This works great with out nest thermostat. Out main thermostat is located in an upstairs hallway. When the bedroom doors are shut, there is no cooling circulation reaching the thermostat. As a result, rooms get extremely cold as AC never shuts off. We put this in one of the rooms, and now the AC runs as it should and rooms are cooled to chosen temp.

this sensor was very easy to hook up. The sensor also allows me to have consistent heat throughout the house. This is worth every penny. I am so glad I did not have to move the thermostat to another room.

The Google Nest Temperature Sensor has been a fantastic addition to my smart home setup! It’s super easy to install and syncs perfectly with my Nest Thermostat. I love that I can place it in different rooms to ensure the temperature is exactly where I want it. Now, my bedroom stays comfortable at night without having to adjust the whole house. The app control makes it so convenient to monitor and adjust temperatures remotely. It’s small, discreet, and works flawlessly. Highly recommended for anyone looking to fine-tune their home’s comfort level!

Amazing technology. It turns your house into a multi zone home without having to pay thousands to your AC company. It’s controlled by the app or at the wall mounted Nest thermostat.You are now able to pick which room controls the temperature in your house. It’s like the thermostat is in the room you choose. At night you can pick the bedroom and during the day choose the room you spend the most time in, say family room. Also in the app you can see the temperature in each room you have a sensor. Believe you can add 5 sensors.

I purchased this item and failed to install it because I needed a more recent version of the Nest thermostat, despite the fact that my thermostat was telling me I had the most up-to-date version.After some research I discovered that there are 2 versions of the software: 1 for the United States, Canada, Mexico, and some other countries, where this sensor is available, and 1 for Europe, which is not compatible with is sensor. This sensor shouldn't be sold in the UK as is cannot be used in with a UK-sold Nest thermostat. Frankly it should be put in the product description.

Il sensore di temperatura Nest non funziona in Italia, di questa informazione non c’è traccia nella scheda tecnica del prodotto scritta dal venditore (Americano). Dopo aver tentato l’abbinamento ad un termostato Nest “Learning Terza Generazione”, il termostato riporta un messaggio relativo alla necessità di aggiornamento del software, ma non è possibile fare nessun aggiornamento perché il software italiano non prevede l’associazione del sensore. Ho contatto l’help desk Google Nest, il cui operatore mi ha confermato che questo prodotto non è distribuito direttamente in Italia da Google proprio perché non è compatibile con il software italiano. Il venditore ha perso una buona occasione per dimostrare la sua onestà!

Let op met uw aankoop , dit werkt niet in Europa & wordt niet ondersteund in Europa !

They were easy to setup with the app and it's nice to be able to see the temperatures in different rooms and allow the Nest to turn on the A/C based on those temperatures. My Nest is in a hallway with minimal airflow, so it's consistently a few degrees over/under the normally occupied rooms in the house.Sadly, within the month I got it, one appears to have disconnected per the app and hasn't reported temperature to the Nest since it did. It's not because it's too far away because I moved it closer to the Nest and it still didn't reconnect, but I have another that is farther away and has several walls (at least three at an angle) and other obstructions/RF devices between it and the Nest and it works fine - it's not a distance issue. The other two have continued to function properly so far and I've had them since August 2021. Maybe it's just that the battery died in less than 30 days? The error it gives isn't very helpful: "Offline for over a day." It's been almost 11 months so far. Someday I'll troubleshoot it more.

Works well with our Google Nest 3rd Gen Thermostat (US version). Adding the sensor to the account was easy on the app, and connection is stable between floors (thermostat is downstairs, sensor is upstairs).

The Nest thermostat is algorithmic; this means it needs to know certain conditions such as are you home and this translates into motion detection by the thermostat and the use of your smartphone location as in being home or not. If the Nest thermostat were three sided, if the sides also picked up motion detection, a lot would be solved when it comes to the thermostat knowing you are home. A lot would be solved too if the thermostat's away from home and being at home but hunkered down for the night data points were on the ball. Until then, get the remote sensor.The Nest thermostat is heavy on using its app on your smartphone to know if you are home AND it uses a sensor to know if you pass in front of it. If you have just one thermostat in a two-floor house, or if you have multiple thermostats but you either stay to the left or right of any one of them or you are downstairs during the day or upstairs at night, a lack of motion detection wins out over the use of your smartphone showing you are inside the geofence of your home. This sensor is for one thermostat with one of four preset time periods (morning, afternoon, evening, night) that are fixed. You can choose just one of the four to prioritize temperature wherever the sensor is placed away from the Nest thermostat it is linked to. So if you have one thermostat for a two-story house, having a sensor upstairs to prioritize a pre-set temp of say 67 degrees from 9 pm until 7 am is great. Or if you have a child’s room, you can place the sensor there and prioritize your heat setting. The whole point of the remote sensor is to bypass the thermostat’s detection or lack thereof of people passing by it to show it you are home so the sensor can tell the thermostat what temperature you want at what time where. Of course, if you have say a second floor Nest thermostat and you want the child’s room to be 70 then yes, the entire second floor is 70. However this beats the thermostat going into eco mode (which you can set up to 65 degrees anyway on the thermostat even without a remote sensor) and keeping the entire second floor cold. In general, the Nest thermostat is good except for geofencing. It is not bad but it is not good. If during the day you are on a floor where you do not pass by the thermostat, it most likely will figure you are not there and go into eco mode. The result is you are cold, the thermostat’s temp is in eco mode, and you are not happy. The remote sensor is something like Civil War technology. It works, kinda. It does not detect motion. It only detects temperature in the room it is in and does absolutely nothing unless the prioritized zone and time period are in place. If you are downstairs most of the day, who cares if the upstairs thermostat goes into eco mode. If you are asleep at 10 pm and the thermostat thinks you are away, it goes to eco mode and you are cold. Yes the thermostat learns somewhat. Yes, it uses geofencing. Yes, it recognizes motion. Add the three together and Google does not yet have it right. Using this remote sensor lets you get a reasonable temperature staying put on the dial for a specific time period regardless of the thermostat’s going off the rails with its algorithms. I have two sensors: one is for the second floor from 9 pm until 7 am so I have the heat at 70. That is what I like. For central air, I have the thermostat in the second floor hall near the return. On the first floor it gets really hot from 1 to 6 pm. So a sensor on the first floor, linked to the second floor central air thermostat, gives me the chance to prioritize the central air thermostat setting to 66 which keeps the first floor bearable when it is 98 degrees out. The ability to prioritize the temp on the first floor with a second floor thermostat is great. After that at 6 pm, I don’t care if the Nest thermostat is bouncing around trying to figure out who is home and what it is learning. The Nest thermostat is hit or miss; the remote sensor helps it get a few more hits than before. I recommend it.

Although I'm sure in a larger home, multiple devices with timers set up would be very effective, in my new smaller, multi-level town home, the one I purchased has worked perfectly. The original thermostat I'm sure was in an easy location for the builder, but was also a distance from our most enjoyed room that is all windows and faces the blast of Winter from Georgian Bay (Wasaga Beach here) and also the direct afternoon sun. With this one device working as the "gauge" for the rest of the home, with some of the ducts closed, the basement is now much warmer (constant with the rest of the home) as is the upstairs and our windowed room is very comfortable. We have not needed the "timer" function, although it would be great with multiple units. I recommend this device if your thermostat is NOT in the most used room. Set up was very easy.
