SmartSensor 2 Pack, White

Good, but expensive.

These have really helped my system. My thermostat is on a wall that is also the return duck going up into the attic. Because of this I have never had correct reading from the thermostat, and I have had two different ones. This one you can change the reading by setting a correction value but this still did not help me. In warmer temps it needed one setting and another in cooler. It was annoying. I got these and placed one in the kitchen and the other in the living room. What I found they do is communicate with the thermostat and they create an average temperature for the house. This has made the readings much more consistent and accurate. I am much happier now and was able to remove the temperature correction from the thermostat. They were extremely easy to set up. The are also small and do not stand out in the room. I have not had any issues with them not picking us up and detect motion well.

I did not realize it did not reach my thermostat from my bedroom in a two story house. The one in the living room is ok and a great help. I wish I would have known before I purchased. This is a fantastic product, but depending on square footage it may be difficult.

These work very well with Ecobee thermostat . They help reduce needless equipment running when rooms are unoccupied. Work really well for central air in our home as the downstairs can get cool much faster and the system doesn’t run needlessly when the upstairs is unoccupied most of the day. Reliability has been excellent.

I have a 2-story 2500 sq. ft. house and my thermostat is downstairs. I have the "Lite" version of the Ecobee thermostats and it was able to sense both sensors even though I activated them from my office upstairs. Easy peasy. They read the temperature perfectly and look aesthetically pleasing, however they are small enough that they could easily get lost or the kid could accidentally play with it. Keep them in a spot that's difficult to reach.

Remember you are buying a tool to average temperatures so something like a cold addition or bedroom matter in the thermostat math mix, or a fireplace doesn't shut off your thermostat, there isn't much else its good for. If you need that function get it, we're happy with ours. Was harder to connect than it should have been..still works fine after you get it connected. It does improve scheduling insight and help you see where your house is struggling to keep temps, or perhaps where its not struggling such as a warm bedroom upstairs. Delivers a cool modern function for a reasonable price, worthwhile.
