I am just happy to have a thermostat that I can easily program through a zwave hub and interact with my other devices. It's also nice to use presence for setting the temperature. The Nest was very appealing to me as well, but would not work in my home due to not having a c wire. This thermostat can do everything Nest can do, but may require more effort. It is also a lot cheaper than Nest.
Easy install wiring
Easy to setup to SmartThings v2 Hub
Liked the display.
Did not work with Emergency Heat. TRANE X13 4TEC3F36B
Not very tweakable as in settings were basic and not adjustable.
We did not have a C wire at first and used the thermostat with batteries but they only lasted a few months.
The two year battery life in the product description must be when connected to the C wire (C = Common)
Fortunately there was an electric wall plate close to the thermostat which included a Neural AC wire behind the cover. All I had to do was run a piece of thermostat wire from here to the C terminal on the thermostat.
NOTE: I did that after first checking if the Common terminal on the furnace was ringing out to the neutral wire behind the wall plate. In other words I measured no resistance - concluding that the two are connected somewhere else - most likely in the AC breaker panel.
Do not use a ground wire as this is illegal.
You will need a simple ohm meter to measure for conductivity.
You can find an inexpensive meter here on Amazon like the AstroAI Digital Multimeter with Ohm Volt Amp and Diode Test.

Now the batteries are providing backup in case of power failure.
I hope this review can help you avoid the trouble of running a separate C wire from your furnace.

I have it working with my Smarthings system, you won't find a Z-Wave thermostat even close to this price on the market.
