I also keep my house at 79 degrees F during the day and 77 at night, but my RH is between 58 and 62% when I disable the humidity control feature.

I actually have 4 hygrometers spread around the house. One is part of a weather station that tracks the outdoor and indoor conditions. Two of them I have had for 8 years that are strictly measuring indoor conditions. Recently, I added another indoor unit. I am very certain that my humidity measurements are accurate, as they have never deviated more than about 2 percent from the others. If you are measuring indoor humidity, I recommend using at least two hygrometers because they are not as accurate as a thermometer.
