Bests & Worsts Reviews from Amazon

So the gentleman who posted the top review that says "Will not display the current temperature -- by design!" is incorrect at worst and misleading at best. I just installed one of these and it will display the current temperature, it's just not in huge numbers. When you walk up to the unit it will know you're there, and display what you have the heat/cooling set to and then will switch to the mode that lets you see what the temperature is. The temperature will be noted with a hash mark/notch and a number. I've included a picture here to show what I'm talking about and the stock amazon photo shows the same thing. If you look at my picture you will see where my unit is set to heat at 66 degrees and cool at 74. In between those numbers is 72, which is the current temperature. I also included a picture where I turned the dial to go to cool to 71 degrees and the display still shows the current temp at 72. In Amazon's stock picture the unit is set to heat up to 68 degrees and the current temperature is 65 degrees, as indicated on the upper left hand side of the picture. If you tap the unit it will pull up the main display screen which has the temp as well. Maybe the gentleman didn't understand the differences here or he had an older firmware than what it uses now. Regardless, I don't feel it's fair to knock this unit for not displaying the temperature even though it does. It's not in giant numbers, but it's pretty easy to tell what the current temperature is if you take a moment and look. The current temp is on dispaly immediately if you're looking at the unit. Now to the actual review. This unit was very easy to install, the big pain was getting my old thermostat off of the wall. Nest has a interactive website for the installation of this unit (nest.com/works) that makes it easy to figure out if your current wiring will support one of these newer thermostats. You log onto the Nest site and chose the wires that you have coming out of your thermostat and from there the Nest site will tell you if you can use the Nest thermostat with your current setup. I would suggest looking that up before you purchase this unit. Or if you too like to live dangerously, do what I did and pull up the site on your iPad after you've bought the unit. With that out of the way, the unit comes with a back plate that you will connect your wires to. Before you do this, turn off the power to your HVAC system. I like to live dangerously, but not THAT dangerously. Connect the wires to the back plate, attach the unit to the wall and flip your breaker. The unit will light up and guide you through a pretty easy set up. NOTE: You do have to have wifi to get this unit to work properly. If you do not have wifi do not bother purchasing this thermostat. The thing I like the most about this thermostat is I can set a threshold for heating and cooling. Every house I've lived in has always had thermostats that seemed like they were from the 1970s so I don't know if this feature is normal on new thermostats, however this is a game changer for me. Where I live the temperatures can vary by 40 degrees each day and having a thermostat that will let me run the ac in the evening and then turn on the heat at 2 am when the temp drops is worth every penny. I literally have set the thermostat and left it alone since installing it. Some other cool features of this thermostat are that it keeps track of how much heating and cooling you do each day if you're into metrics, and it has a feature called "Sunblock". When you install the thermostat it asks you where you're installing it (such as a bedroom, hallway, kitchen, etc) and if the unit is in direct sunlight. If it is the unit will use Sunblock, which uses the light sensors in the thermostat to determine when it's under direct sunlight. This is used to learn the sun’s patterns in relation to your house the temperature sensors to detect the heat spikes that occur in direct sunlight. It then links to your wifi and knows when the sun rises and sets in your area. Sunblock will use that information to set the correct temperature whenever it’s in direct sunlight and not waste energy. Again, this is a game changer. My previous house had a thermostat that was near direct sunlight and close to a computer so it would run the AC when it wasn't needed, and jack up our electrical bills. There's an app as well that lets you control the temperature if you're lazy and don't want to get up, and to set the temp in the house while you're away. Overall I think this is a really cool product, and if the features I've mentioned are something you'd be interested in then I think it's worth the money. It's especially worth it if your power company has a rebate for purchasing one of these units. That can bring the cost down $50-$100 dollars.
