Nest Temperature Sensor Review | Should You Buy the Nest Sensor?


There’s a great update for nest owners. With the latest Nest Temperature Sensor, you can use and take the temperature recording from another spot in your place!

This latest sensor is wireless, small, and battery-powered. It is approximately 2 inches in diameter. You can use this device with either the Nest  3rd Generation Learning thermostat or the Nest Thermostat E. It is sold individually, however, you can simply get it from the places where Nest products are available. 

Also, you can have around 6 sensors per Nest thermostat including up to a total of 18 in a residence.

Things You Can Perform With The Latest Nest Temperature Sensor

Here are the things you can try out with the new Nest Temperature Sensor-

  • You can take temperature recording from a different spot across your room, apart from the place your thermostat is established.
  • According to your schedule, you can switch the temperature reading by using the sensor and thermostat’s temperature.
  • You can also control the temperature of different parts of your residence through the app.

However, this idea isn’t unique. For years now, Ecobee has also had a combination of a motion sensor and room temperature with their thermostat. Nevertheless, this is a fresh addition to the Nest list.

Nest Temperature Sensor Review: A Quick Overview 

  • It operates with the 3rd generation Nest Learning Thermostat and Nest Thermostat E hardware.
  • It takes about minutes to set up. You can do this by scanning the QR code at the back.
  • Wireless
  • It uses a CR2 3V Lithium battery, and along with that, it is expected to have a 2-year battery lifetime.
  • Connects with your Nest thermostat through Bluetooth LE. So, even if your Wi-Fi is down, it will keep working.
  • You can get it either in 3-pack or 1-pack.
  • You can program it with some restrictions.
  • The maximum range from the parent thermostat is 50-foot.
  • Can add around 6 sensors per device and a total of 18 sensors in a residence.
  • It is small and modest in size. It can easily be put on a shelf or somewhere else.

How Is The Nest Thermostat Sensor Beneficially For Different People?

  1. It is beneficial for families with multi-story or large homes.
  2. If the thermostat is located in a particularly chilly or sunny location in the residence, then it is beneficial for such homes.
  3. For the people who mostly spend their time in one room and don’t bother about the other parts of the residence.
  4. For the people, who can’t move their current thermostat to somewhere else to get an accurate record.

This sensor is for you if you simply dislike the temperature recording that your Nest is getting from its current location. It can be either too cold, too hot, or something else. You can simply place the sensor in the room you like, and you will get the reading instead. It’s like your thermostat is moving without actually moving.

Functions It Won’t Perform

It will not redirect cooling or heating

The nest Thermostat Sensor is not like any other thermostat sensor system. It is not a substitute for a dual-zone HVAC system. This means it will not redirect cooling or heating. So, in case you want to use this sensor for making a really cold room, slightly warm, then you can’t have it without actually roasting the rest of your place. It will not stop your HVAC system from making the other rooms hotter.

If you know that warming up that always-cold room will lead to making the other parts of your house uncomfortably heated, then the sensor is not going to fix that. However, there are other methods to fix that issue. 

You can go for installing closing vents somewhere in your house, and you can also go for heat blocking curtains in the rooms which are always warm.

The sensor is not a movement detector

This sensor is built in a way to read the temperature, not movement/motion, unlike the Ecobee’s sensor, which can detect both temperature and motion.

This is sort of a missed chance for the nest users. As the nest thermostat works with sensors along with the location of your smartphone to conclude if you’re home or not. This feature of the thermostat is identified as Home/Away Assist. 

However, if your thermostat is in some corners, it may not detect that you’re home. This is one of the common complaints from Nest users. And it is not also included in the sensor.

Restricted scheduling

Even though Nest allows you to make a schedule that is based on the sensor’s temperature recording, there are some predetermined schedule sections that you have to use. These are

  • “morning” is 7-11 am
  • “afternoon” is 11am-4pm
  • “evening” is 4 pm-9 pm
  • “night” is 9 pm to 7 am

If these blocks suit your schedule then it is awesome. However, for those

whose schedule doesn’t fit within these blocks, it might seem restricting. We hope in a future update, Nest adds more satisfying granularity to the schedule feature.

It doesn’t record sensors in a bundle

The nest sensor just notices the temperature that it should be recording for a particular time and then it performs accordingly. So, if you’re hoping that the nest thermostat checks up on every sensor, and if one of them drops below a specific temperature, it will start warming up. No, it doesn’t work like that.

However, it is an important feature, hopefully, they will include this in a coming update.

It doesn’t regulate humidity or air quality

If you’re expecting a strong sensory experience, then it might disappoint you.

Why Some Part Of Your House Colder or Hotter Than Rest?

It is rarely seen that houses have the same temperature everywhere. Your place might also have a room which is always warmer or colder than the other. This is because of factors such as window quality and size, exposure (east, north, etc), building materials, your HVAC system, and the position of your thermostat itself.

Most of the time, the thermostat reads your place’s temperature from the spot it is located, but for the homes, where there is a lot of variance in temperature, it isn’t ideal.

However, if you have a house with variations in temperature, here are few things that you can do-

  • You can get thermal curtains for the rooms which are always warm and keep them shut. This way, the room will not become uncomfortably warm when you heat up for the room that is always cold.
  • You can also experiment with the closing vents. It will help in directing the heat to the room that is always chilly.
  • If you don’t use some of your rooms frequently, you can shut the doors.
  • Also, you can go for a space heater for the coldest room.

Ecobee Sensors vs. Nest Sensors

So, if we’ve to compare the Nest and Ecobee sensors, then the realm just leveled up. As the Ecobee’s sensor comes with a lot of defining yet unique features, they have won this race. As they have an inbuilt motion detector, where the nest sensor is yet to have one.

Here’s a comparison table, so that it’ll be easy for you

Features Nest Sensors  Ecobee Sensor
Motion Detector No Yes
Bundled With Thermostat No  Yes
User-replaceable Battery Yes Yes
Schedule Feature  Yes (but restricted) Yes
The maximum quantity of sensor supported 6 per thermostat 50 per thermostat

(but that’s too much, right?

As I’ve mentioned above, Ecobee is still at the top. Along with that, it also has an inbuilt Alexa feature, which makes it more convenient. Additionally, there is a motion detector along with the room temperature sensor.

However, if you have the integrated products of the Nest family such as Nest cameras, Nest protects, Hello doorbell, or the smoke detector, then without any doubt Nest thermostat is the best pick for you. As it has a better ability to connect with the sensors as well as the other product.
