Customer Ratings & Reviews

Small and easy to hide. Occassional connectivity issues (5% of the time) otherwise pretty accurate as verified by another temperature gauge.

small, nice looking, easy to use, doing exactly what we needed

I wish the ecobee thermostat didnt average the temps from the sensors and it just ran off of the thermostat sensor. I have a couple of these through the house because we were remodeling and i just didnt want anything to be forgetton amd freeze through the winter. They worked well but i realised quickly thay the thermostat ran off an average temp and i was just wanting to use them as temp sensors. They work well though.

Beautiful streamlined modern design. Great high quality packaging. Small footprint. Seems accurate to me. Links to Ecobee Smart Thermostat like a dream.

Sleek thermocool and temperature detector. Worked as expected.

Easy setup. Works great! Highly recommend for Ecobee

They work as advertised and the battery life on them is great, but the only reason I can't give it 5 stars is because the price is SO high. It's almost as much as the Thermostat itself...

Works great to regulate thermostat settings for different times in different rooms. Upstairs registers warmer throughout each season, so these help maintain a comfortable temp year round.

Paired with the thermostat easily. Worked as described.

Great product, easy to connect , works as promised. Very pleased with this purchase, item was $10.00 cheaper at Best Buy than at Amazon and was waiting for me in the locker that same day!

These things just opened my mind to all the things possible these days! Automatically senses which rooms are occupied and can average the temperature between all sensors or just occupied rooms for more even heating of your place! And I just found out about those automatic smart air vents that work with Ecobee, amazing! Couldn't be easier to install!

The additional sensors proved to work great during the recent heat wave, working to balance the home temperature where we are in the house. Considering the end of day heat in some rooms the added sensors have worked great. We now have a total of 6.

After having an Ecobee 4 for awhile, we wanted to see the whole home, instead of just the room where the thermostat is and the room where the included sensor is. These do that, and they’re very easy to set up and pair. Only took about 5-10 minutes to set up and they’ve worked ever since.

Our ecobee is saving us money and these additional SmartSensors help keep rooms that are in use at the right temps, and those not in use, at more economical settings. They are super easy to install and can be set nearly out of sight on a shelf, or even hung in the corner of the room.

While I was quite hopeful these little smart sensors would be a good fit for use as a type of motion detector, for intrusion detection, I think they are better off for what they seem to be originally geared towards which is as an accessory for the ecobee Smart Thermostat; when time isn't of the essence. After quite some time playing around with them, I find that the detection on this is very intermittent and inconsistent. I'm used to working with devices that would alert you to an intruder as many times as you cross their path. These devices do not do that. In this case, it seems that it only activates or "wakes up" every so often and this is likely due to the need to conserve power. The battery is rated to last for multiple years and since it is nothing more than a coin cell battery, it could not constantly be on and detecting movements and still last for this period of time. Thus why the detection of someone is intermittent. As for consistency, I've set it off sometimes, and sometimes not. My large (85lb) dog sets it off sometimes and not others. My 15lb dog sometimes has not set it off so far. I realize an intruder might be 85lbs, so it is necessary to go off for that, but it doesn't always happen this way. What does this mean for you? If an intruder happens to come into your home by breaking a window for example, you would have to hope that it was at the time the detector would notice and generate an alert. The environmental features of this sensor are only available if paired to the ecobee smart thermostat, so they cannot be used for temperature monitoring or temperature alerts if you don't have the ecobee thermostat. I would not recommend this for the purpose it is being marketed for, because if you count on this as an intruder detection device, it could be some time before it notices someone rummaging through your things, if it notices at all (such as if you left the area it is placed within).

Integrated perfectly with my Ecobee Smart Thermostat. A little confusing on how to make the best use of the sensors in relation to the thermostat settings, but it is nice to be able to specify which room drives the temperature the thermostat will maintain. I have the sensor in the family room be the driver during the day and the one in the bedroom be the determining factor at night. My only complaint is the extra sensors seem a little expensive to me for what you get.

Seems to capture the temperature accurately. It has greatly improved our sleeping situation now. You don’t have to keep changing the temperature and adjusting the AC

I can’t imagine having an ecobee without these sensors. They let me control what rooms to focus on for comfort. At night, the thermostat is only concerned with my bedroom. During the day, whole house thanks to these little guys. Since they are HomeKit compatible, they can act as motion sensors for the rest of my smart devices.

I had one sensor just wanted to know the temp in other places in the house. Does a great job at that. Just make sure you place them appropriately. Out of direct sun, or direct airflow of HVAC as well as height placement. Too low on shelf will register cooler than it really is and same as too high *the heat of the room rises). I try to keep it as close to the thermostat height to be consistent. Only wish it would include humidity levels.

Great product. Works as described with no issues. A bit expensive.
