58 at night and 68 during the day at our house. Blinds and curtains closed when the sun goes down and opened when the sun comes up. Old school solar heat. Down comforters are pretty warm and there are other ways of producing heat at night.
AC is run about a week every summer whenever we get a sustained heating spell in the upper 90's. Reversing the winter blinds routine and running ceiling fans at night makes the low humidity living of Colorado pretty comfortable for someone who grew up without AC in +90% humidity back east. I almost never run AC in my car. It goes on when we are on long drives across country and we are listening to something on the radio.
I never heard of NEST or learning thermostats. They must be from the devil![]()
