Been using nest for over 5 yrs and the damn thermostat has been changing my settings more and more over the years and I have to constantly reset them. No one wants there house set to 80 at 4am, and 54 at 4pm. The more this thing is around the dumber it becomes. I'm trashing our device and going back to my basic cheap device, Maybe then my bill won't be so damn ridiculous thank for wasting so much of my money. Don't buy unless you can afford to waste energy.
