I’ve had the Nest Room Sensor for installed in my home for several months now and can report back that it’s been a great investment to help regulate the comfort of my home. The Nest Room Sensor acts as a remote temperature sensor that can communicate with the Nest Thermostat to help better control the temperature in individual rooms of your home.

The Nest Room Sensors launched in 2018 and work with both the Nest Thermostat Gen 3 & the Nest E Thermostat. If you have an older generation 1 or 2 nest thermostat the Nest Room Sensors will not work with your older nest thermostat.

What Is The Nest Room Sensor?

The Nest Room sensor directly connects to your Nest Thermostat via nest’s special wifi network and remotely reports the temperature to help you manage the temperature in other rooms in your house using the Nest Room Sensor.

So if your Nest Thermostat is in your living room you could locate your Nest Room Sensor in your bedroom to monitor the temperatures are in different parts of your house, condo or apartment.

What’s even better than the Nest Room Sensors remote temperature sensing capability is that you can set your Nest Thermostat to maintain the temperature you choose at the location where the Nest Room Sensor is located, giving you exact control of the temperature of any room in your house.

If you place a Nest Room Sensor in your bedroom, you could set your Nest Thermostat to maintain 70 degrees in your bedroom, rather than 70 degrees in your living room. No house has uniform heating and cooling and the Nest Room Sensor helps to solve this problem to optimize your comfort in each room.

The Nest Room Sensor information shows up underneath the Nest Thermostat information. You can toggle between rooms you would like to control the temperature for.

Nest Room Sensor: Best Uses

We live in a multi-floor house and every year when we change from heating to cooling or cooling to heating I adjust the floor vents and dampers in my house to make the heating system more efficient and the house more comfortable.

Heat rises, so in winter I turn down some of the vent’s upstairs because the heated air ends up making its way to the upstairs which is typically hotter than the floors below.

In the summer I open up the vents in the upstairs and close some of the downstairs vents because cold air sinks, and this seems to help balance out the heating, cooling and comfort in my home.

When I do it I typically also replace my air filters to keep the furnace running smoothly and increase its lifespan. It takes less than 10 minutes for me to do the entire home but makes a huge difference in comfort and energy efficiency

I used to continually adjust the vents in my house throughout year, but with the Nest Room Sensors I have been able to find the parts of my house that heat and cool differently and it has allowed me to more precisely dial in my heating and cooling system by opening and closing vents to get the home as close to a uniform temperature as possible.

My favorite part of using the Nest Room Sensors is using them to set the exact temperature in our master bedroom that I know I will be comfortable at. I typically sleep hot, and with our thermostat located downstairs before we had the Nest Room Sensors installed I would wake up typically to hot and rarely to cold. In the summer the master bedroom upstairs would be quite a bit hotter because it’s directly under the roof where as the living room is on the floor below meaning the AC wouldn’t kick on until the temperature was raised in the living room at which point it would feel like our master bedroom was sweltering. Now when I sleep I can set the temperature to an exact temperature in our master bedroom and it will stay there all night. It has greatly improved my comfort and quality of sleep since having the Nest Room Sensor installed.

I also have a Nest Room Sensor placed in our garage because I have hose connection in the garage and during the winter want to monitor it to make sure that it doesn’t freeze. You could use the Nest Room Temperature sensor to monitor the indoor temperature in a basement or where exterior wall plumbing is located to prevent your pipes from freezing. I have heard of people placing them under kitchen sinks in older houses with less insulation so they can monitor the temperatures to prevent pipe from bursting during extended cold spells.

On the converse you could also use a Nest Room Sensor in your attic to monitor the temperature of your attic during the summer, and when to turn on an attic ventilation system if your house is equipped with one.

I have one of mine sitting behind one of our sonos speakers and you can’t see the small profile of the Nest Room Sensor behind the speaker.

Beyond detecting temperature and allowing you to control the temperature in a room where the Nest Room sensor is placed it will also let you set schedules for specific temperature sensors in specific rooms so you can control the temperature in the rooms you are using the most in your house.

In the screenshot below from the Nest app is an example of the temperature sensor scheduling screen. You can pick different sensors that you would like to be used control the temperature in your house throughout the day. For our house I use the sensor schedule to control the temperature in our master bedroom in the evening and at night before going to bed.

Nest Room Sensor Review: What You Should Know

The Nest Room Sensors will tell you the temperature wherever you place it and allow you to set that room to a particular temperature, but it can’t change the differences in how your house heats and cools. If your house was designed with too many vents or too few vents in a particular room, or with not enough insulation the Nest Room Sensors can’t solve that physical problem for you.

But the Nest Room Sensors can help heat and cool the parts of your house you are using to a more comfortable and consistent temperature. If your Nest Thermostat is located on the 1st Floor and your bedrooms are on the second floor. Placing a Nest Room Sensor on the second floor can help you stay more comfortable while sleeping.

Below we have some tips on how to better heat and cool your house if it does heat and cool unevenly.

The Nest Room Sensor can help as we’ve describe above but you can also do the following to help make the heating and cooling of your house more uniform.

Adjust the vents in each room in your house, to properly control the airflow.
Adjust the dampers located on the ductwork, to control the airflow. Ductwork dampers are typically located near your furnace or in your basement in an accessible location. On the side of the ductwork they typically look like small metal lever that you can adjust to either open or closed.
You can add a smart vent like the Keen System, or a temperature controlled booster fan to better regulate the temperature throughout your home.
