    Bought two of these, one for my office, one for my younger child's bedroom. My plan? Simple - schedule the one in my office as the primary sensor while the kids are in school (work from home), and schedule the one in my daughter's bedroom to be the primary during the night (keep her comfortable), and then for pre/post school and on the weekends when they're awake, use the downstairs main thermostat as the primary. Here's what actually happened. Bought two of these sensors unpacked, scanned the QR code (note: if you buy more than one and take the tabs out and get confused as to which QR code goes to which sensor, take a coin and unscrew the back, there is a QR code on the inside as well. Had to apply more strength/pressure on unscrewing the back ring than I had anticipated...), added the new sensor to my Nest account/system. Tried to connect to the thermostat downstairs, kept saying it couldn't establish a connection, move the sensor closer. Kept moving it closer and closer until I literally rested the sensor on top of the actual thermostat and it still said it couldn't make a connection. That's when I unscrewed the back of the sensor trying to make sure the battery was seated properly, etc. It was. Tried again, failed. Removed the sensor from the nest account, tried to re-add and re-sync, no luck. Then I realized that (for the first time in probably ever...) the main thermostat was not connected to my WIFI network, and hadn't been for about 2 hours. Seems like something the setup of this remote sensor should check for... like maybe a "hey, seems like your thermostat has lost its connection to your home network, and that's required for setup of this newly added device". I rebooted the main thermostat and the connections worked flawlessly, even through a few walls. If you have the nest cameras (I have one in each kid's room), and you use the default labels "office, den, kids room, bedroom, whatever" and the labels match, it will show you the temperature in the room where the camera is, which is kind of a cool feature. Anyway, then when it came time to schedule the priority of all the sensors I was a little disappointed with how "locked-in" the scheduling is. You have the options to set priority of sensors by "night, morning, mid-day, and evening". The time periods are all locked and not adjustable. You also can not set priority by the day of the week, it's just one generic priority schedule for every day of the week with locked time periods. Seems like it wouldn't be too difficult to allow this functionality (And for that matter custom label names for sensor/camera/thermostat locations). Final thing to note is the sensor is a lot smaller than I was expecting. About the size of a flattened ping-pong ball, and very light. You also have the option of just putting it on a shelf rather than drilling a hole in the wall and mounting it. Should allow you to experiment with locations or change rooms easily if it's not working exactly the way you want it to. Overall, though, great product, does what it should. Took 1 star off because of the lackluster scheduling that could be improved, and because the setup process did not make a basic check to see if the thermostat was still connected to WIFI and let me waste about 30 mins trying to set it up before I found out myself.

    The frosting for a Nest Cake

    Our upstairs & downstairs each have separate HVAC systems. Being empty-nesters, our upstairs is seldom used. When it is, I’m too conservative to run the HVAC to heat or cool the entire upstairs at such times when only 1 of the rooms is in use. I had previous experience with an older Hunter thermostat which used portable sensors which could be used to determine which room would determine the thermostat’s temperature setting...like having separate thermostats in each room. The sensors could be used individually or combined to determine an average. I loved how useful & economical the sensor system was. The Hunter thermo eventually failed altogether. 6 mos. Ago, I replaced it with a Nest 3rd Gen Smart Thermostat along with a set of sensors which can be used to determine which of the rooms would determine the thermostat setting which when away from home can be adjusted remotely online. The room over the garage is the most difficult to keep temps adjusted and the room in the northwest upstairs corner is 2nds most difficult to keep adjusted. The thermostat is located in a room which has other rooms on each side of it insulating it from such problems. With these sensors, those rooms are now completely adjustable. I love being able to customize each room to accommodate usage by simply using or moving a sensor. I also love the economic advantages. Although the downstairs programmable digital thermostat works great, when we are away from home during extreme weather, I had to place a large visible thermometer in sight of a security camera so I could monitor the temp; however there was nothing I could do to make remote adjustments. Recently I decided to also replace our downstairs Honeywell thermostat with a 3rd Gen Nest Smart Thermostat with sensors. I plan on using the sensors to keep the temperature in certain more difficult to regulate rooms comfortable despite extenuating circumstances, i.e. north-west facing living room with 2 story cathedral ceilings and large north & west facing windows, i.e. a very hot kitchen with a hot-natured wife cooking & baking…all the time. The sensors, in combo with the Nest Smart Thermostat, are akin to the frosting on a cake. Using the Nest App I can monitor and make any adjustments online wherever we are!

