The Home app makes smart home control even easier with new automation suggestions and expanded controls in Control Centre for quicker access to accessories and scenes. Adaptive Lighting for compatible HomeKit-enabled lights automatically adjusts the colour temperature throughout the day. The Home app and HomeKit are built to be private and secure, so all information about a user’s home accessories is end-to-end encrypted.
This means that as soon as iOS 14 is available you will be able to adjust the colour temperature of your lights according to the time of day, just like you are used to on your iPhone, where it is called "Night Shift". Night shift automatically shifts the colours of your display to the warmer end of the colour spectrum after dark. This may help you get a better night's sleep.
Also there a few new icons on the HomeApp, that will show the most important devices and events in your Home.
