Presence Simulation

Presence simulation: Greater security through intelligent timer technology

An empty house can quickly give the impression that nobody is at home. Particularly during the holiday season or when you are away for a longer period, irregular lighting can help to avoid this impression. With Grässlin’s presence simulation, the lighting can be controlled automatically and in a realistic manner.

A home that looks lived-in, even when nobody is there

Whilst switching lights on and off according to a fixed timetable is practical, it can quickly become predictable during prolonged absences. If, for example, the same light is switched on at exactly the same time every evening, it may be possible to deduce that the switching is automated.

Presence simulation therefore relies on varying switching patterns. The lighting is not switched on and off every day according to a rigid pattern, but simulates different usage times. This creates a more natural impression and makes the building appear to be occupied even whilst you are away.

Automatic control without manual effort

Presence simulation handles the switching operations automatically. Once set up, the lighting does not need to be controlled manually every day. This is particularly handy during holidays, business trips or other extended periods of absence.

The function can be integrated into the existing lighting control system, providing a convenient and automated solution.

Your benefits at a glance
  • More realistic lighting: Varying switch-on and switch-off times prevent a rigid pattern.
  • Automated operation: The lighting is controlled automatically.
  • Greater convenience: No need to switch the lights on and off manually every day.
  • An added sense of security: The building appears to be occupied even when you are away.
  • Integrated into smart Grässlin products: This function is available as standard in the smart solutions.

This means that the presence simulation feature is available regardless of the smart solution chosen. Depending on the application, users can select the appropriate timer technology to suit their individual requirements, whilst also benefiting from intelligent functions that offer greater convenience and security.

Smart timer technology for modern buildings

Presence simulation demonstrates how traditional timer technology can be enhanced with smart functions. Rather than simply switching lighting on and off at fixed times, this intelligent control system enables more flexible and realistic automation.

In this way, timer technology becomes a practical component of modern building automation, helping to combine comfort and security.

Intelligently combining security and comfort

With Grässlin’s presence simulation, lighting can be controlled automatically and in a varied manner whilst you are away. Changing switching patterns create the impression of an occupied building without the need to operate the lighting manually every day.

Whether it’s talento smart, FMD smart, tactic smart or topica smart: Grässlin’s smart solutions offer a convenient way to intelligently automate lighting and enhance your sense of security whilst you are away.
