Bests & Worsts Reviews from Amazon

Many people have reported that the batteries in these new “Smart Sensors” die quickly. The batteries in the two sensors I purchased died within 3 days, and the sensors disconnected from the paired thermostat. Many people have reported this happening with the new version of the Ecobee Smart Sensor. The manufacturer diagnosed my Smart Sensors as defective after I reported this to Ecobee, but they are unable to ship replacements under the warranty right now.
