Hello there, KEVIN. Thanks for sharing your feedback about your Nest Temperature Sensor. We're sorry to hear that your experience with the device didn't meet your expectations. Your Nest thermostat's Energy History records how often and for how long your system has run over the last 10 days. Energy History shows you how to make smart choices about your schedule and temperature preferences. You can view your Energy History with the app or on your thermostat. However, the Nest Temperature Sensor has no feature to check for the energy history records on the App. We hear your concerns, and have taken note of it.