    Perfect for hot zones and baby's room

    We have been Nest customers for more than 5 years and we hoped that they would add these a while ago. We moved in to a new build home about 2 years ago and found that some rooms of the house are cooler or warmer than others. The builder had the A/C flows leveled, which certainly helped, but we still have a temperature issue in certain rooms. These sensors work well, but they aren't quite what we were hoping. I included a few notes below..... 1- If you purchase the 3 pack, don't pull the tab to activate the battery until after you scan the barcode. I mistakenly pulled all the tabs and then activated them, but I didn't know which tab was for which sensor. The barcode should be on the item like the rest of the Nest products, not on a pull tab. I ended up having to place them in the sun one at a time to identify which one was for what room. 2- These work VERY well for us monitoring the temperature in our baby room. I will note to not place them directly adjacent to the vent flow, but rather as close to where the baby is sleeping as possible. They mount well and it was great to monitor the temperature in their room. 3- I really wish I could set the temperature to be controlled by different sensors in different parts of the day. I work from home and my office gets very hot at the end of the day. I would love to have it sync with that room during the afternoon and the thermostat for the rest of the evening. Likewise, it would be great to tell it to turn on if the temperature at ANY sensor reaches a certain level. This would be particularly useful when we are cooking dinner and I feel like I'm sweating to death in the kitchen. Perhaps the next version will add this useful functionality. 4- I love that it tells you if the room is typically hotter, colder, or about the same as the thermostat. Our thermostat is in a bad place and we frequently wonder why the A/C has or has not turned on. Overall, we would recommend the sensors and it is probably worth it to get the 3 pack. This feature was needed for a while and we are happy Nest finally offered these as an accessory.

    Great concept, poor implementation! Guessing a lot of people have this problem with forced-hot-air systems. The primary thermostat is on the main level and the (main) bedroom is on an upper lever - which, in the dead of winter/summer has a radically different temp from that main level. For instance, look at the uploaded pic. Main level is 63 and the Master Bedroom is 53. Not a problem during the day when no one is there but before bed you'd love to be able to set the Bedroom temp to what you like!? (yes single zone the the main level will get (much) hotter.) Nest will allow you to use the sensor for anyone (or all) of 4 pre-defined time slots (morning, afternoon, evening, night) BUT these times are preset and can not be changed. Pre-set times: Morning: 7am to 11am Midday: 11am to 4pm Evening: 4pm to 9pm Night: 9pm to 7am Sooooo, if I want to use the bedroom sensor to warm up the room, before bed, I would have to have the rest of the house sweltering from 4 to 9 or 9 to 7. Seems like - for as technologically advanced as these are; you'd be able to say bring my bedroom temp up to "X" at bedtime then revert back to the main thermostat!?!? Bottom line: for $40 bucks you get an expensive thermometer that tells you what the temp in that room is but really doesn't give you a way to truly "fine-tune" it.

    I have a two story home with only a single zone. The AC system does a pretty good job of keeping temperatures consistent through the house, but it does struggle in moderate weather when it's not running often. It's particularly problematic in the bedroom at night. The thermostat downstairs may think it's cooler than it really is upstairs. Even just adjusting the temperature down doesn't quite work - the temperature upstairs may climb 2-3 degrees before Nest decides its time to cool again. I had tried the Ecobee with its remote temperature sensors. This resulted in wonderful comfort in the bedroom, but their product is plagued with so many issues, one of which being that the Ecobee's remote sensors couldn't even work reliably 30 feet away in my home with almost no obstacles. So far the Nest version of the product is working well. It has no motion sensing option but I can't say I miss it since the Ecobee's didn't really work. More importantly, Nest's sensors range seems better, they are working fine to my office upstairs. Setup was quite simple, mostly scanning a QR code. The Nest app walks you through it. I had no issues. I'm giving it 4 stars because while great, I think they should expand on the functionality provided a bit. An option to average the temperature across multiple selected sensors would be a good idea. I think more customization with the scheduling instead of fixed time blocks. Motion sensor integration could still happen through other products ( Nest protect?). What's offered here happens to fit my needs pretty closely though. I'm happy its here, and I'm happy it works.

