Yes! You can, for example, specify in the app from 21.00-08.00. Unfortunately, the light of the clock only switches on or off. Brighter/darker does not work. The operation without a mobile phone is also not very comprehensive. White or orange or spectrum, i.e. constantly changing colours. Brighter and darker as well as louder/quieter can be set directly on the lamp. Other colours can only be controlled via the app.
