About the functionality:
Day Mode (5am to 5pm) - shows the current temperature and recommends the best sleep wear combination for naps based on the current room temperature.
Night Mode (5pm to 5am) - shows the lowest predicted overnight room temperature in the large text at the bottom of the thermometer icon, as well as the current temperature in small text on the icon scale bar (right side of the icon). Keep in mind that Night Mode is designed to work without the use of a heater - if you plan to turn your heater on overnight please factor that in when dressing baby for sleep.
The night light function will use the built in colour changing light to indicate to you at a glance the current temperature in the room, and so tell you how to dress your child without needing to look at the screen. It displays the below colours based on temperature:
Purple (less than 15° C)
Blue (between 15° C and 17° C)
Aqua (between 17° C and 19° C)
Green (between 19° C and 21° C)
Yellow (between 21° C and 23° C)
Orange (between 23° C and 25° C)
Red (greater than 25° C).