    great fix for nest thermostats in bad locations

    My house is roughly 90 years old and for some reason, somebody thought it was a great idea to put the thermostat on a wall within which hot water flows to and from the upstairs bathroom. As a result, the thermostat tends to read warmer than the actual temperature in the rest of the house. Enter the Nest Temperature Sensor. I replaced an older thermostat with a Nest 3rd Gen Thermostat and thanks to this additional sensor, my house is now comfortably set to a consistent temperature. Using the Nest app, I've noticed a 4 degree difference between what the thermostat *thinks* the temperature is and what the temperature actually is. Setup is simple - just open your Nest app, touch the gear icon, and touch "Add product". You can then scan the code on the battery tab and follow the app's instructions from there. Placement of the sensor is easy as well. During setup, the Nest app will tell you if the thermostat can't find the sensor. Just move it to a different location and re-scan. The sensor comes with a mounting screw if you want to put it on a wall, but the sensor can sit on a shelf or table and is small enough to be unobtrusive. The only drawback for me is that, personally, I really think a sensor should be included with the thermostat from the get go instead of being a separate purchase, like comparable Ecobee products.

    I bought this temperature sensor to help the Nest Learning Thermostat E control the AC temperature. The problem is most thermostats are installed in the hallway and most hallways don't have vents. This means that the temperature in the hallway is almost always going to be warmer than a bedroom, office, etc. The problem that we had was in the bedrooms it would be hot, so I'd set the thermostat to 74 degrees which read its temp from the hallway, so the bedrooms which are smaller and all have AC vents would get freezing cold. THE SOLUTION This Temperature sensor. I bought one an placed it one of the bedrooms. Now the temperature is being read from the bedroom, and to my amazement, the bedrooms read up to 4 degrees cooler. Now when I set the temp it reads from the smaller rooms, now the temperature in all the bedrooms and the office are pleasant. The only rooms that require the temp to be tweaked is our large living room. That's a simple fix though I can lower the temperature using my phone, Amazon echo or my smartwatch when were in the living room. Install could not have been simpler, open the box, take out the sensor, pull the plastic tab that connects the battery, open the nest app it finds the sensor. THAT'S IT. Well worth the money in power savings and comfort.

    I have (1) thermostat in the center of my house and suffer from varying room temperatures. Our bedroom can go down to 66 degrees at night when our thermostat says 70 degrees. I just recently purchased a Nest 3rd generation thermostat along with (3) Nest temperature sensors. Last night was the first night using it and our bedroom stayed at 70 degrees! You just go into the settings and tap which sensor you want to go off of and the temperature you want it set at! So easy! I would highly recommend these thermostat sensors to anyone who owns the Nest 3rd generation thermostat and suffers from various temperatures in different rooms! I understand that previous generations are not compatible with this...However, I don't think that it's fair to bash the review on these sensors because it's not a surprise that they don't work on previous generations. Nest states that they only work on 3rd generation thermostats. Does it stink? Yes, and I hope they can come out with something in the future for previous generation owners. But, please do not rate this product bad because of this.

    Our master bedroom is unfortunately built over the garage of our house. It’s not a big deal in the winter. However in the summer this causes it to be scorching. We’ve seen it reach 80 degrees before. To get it anywhere near comfortable we’d have to set the a/c to a much lower temperature than the main floor and wait at least an hour to cool down. Life being life however we frequently forgot to do that until we were getting ready to go to sleep. Which caused uncomfortable nights trying to get to sleep. In a last ditch desperate effort we bought the sensor to hopefully take care of that annoying little chore. And we have to say it works amazing. We can choose when the temperature defaults to the sensor and program in what time we want it to cool down through the Nest Thermostat calendar. You can also manually change between the thermostat and sensors as you please. The only real downside to this is you have a time table you have to pick from for the programmable sensor time ex: 7am - 11am. Which compared to the complete control you have with everything else seems like an oversight. All in all I would give it a 9/10 and will probably be purchasing another for our finished basement come winter.

