Actually, according to the daily schedule, the LED should be off, but it still lights up, what is happening?

If you activate the moon, it will shine according to reality, this can also be during the day. This can of course be an undesirable effect. It is best to use a separate LED for the moon simulation. On http://www.mondverlauf.de/ you can check when the moon rises and sets, in one of the next versions you will be able to determine the GPS coordination for the calculation yourself.

Another helpful option that we will add soon is the setting of the period of the day where a moonrise can only happen.
