I've had this product for years, and have been running three sensors for most of that time. My Ecobee came with one sensor and I added this 2-pack to get me to three. It is very useful to have sensors and be able to have the Ecobee use a sensor in combination or as the primary temperature source for my heating and cooling settings.

These smart sensors are a great addition to the house to get a better understanding of how you floor vents heat and cool a room. At a glance though the app you can compare each room after a heating cycle to see which ones are hotter than the others and maybe adjust some dampeners to keep temperatures consistent throughout the house. Not only that but the addition of these to make the thermostat even smarter by using specific sensors based on comfort settings is super great. Giving them a 3 star on performance as i feel i change the batteries a little too often

I have somewhat large temperature discrepancies between some rooms. During the winter while some of them are very cold, some others areas are very hot; the opposite happens during warmer days. The sensors allow my thermostat to average the temperature in these areas so all of them have about an average temperature and helps saving on electricity charges. My only drawback is they can be a pain when they disconnect due to interference and they are very expensive.

I've had the 2 pack sensors for a few months and it has helped me get a better average temp reading among three rooms. I had cold spots in two rooms but the two sensors have helped me even out the heating issue I had.

I've had this product installed for 7 days and I can say remote sensors are a game changer. There's are very simple to pair, name and place. Setup in the thermostat/app are really simple. Choose when the sensor is to participate in the heating/cooling (while at home/at night,/away) and that's it.

I've had this system for about one week. I'm very happy with the system. I would recommend this system to every one.