    I just found out these were available and had to have one today! I love how small the device is and it's 2 year battery life. We've struggled with winter temps that always makes us too hot or too cold due to the thermostat reading temperatures in our open living room. Very simple setup as well- just unscrew the back plate and take a QR pic or id# to register it. Install the back, then you're good to go. It can be left on a counter or comes with a screw to mount it as desired. I just think there needs to be a software upgrade that would allow a time frame of when to use the remote sensor and main thermostat. We only use it for when we sleep at night for a more accurate reading. I highly recommend this product to anyone with a Nest that has a oddly cold or hot room as this could solve your issue.

    Excellent Add-On Temperature Sensor for NEST

    I've been a fan of NEST thermostats for many years and recently added the simple NEST Temperature Sensor to my home's HVAC control system. I noticed that the upper floor of my home never seemed to reach the set point temperature of the NEST Thermostat, thus added the temperature sensor to my master bedroom. Wow - so easy and a great add-on. It basically helps me balance out the control temp in the house by averaging the temps it sees at the main thermostat downstairs and the add-on temperature sensor upstairs. My wife is really impressed too. Gives her the comfort knowing that the tstat will keep cooling system going in the summer time a little longer than before, until the set point is reached upstairs as well. This is a no-brainer to add the NEST Temperature Sensor(s) to any home; especially if you have a multi-floor home or areas that are traditionally much cooler or hotter than others. I definitely recommend this little, affordable temperature to any NEST controlled home. Great Product NEST engineers !

    Limited schedule options

    The sensor is in a manufactured home in the main bedroom approximately 35 feet horizontally from the Nest thermostat in the living room and I get the message "weak connection to the thermostat" in the Nest app. I'd assume the range would be reduced even more in a larger house or multi level dwelling with more walls and ceilings to go thru. The message comes and goes and there is almost a direct line of sight to the thermostat when the bedroom door is open. There is also no scheduling option for the sensor. You manually change it to the sensor and it will revert back to the main Nest at the next time you have a temperature change set on the schedule. So you can't tell it to use the sensor at let's say midnight when you may go to bed and then back to the Nest in the living room at 8am when you'd get up. It half works because you'd manually tell the Nest to use the sensor in the app or the Nest and it would then automatically change to the Nest in the living room at the next scheduled temperature change. You can't do a daily or weekly scheduling between the sensor and Nest.

    I like that i can prioritize my bedroom over the family room where my Nest is located. i this would be 5 star if i could customize more like the time to prioritize a room. my Nest as learned the times and temps i like. if i could make evening or night the times i typically go to bed instead of the preset. Also the setup and walk away is a little misleading. while the sensor is very small and discreet, dont put it next to a device or appliance that produces too much heat. ie: a tv or lamp that you run often. in just the few hours i have had mine i had to move it from behind the tv dresser( where my wife liked it. completely out of site). certain areas may "trap" heat and throw off the rest of the rooms comfort. it might seem obvious but in my case the best furniture also has other items that can change temp enough to confuse a sensor. otherwise i love it! i have been holding out switching from Nest to Ecobee for this!

    I purchased 2 of these sensors with a Nest Gen 3 Learning Thermostat, thinking I would be able to have my 3-story home heated/cooled based on a combination of the 3 units. Unfortunately, I didn't do all of my homework before buying the sensors, and I late found out that the thermostat can only heat/cool the house based on the sensing of only one unit at a time. So, my themostat is on my main floor, and I have a sensor in my basement, and one on the second floor. I can only run my heater/AC based on one of the sensors. Like in the winter, if my basement is colder, I would set my system to heat based on the basement sensor or thermostat on the main floor. And in the summer, I would cool my home based based on the second floor sensor or thermostat on the main floor. But it won't equalize my temperatures in the entire home based on the readings of all 3.

