Questions & Answers


Can i set a sensor to automatically monitor and set the temperature of a specific room, e.g. master bedroom for specific times, such as from 9:00 p.m.

Asked by Nevinator June 18, 2020

Kind of. It takes the average of sensors participating and follows the regular schedule. So if you wanted to monitor just one room, you would have to turn off participation of all other sensors during that period, which you can do.

Asked by JPVOLS4 June 14, 2020

Hi there! ecobee SmartSensor is desiged to work with a single CR-2477 battery. They can be readily found in most hardware stores as well as from online retailers. We do not recommend using a different type of battery.

Will it work with the older ecobee 3 thermostat?

Asked by Charlie June 2, 2020

Absolutely! Our all-new ecobee SmartSensor works with all ecobee smart thermostats.

Asked by joepublic December 20, 2019

Not really sure of the method, but I can verify that it CANNOT tell that a room is occupied when everyone is sleeping soundly.

What type of battery is used? Is it proprietary or is it a AA or AAA?

Asked by Pete July 27, 2019

Uses CR2032 that can be found in all stores that sell batteries.

Quality :
Included with the sensors (2 in each pack), instruction manual, plastic stands, and wall mounting hardware. I recently got two Ecobee 3 lite’s (which don’t include sensors) and an Ecobee 4 that has one but I wanted a bit more coverage on the different floors of my homes, because without the sensors it is just a regular wi-fi thermostat. The Ecobee thermostat’s main advantage is its ability to sense temperatures in various rooms with the extra sensors. So, I order 4 room sensors of these to add to the 3-lites on the different floors. After some confusion with CS on how many sets are included (there are supposed to be two sets of 2), I finally received the 4 sensors. As another reviewer has said, there is some confusion with the Amazon page and for some reason, they can’t seem to figure out something priced per set, means more than one set (or pack) of sensors. The sensors are very easy to install as you simply hold near the thermostat, pull the plastic battery tab and the thermostat automatically recognize it and asks to add it. You then select a name for it or give it its own unique name. It starts detecting the temperature immediately. I paired each sensor to different thermostats. Just hold the sensor next to the thermostat that you want to pair it to. The sensors do not interfere with one another. One small issue with the sensor is that it may read too warm initially, if you are holding it too long in your hand, making for an inaccurate average temp reading. Luckily, the sensor quickly corrects itself, but you may have your A/C come on briefly because of it. The sensor is a simple square design with a logo and can be put on the wall or on the included stand. I do kind of wish the stand had a lock mechanism built in, although I haven’t really had any issue with the sensor staying on the stand. It is more for my being sure it will not fall off where it is. My main complaint with the sensors are the lack of any type of low battery indicator. There is nothing on the sensors themselves and the Ecobee app does not tell you when the battery is low or dead. It may be some period of time before you notice it is time to change the battery, so it is an important function that should be added, with maybe a small led low battery indicator, along with the app letting you know as well. Each sensor requires a CR2032 battery when they need to be replaced. Just pop off the battery cover on the back and replace the battery. Considering these are low power device, the batteries should last several months or longer. So far, they are working well at detecting motion and temperature. It remains to be seen though, the durability of the sensors. According to the specifications, the sensors have a 120-degree field of view and can detect motion up to 15 feet using an IR sensor. The sensors seem to detect occupancy for a period of time after the room becomes occupied. Now these sensors, won’t create additional zones in your home as that is dependent on the system you have in your house, but will help create an average temperature between the various sensors to help heat or cool areas of the house that are occupied. You can manually adjust your vents to also aid in heating and cooling the areas of your home. For the sensors to be the most effective, it helps to enable the follow me and smart home settings in the sensor portion of the app. The sensors have a good 3-year warranty. I do think the sensors are a bit pricy for the pair. 4 stars

Total game changer! My home would be 73 where the thermostat was, yet 80 in my kitchen. With the new thermostat in the same location the sensors pick up the temperature from the thermostat, living room(sensor), and kitchen (sensor) then averages them out to start the AC sooner to keep the whole house cool.

That's not the experience we want you to have! Please send an email to with your SmartSensor serial numbers. Happy to help make this right! ecobee

I really wasn’t sure if I needed these or not, but figured that if I was going to get the most out of my Ecobee I would try them in different rooms. Once I determined that you can ‘turn on and off’ sensors, including the main Ecobee, then the full potential dawned on me. Now I am not heating or cooling just where the Ecobee is. This may not seem like a big deal, but I can see where the system used to run based off the temperature at that thermostat and now it is not. Bottom line: yes the sensors placed in the rooms you live in and want to control at various times of the day makes sense.
