How Do Ecobee Sensors Work?

Have you ever wondered how those little ecobee sensors work? Well, wonder no more! In this blog post, we’ll take a closer look at how ecobee remote sensors and smart sensors work, and how you can use them to save energy and money.

Introduction to Ecobee Smart Sensors

Ecobee sensors, known as Ecobee Smart Sensor are devices that are designed to be placed in strategic locations around your home in order to better monitor the temperature and occupancy of a room. By doing so, they can provide your ecobee thermostat with more accurate data, which can in turn lead to improved energy efficiency and comfort.

There are two types of ecobee sensors: room sensors and remote sensors. Room sensors are designed to be placed on a wall or shelf in a particular room, while remote sensors can be placed anywhere else in the home (e.g. in hallways, basements, etc.). Both types of sensors come with a mounting bracket and hardware for easy installation.

In addition to temperature and occupancy sensing, ecobee sensors also feature humidity sensing (on select models). This allows them to further improve the accuracy of your thermostat’s temperature readings, as well as optimize its performance for specific climates.

How do ecobee sensors work?

The ecobee3 lite and ecobee4 come with one remote sensor, but you can buy extras to place around your home. The sensors detect both occupancy and temperature. They use infrared to detect motion in a room, and they measure temperature using a silicon band element.

The ecobee3 lite and ecobee4 can hold up to 32 sensors. The app will automatically place the sensor that detects the most motion in the room you designate as the “Home” or “Away” room. The other sensors will be placed in “Away” mode.

The benefits of using ecobee Smart Sensors

Ecobee sensors are designed to save you energy and money by making your home more comfortable. By monitoring temperature, humidity, and occupancy, ecobee sensors can adjust your thermostat settings to provide the perfect indoor environment while maximizing energy savings.

There are a number of benefits to using ecobee sensors, including:

  • Improved comfort – by ensuring that your home is the perfect temperature, you’ll be more comfortable year-round.
  • Energy savings – by automatically adjusting your thermostat settings based on occupancy and temperature, ecobee sensors can help you save money on your energy bills.
  • Peace of mind – with ecobee sensors, you’ll never have to wonder if your home is comfortable or not – you can relax knowing that your thermostat is working to keep things just the way you like them.

How to install ecobee sensors

In this guide, we’ll show you how to install your ecobee3 lite with built-in 3rd gen sensors. We’ll also go over some tips on where to place your sensors for optimal results.

If you purchased an ecobee3 lite without built-in 3rd gen sensors, you’ll need to purchase them separately. We recommend purchasing at least two for best results.

To begin, find a level spot on your wall where you’d like to install your ecobee3 lite. Once you’ve found the perfect spot, use the included drill bit to make a pilot hole. Be sure not to drill too deeply, as you don’t want to damage any wiring that may be behind the wall.

Next, insert the included wall plate anchors into the pilot hole. Gently tap them into place with a hammer until they’re flush with the wall surface.

Now it’s time to install the provided wall plate. Start by threading the exposed end of the wire through the center of the plate. Once the wire is in place, screw the plate onto the wall anchors until it’s snug against the surface of the wall.

Finally, gently push your ecobee3 lite onto the day-to-day and slide it up until it clicks into place. That’s it! Your ecobee3 lite with built-in 3rd gen sensors is now installed and ready to use.

How to use ecobee Smart sensors

The ecobee sensor is designed to work with the ecobee3 and ecobee4 smart thermostats. The sensor can be placed anywhere in your home and will adjust the temperature based on your needs.

To use the sensor, first, download the ecobee app and follow the instructions to create an account. Once you have an account, you can add new devices, including the ecobee sensor.

Next, install the battery in the sensor and wait a few moments for it to connect to your thermostat. Once it is connected, you can place it in any room in your home. The ideal location is somewhere where people typically congregate, such as a living room or kitchen.

The sensor will automatically begin monitoring the temperature and occupancy of the room. It will adjust the temperature accordingly to ensure that everyone in the house is comfortable.

FAQs about ecobee sensors

Can one sensor do the job of many?

Yes. A single ecobee sensor can be used to sense both temperature and occupancy. However, for optimal temperature accuracy and comfort, we recommend using multiple sensors throughout your home.

What is the range of the ecobee sensors?

The range of the ecobee sensors is approximately 45 feet, provided there are no major obstacles between the sensor and the thermostat.


To sum it up, ecobee sensors work by communicating with the ecobee3 thermostat. The sensors detect changes in temperature and occupancy, and relay that information back to the thermostat. This allows the ecobee3 to make more informed decisions about when to heat or cool your home, resulting in increased comfort and energy savings.
