Everyone has their own comfort level with luminance, humidity and temperature. Like in the evening we don't need as much light and it is good to easily set it to an acceptable level while just lying in bed. Same with humidity and temperature. Both are invisible but playing important part in an apartment to feel at home. During summer everyone loves to come home to a refreshing temperature and just enjoy that our home isn't as warm as it is outside, but in the winter it is good to feel the warmth after hours spent outside. This feature working with the proper sensors allow us to keep on track all the numbers, and easily modify them in a single second to the desired degree.
