Location Control

Require: IP-Symcon >= 4.0


The location control module offers the possibility to calculate twilight times. This simply requires the longitude and latitude of the location to be calculated.

Integration in IP-Symcon

configuration page

In the “Location” instance (“Logical Tree View” -> “Core Instances”), the longitude N and latitude E can be entered to exactly 2 decimal places. A method for determining latitude and longitude can be found under Tips & Tricks .

Thereby civil, nautical and astronomical twilight values for sunrise and sunset are calculated.
The two selection menus start of day and end of day form the boundary between which the boolean variable “Is it day” is set to true.

Core instance overview

The twilight values also determine the time of recalculation. This entails that when the time for sunrise is reached, the new value for the next sunrise is calculated.


An example would be a script to move down the shutters. This is started automatically when it is executed by an event that reacts to the variable change of “Sunset”.
