SmartSensor (2-Pack)

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

I really like the Ecobee ecosystem, and these don’t disappoint for what they are. They connect seamlessly and for the most part work as functioned when paired with the thermostat. My only gripe is that “presence sensing” really isn’t that functional, particularly if there isn’t movement in the room (such as sitting and watching TV). Nevertheless, would buy again and appreciate that you can automate based on these sensors.

Worked as advertised. Great product

Fresh out of the package easy setup. Better response from Ecobee with more inputs.
