What is Smart Switching and what it is used for?

Modified on Fri, 05 Apr 2024 at 09:20 AM

With Smart Switching feature it is possible to use ordinary wall switches as dimmers or control scenes with them. The Smart Switching mode for the luminaire’s power switch can be configured in Casambi app. 

It is possible to assign different Smart Switching modes to each Casambi enabled luminaire. For example you can use Smart Switching to switch on several lamps when you come home or switch the lighting to be suitable for dinner party or watching a movie.  

Go to ‘Luminaires’ tab and double tap the lamp control you want to assign a Smart Switching mode to. Select ‘Luminaire Settings’ and under Smart Switch tap the current mode to open the Smart Switching selection. As a default the mode is ‘Dim and Save’

There are 12 different Smart Switching modes:

  • Not in use 
  • Dim and save
  • Cycle through modes
  • Control scenes
  • Cycle scenes
  • Active / Standby
  • Emergency
  • Presence
  • Presence/Absence
  • Absence
  • Resume automation (group)
  • Resume automation

Not in use

Sometimes it is necessary that the power switch doesn’t do anything special when used. Not in use option will disable our Smart Switching feature.

Dim and save — controls one luminaire

With Dim and Save you can use the lamp’s power switch to set a new default light level. Quickly flick the power switch first off and right away on again and the dimming process will start. When the light has reached the desired light level just quickly flick the power switch off and on again. Now the light level has been saved as a new default. The next time you switch on the lamp it will automatically go to the new default light level.

Cycle through modes — controls one luminaire

If you have set modes to the lamp from Casambi app you can assign the power switch to control the different modes. Modes can be different preset dimming levels, colours or colour temperatures. Flicking the power switch quickly off and on will cycle between the different modes and off.

Control scenes — controls one or multiple luminaires

If you have created scenes with Casambi app you can control them from a single lamp power switch. Just select which scene you want to control with the power switch and then using the power switch will control all the lamps in that scene. So switching on one lamp will switch on also all the other lamps in that scene.

Cycle scenes — controls one or multiple luminaires

If you have created different scenes with Casambi app you can cycle through them with one power switch. Select the scenes you would like to cycle through and flick the power switch off and on to cycle through the selected scenes and off.

Active / Standby — controls one or multiple luminaires

With Active/Standby Smart Switching mode you can control two scenes that have same luminaires in them. Create two scenes, one active scene that should turn on when the controlling luminaire is turned on and one Standby scene that is turned on when the controlling luminaire is turned off. This mode can be used for example with motion sensors.

Emergency —This option is only available with Evolution networks. This feature overrides any other control of selected luminaires in a defined scene. Despite the name, Emergency Smart Switching is not intended for true emergency lighting applications. It is more like an “override” option.


A scene is assigned to the Emergency Smart Switch device. When the power to the device is switched ON, the assigned scene is activated and will only be disabled when power to the device is switched OFF again. i.e. Any luminaires used in the scene cannot be controlled until the Emergency Smart Switched device is powered OFF.


Luminaires used in an “Emergency” scene MUST be powered separately from the Emergency Smart Switched device. i.e. The same power switch cannot be used to switch power to the luminaires in the scene and the Emergency Smart Switched device.

Presence  — Replicates the Presence mode of a sensor (see
Presence/Absence  — Replicates a presence/absence mode of a sensor

Absence  — Replicates the absence sensor of a sensor

Resume automation (group)  —  Resumes automation for a single group of luminaires

Resume automation  — (Resumes automation for all luminaires in the whole network

The CBU products that are directly powered from the mains supply are compatible with the smart switching.
