Google Nest Thermostat E - Programmable Smart Thermostat for Home - 3rd Generation Nest Thermostat - Works with Alexa,White

Easy to install, I like the app and I get a discount from my electric company for enrolling in Empower Hour Program.

This is the way for vast majority of people. Really like to be able to connect to sensor and put in another room or area very handy with a toddler in his own bedroom.

I have to confess, I ordered this one by mistake based on the lower price. But I am extremely happy, it comes with its own wall base and it has more and easier access functions right on the panel .Thank you,Dr. Leonard

If you’re looking for an overpriced, poorly executed product that makes your house feel like far less than a home, this is it!This piece of junk costs you a premium and then requires far more adjustment than a manual thermostat… like several time a day adjustments… that makes no sense!?!It consistently works double duty by putting itself into ECO mode when we’re home yet somehow cools the house wastefully and runs up the electric bill when we’re not! There isn’t a day that goes by that I don’t have to stop what I’m doing and wonder “why is it so hot in here??” only to find the inside temp at 82 degrees or higher despite setting it at 76 an hour earlier. It also inexplicably adjusts itself 3-4 degrees lower than what I set it to at night which is ridiculous.Another huge nonstarter for me is a periodic message letting me know the thermostat I paid a premium for is “working in partnership with” my Electric Co-Op to conserve energy by setting the temperature in my house to somewhere in the sweltering range despite having an energy efficient AC system that’s less than a year old. I have tried repeatedly to disable this feature and cannot find a way to do it either in the app or the touchscreen. Hey Google, why isn’t my “smart” thermostat working in partnership with ME to make my home liveable??This is a terrible product and has been replaced with a much cheaper product from another company that stays where it’s set, is easy to schedule through its remote app, and doesn’t work against me by pretending to be “smart”.Save your money, this thing is garbage and the entire division who came up with it at Goofle should be canned!!

I'd give it 5 stars except for the fact that IT NEEDS A HOLD FEATURE! Every non-cloud-based scheduling thermometer I've had over 30 years has had a HOLD setting, which keeps the set temperature until you put it back to AUTOMATIC. None of the Nest thermometers has this feature, nor do the Honeywell cloud-based thermometers (which I had in a previous home and liked a lot.)I prefer setting the schedule myself to using the learn mode, because we just had too many exceptions and it got confused. But if you're a habitual person, and if you're the type to remember to set the temp the way you want it every day for a week or two, the learn function could be great. Furthermore, you can set it in learn mode, and then later adjust the learned schedule to what you want and turn off learning.I like that I can monitor and control remotely. I love the fact that I can change the temperature after I've left for a vacation and forgot to set it to away mode. (It has a feature to detect this automatically, but that doesn't work for us for reasons unrelated to the Nest.)One of my favorite features is for a finished attic, where we have a separate heat-pump HVAC. During the day it's a hobby/projects room, never used at night. Normally, heat pumps with auxiliary or emergency heat, you do NOT want to put them on a schedule (for example, lower the temp a lot on winter nights, bring it up to 65 during the day) because when the thermostat calls for heat in the morning, it'll use the expensive auxiliary heat to warm up as soon as possible. The Nest has three modes: fast as possible (max comfort), heat-pump-only (max savings), and a "balanced" mode that's between these extremes. I use the max-savings mode for the attic, which is perfect. I also have the "anticipate" feature turned on, so that if it takes 3 hours to get the room up to temp by 10 AM, it'll start at 7AM (and it figures that out.) So, I save a lot of energy/money.The Nest has the most thorough documentation of the features, better than I've ever seen for such a sophisticated device. It has LOTs of features and many of them are perplexing. The Nest website has excellent descriptions of each feature, not only explaining why you'd want to use it, but tips on how it works so you can really understand -- yet doing this in layman's terms. That's a really hard thing to do well, and I've never seen it done better.The hardest part of installation was that I didn't know exactly what type of heat system I had. For simple/normal HVAC systems with just one type of heat, one type of cooling, and just 4 wires (common, heat, cool, fan), installation is a breeze and the app walks you through it. Anyone who's just a bit handy can do it. If you have a more complex system, your normal HVAC guy can either do it, or answer the questions about what the wires are (that you need when there are special ones like the B/O wire, which can be used for different purposes.) You DO want to know whether you have a common, and if you don't, it's probably best to hire a pro if you're not a do-it-yourself type.I've put in 4 of these, and only on one did I have any doubts.I have both the normal Nest, and this unit which is the E lower cost version. There is one feature it doesn't have that I don't recall and don't need. The display is fuzzy compared with the normal Nest, but that doesn't bother me. I prefer the lower cost of these units.It integrates well with Google Home. It can work with an additional wireless temperature sensor, which is handy when the thermostat isn't where you want the temperature to be. Unfortunately, you can't ask Google what the temperature of the sensor is, just the thermostat. Maybe they'll add that before long.

My old thermostat stopped working and my brother suggested a nest. This is a great thermostat since it can be controlled manually or through your phone. This has the advantage that you can set the temperature when you are away from home. I had a professional install it and downloaded the App and was all set.

My house had only red and white thermostat wires (no C-wire). This device works great and does exactly what I want it to do. The only issue i had is probably because this is an older generation (gen 3) and the battery was drained- probably from sitting on a shelf for a while. As a result, the device would not power up through house wiring. I thought the device was defective. I found on Reddit that others had similar problems. The solution was to charge the battery of the thermostat with a USB plug-in charger (USB-Micro on the back of the puck). Once I let it charge for about 30 minutes to an hour, I was able to connect the thermostat and it stayed charged with the house wiring. There are no lights on the device to say it is charging, but when it is fully charged you get a message to attach the puck to the base.
