GoogleNest Thermostat E - Programmable Smart Thermostat for Home T4000ES - 3rd Generation Nest Thermostat (Frosted White)- Compatible with Alexa

This thermostat was super easy to install and set up. I wired it, popped it on the mount, entered my information, let it update, left it on automatic "learn" schedule and just let it rock. My house doesn't have any returns for the forced air system upstairs, so the upstairs gets very hot in the winter at night and the heat runs a lot. The remote temperature sensor (which comes with this kit) solved this problem very well. I have it set to work off the upstairs temperature sensor during the "night" schedule which by default is 10pm to 7am, which ended up being perfect for us. It makes the upstairs so much more comfortable at night and the heat runs a lot less. Just a quick catch-up when it switches back to the downstairs thermostat in the morning. Adding the remote temperature sensor in the settings is also a breeze, especially with the Nest app. And overall, it seems like this thermostat works more "smoothly" than the cheap battery-powered one we had before. The heat doesn't seem to run as long and create as many uncomfortably high temperature events as the old thermostat. The occupancy sensor and automatic "away" eco temperature settings also work very well. It almost immediately recognizes when nobody is home and switches the settings. We also have central air, so I may post an update on how well it works with that when summer comes.Note about installation: This thermostat is powered by the furnace, therefore requires the blue "common" wire to charge the thermostat battery. I thought I was missing the blue wire but it turned out the previous installer just cut it back at the cable sheath. I simply slid a little more slack through in the basement, re-stripped the cable, and got the blue wire back. Note I also precharged the thermostat with the USB micro port while I was working on fixing the wiring. Not sure if that was necessary, but it was completely off/dead when I received it.

Easy to use, simple to install. It learns fast, be sure to train it well. May not work with older low voltage systems.

The thermostat I received was defective. Once installed, it would not turn on. I ensured it was installed correctly, charged the unit...still nothing. Returned for a refund 10 days after ordering and have yet to receive a refund. I have contacted the third party seller (MINHA-NY) and hope to hear back from them very soon.

Best thermostat I have ever had

The media could not be loaded. We have had this for years now, 2 of them to control the different systems in our house. Upstairs and downstairs. They are nice looking, easy to set up, and compatible with older homes. The only downside is that our one keeps losing charge which might be an issue with the power supply. So it’s compatible but not ideal.

Purchased 2 of these as they came with sensors. Product is great but they dud not ship the bundled version with sensor.

My adult kids dragged me kicking and screaming into a fully automated connected-home, including the Google Nest thermostats. What was I waiting on? I love the ability to raise or lower the temp from my bed; switch from heat to cool or cool to heat; or just turn on the fan. All from the comfort of my bed, sofa or kitchen table. It also has unlimited scheduling ability, so you can tell it when to turn on, turn up, turn down, whatever. Plus it learns your cooling/heating preference as you adjust your heat/cooling throughout the day, and automatically adjusts your schedule for you. My wife loves the white, low profile mount. She thinks the metallic one looks tacky and bulky. This one is sleek, modern and disappears/blends into the wall.

Makes keeping my house cool so much easier !
