I installed a Nest Learning Thermostat earlier this year in our new-to-us house. It had been functioning properly up until it started heating up in Florida. The thermostat is on the wall next to the garage, and there is unfortunately very little insulation on this wall. I decided to try the temperature sensor and mount it to the wall across from the thermostat in a more central part of the house. Setup was easy and took a total of about 5 minutes. After the temperature on the sensor stabilized, my A/C has been running less, and the temperature throughout the house is more stable. There is about a two-to-four-degree difference between the sensor itself and the Nest Thermostat. I can set a sensor schedule so that the system runs based on the sensor temperature during the day, and at night based on the Nest thermostat itself, and this works along with the temperature schedule I have set on the Nest Learning thermostat itself. Hopefully this little guy - along with having my A/C system serviced regularly (change your filters monthly and have an HVAC tech check your system annually!!) should help with my outrageous energy costs during the summer.

I rate this product as excellent, 5 stars, due to the face that this is the essential item to completing your Nest thermostat, and Smart Home. When we first purchased our Nest thermostat, we had trouble keeping the house a consistent temperature. If I had the heat set at 70, the upstairs would get to 70 and shut off based on the temp the Nest thermostat was reading at the thermostat. With some adjustments to our vents in the home by closing some off and opening others more, we now have it under control, but mostly thanks to the Nest Temp Sensor. Having the ability to determine which sensor is the primary sensor in the Nest application, makes this an absolute necessary purchase at its price point. We now are able to keep the basement and upstairs zero to one degree apart from one another. For anyone with a split level, two level, or multi-level home, this should be at the top of your shopping list when considering the Nest thermostat.

These little guys are so cool and go unnoticed if put up in the right spot but they're so smart and hard working. I just got my Nest Learning Thermostat and one of the goals was to better regulate the temperature throughout our 2 story townhome. It's one of those that it's hot in the bedroom, cold in the office, stale in the dining room, etc. I swear I noticed an instant difference within 2 to 3 hours of installing the thermostat and sensors. Not only that it made it all really easy to regulate and adjust in app via Nest, see the temps in Google Home and you can adjust the temp via Assistant (I'm sure you have a Nest Audio Speaker if you're purchasing this). I installed it pretty much right after the last billing cycle with Duke Energy and I'm hoping these tools can help with our energy costs. I suppose time will tell. However even if it stays the same, it's worth it for the control over the different zones. Plus you get a free NEST RENEW subscription which teaches you about going green, you earn leaves, I'm honestly not sure what all it does. I'm still learning the Thermostat abilities in app. And yes while I am the OFFICIAL-unofficial 'Google Guy' I say I Highly recommend the censors and the Learning Thermostat. (If for no other reason it's worth the extra $ for that hot stainless steel finish and gorgeous display!)

So I have google nest thermostat and then I got these to put around the house They will be very helpful if your house doesn’t heat or cold evenly In my case, the living room a kitchen heats much faster than the bedrooms in winter and my google nest thermostat is in the living room so when I set up the temp to 70 in winter the living room gets to 70f but the bedroom still at 65f which feels much colder However after I installed these, now when I turn on the heater or cold air, I can pick which temperature sensor I want the AC unit to look at So now I pick my office to be the main temp sensor and the heater or cold air will not turn off until that office temp sensor gets to the desired temperature I also can pick other temp sensors around the house, and you can just pick the google nest temperature sensor itself I think this a good product Also, you can monitor the temperature in the house even if the AC unit is not turned off

My building recently installed Nest thermostats. I have 2 HVAC units in my apartment. The built in sensor in the thermostat reads the temp in the room and kicks the HVAC on to restore the desired temperature. But the adjacent rooms were always too chilly. Wholah! I added an additional sensor to each of those rooms, and in my NEST app set which times I wanted the sensor to read the preferred room, the one with the thermostat, or the one with the sensor only. Now my thermostats keep my spaces closer to my preferred temp. You can see what each sensor is reading in the app. I'm pleased. Since I don't need my 3rd sensor, I gave it to friends to whom I gave a NEST thermostat w/sensor as a wedding gift.
