Does the Nest e send out notifications in the event of extreme temperatures? Cold or hot. Can a group control the e?

Asked by: dugg
You can totally control the Nest from your phone anywhere . I don't believe it sends out messages in regards to extreme temps. You certainly will know the temp in your house.

I presume these smart thermostats show the house temp while you’re away, on the app.?

Does this model require a C (third) wire to work???

Asked by: Boxes
Most systems don't require a third wire, or a common wire, to work with the Nest Thermostat. If you have a two wire system, like a wire for R and a wire for W or Y, these systems can work with no problems for just two wires.

Can you set this next product manually?

Asked by: Manitoulin
You can manually change the temperature and other settings directly from the Nests display so you can control the Nest E from the device itself or through the Nest app.

Do you get fault messages displayed on heat pump applications?

Asked by: Nails
No, I personally have not encountered this error message. My system is relatively simple and has only a R and W connection. It was the simplicity of my heat-only system that made the Nest Thermostat the best viable option for my home. I hope this helps!

Smart Thermostat E - Wi-Fi - White is rated 4.4 out of 5 by 191.
Rated 1 out of 5 by from BE VERY VERY CAREFUL I used the Nest compatibility checker before I bought and after I installed it and went to connect it I found out it was NOT compatible. Even the Help Tech guy I called at Nest said it was compatible when he ran it through the checker (I emailed him a photo of my wiring even). If you have 2 Hot wires (a wire connected to the RC and RH terminal - see photo I attached to this review) connected to your existing system then this unit is NOT compatible. You will need to buy the 3rd Generation unit. I left a 1 rating only because you must leave a rating to submit your review. I believe that system is good but I did not get to use it.

Rated 5 out of 5 by from Easy Peasy We moved into a home that had an old thermostat... that we could not figure out! We researched different thermostats , asked for help at the store, and we purchased the Nest E . It took my hubby about 30 minutes to swap out and get it hooked to our WiFi . We LOVE how easy it is to read, how super easy it is to set, and we can control it from an app on our phones. It lights up if you get near it to let you see the temp, and you just turn a dial to adjust, or, even better you just adjust it on your phone. It has an eco setting and it keeps track of the temps and gives you averages. A great purchase for a reasonable price! [This review was collected as part of a promotion.]

Rated 5 out of 5 by from Should have purchased sooner! No more getting out of ben every night when the wife asks what the temperature is set on. Easy to adjust right from our phones from anywhere. Install took 15 minutes with no wire cutting. Setup website was great for confirming my system was compatible and giving me the correct wiring for my Nest E. Went back and picked up a second one 3 days later for my second floor.

Rated 5 out of 5 by from Amazing I am so pleased. Seriously, . . . it is amazingly easy to install. Wifi works great. Dads, you will love that you can use a PIN to lock the unit so only those with the PIN number can change the settings. Excellent scheduling capabilities. Great design. For those times in the fall and spring when you might need heat or AC, it will automatically turn on the furnace or AC, no need to flip a switch. The app is easy to use and setup with the app was amazingly simple. App has excellent simple interface. I could not be more pleased. I had a nest camera and all are controlled in same app. Best purchase ever! [This review was collected as part of a promotion.]

Rated 1 out of 5 by from HORRIBLE!!!!! Save your money!!!! This product is horrible. It worked at first and we were living it. Then it would get up to the temp it set at then while i was looking at it change to a temp four degrees lower! It also startrd this count down to turn on thing and would kick unit on then off!!! Hvac guy came out unit is fine.its just nezt. He recommended a honeywell thermostat. Works perfectly!!!! Ps.the nest customers service peopl are HORRIBLE!! They said was my unit etc. Did nothing to help. Told them what was happening with degress change etc. They could care less. I dont want anyone to waste their money like we did.

Rated 5 out of 5 by from Nice thermostat, easy set up. I bought this as the Deal of the Day. It ended up being over $100 cheaper than the Nest 3rd generation Learning Thermostat (which I have on the upstairs heat pump). This one is not built as good as the more expensive model (its plastic vs metal), but I knew that going in. I wanted the ability to control it from my phone or iPad and be able to set the fan to run for 15 minutes every hour. The old Honeywell thermostat didn’t have that capability. If you have more than one Nest thermostat, you can see and control both on the app on your phone. If you are looking for a WiFi thermostat this one is definitely worth looking at. Most of these type things can be found cheaper around Black Friday, but always check the Deal of the Day on Lowes.com and you might find one on sale!

Rated 5 out of 5 by from Excellent. Looks good, easily installed and simple to learn. Replaced an old rectangular Honeywell thermostate... The Nest e looks so much better. The step-by-step detailed instructions allowed for easy, quick installation. The ap is great and can integrate with Xfinity Home and Amazon's Alexa. Well worth the price.

Rated 2 out of 5 by from Temperature fluctuated greatly Installation was easy but after it was installed it never worked right. If the temperature was set to 70 it would go down to 62 and still not turn on. When it did actually turn the heat on it would stop and start 4-5 times in the span of 30 min instead of just staying on to get the house up to temp. I would also constantly hear my furnace start to turn on then turn off again. How is this supposed to save any money? This photo is the amount of time the heat was on in the 2 days I had it installed.