    Wow! Nest just keeps impressing me! I loved my Nest 3rd Generation Thermostat and other products already but we have a couple rooms that are used frequently and are hard to keep the correct temp. This product does the trick. It was installed in a very short time and I can control them (I purchased three for my home and may get one or two more) with my iPhone or iPad. It could’ be simpler to operate. And you have the option to put them up on the wall with the provided screws OR you can simply place the cute little Nest on a shelf or a dresser wherever you like. It’s a little guy only about the size if a hockey puck approximately. It fits in the palm of your hand with room to spare. It’s amazing! My home office is COMFORTABLE to work in all day. I can save money and lower the temp in THAT room. You can set timers for each device if you wish. Trust me. This is a game changer in our lives!

    I've been using Nest products for years, starting with their original Learning Thermostat, and the only issue I've ever had with them is lack of multi-point sensors. Competitors have had them for some time, and the temperature variation in my house is significant enough that I was considering switching smart thermostats solely because of that lack. Glad I didn't; the addition of these sensors solved my problem, and their design, efficiency, build quality and ease of use are everything I've come to expect from Nest. A good system is now an excellent one. The only thing that would make it better is if the sensors (or some combination of Nest devices) could automatically tell what room you are in and adjust accordingly; currently you have tell it which sensor to use (either manually or via a schedule.) This, however, is a minor quibble at best, and in no way detracts from the usefulness of the system.

    I recently sampled the Nest 3rd Gen thermostat and was forced to purchase this sensor due to the extreme temperature variance from the thermostat which was located in my hallway. the temp was off by 5+ degrees and still cold in the house. This sensor did indeed fix the variance and get the house heated properly. But after a month of use, I decided to return everything and go back to my Sensi thermostat. I found the Nest difficult to get up and working properly, which took about two weeks of fiddling with variance settings. Prior to getting correct settings, heat would stop working on multiple occasions, unit would run nonstop for hours requiring a reboot. I missed multiple features from my Sensi unit which has builtin temp. variance adjustment. I also can create multiple schedules which the Nest only has one schedule.

    it keeps you upgrading... In truth this is not one of those items you regret upgrading ... You have to have Nest Gen 3 to use these sensor, so hence the upgrading remark... But so Kool and worth it because you get more then one isolated and single temp. And instead get multiple zones of specified custom heating and cooling to the room you need. Moreover knowing what the true Temp of your basement, bedroom and/or baby room is extremal valuable.. Because a single hall way Nest is not as effective in my opinion.. Some how I fell this item is great for a family of empty nester or a family with a single baby and feel it would be some work for accompany a bigger family.. But I'm sure it can be done because a one thermostat house is just as tricky because some one is always hot and some one is always cold... but I'm sure this item will help with that.

    I have owned this product for around two months now and have been able to see its full potential. My wife and I have a two story house with one heat pump and a Nest thermostat. Because of the placement of the Nest downstairs, the upstairs temperature is either too hot or too cold so that is where this temperature sensor comes into play. The sensor connects very easy with the nest thermostat and as long as your wifi signal is good it updates frequently. It does come with a screw to mount to the wall or it can be placed on a table. The biggest issue I have had is the temperature doesn't quite match up to what it really is, normally it is off by 1-2 degrees but this is still far better than what it was before.

    I purchased two nest thermostats and really liked the idea of remote sensors. The sensors are electronic thermometers that can be placed at remote locations to both tell the nest the temperature at sites removed from the thermostat and to control the heating and cooling, such that the target temperature needs to be found at the remote location. In our house, the thermostats are located in the hallways and they always seem to over heat and over cool the bedrooms. We can use the sensors in the bedrooms as the target control point for the heating and cooling of the house. They were easy to install and to link to the thermostats. I purchased a sensor with the two thermostats (and then 3 more sensors at a later date). They have been working great. I would purchase again.
