you sleep. It does everything else. The two extra thermostats really make it work well.
