What's New

5.15.23 (build 2631A)

12 August 2026

• LED RGBW DIN v4.0.3 and LED RGBW FM v3.0.1:
  • Changed the parameter order of the Switch method in the LED_CHANNEL and LED_CCT objects - the Mode parameter is now optional and passed last, after the Time and Ramp parameters, which restores backward compatibility with calls from previous versions.
  • Extended SwitchOn method in LED_CHANNEL and LED_CCT objects:
    • Added optional Mode parameter with two operating modes:
      • Default - turns the output on with MaxValue (previous behavior),
      • LastValue - turns the output on with the last non-zero value instead of MaxValue.

• Retention of the last value at which the output was on:
  • The value is stored every time the output is switched on or its value is changed,
  • The value is kept in the CLU non-volatile storage and restored after a CLU restart,
  • Calling the Switch or SwitchOn method with the Mode parameter set to LastValue turns the output on with the stored value,
  • In the LED_CCT object the brightness is stored together with the color temperature.

• Changed the behavior of the Ramp parameter set to 0 in the Switch, SwitchOn and SwitchOff methods of the LED_CHANNEL and LED_CCT objects - the value 0 now applies the ramp time from the RampTime feature instead of changing the output value immediately. The SetValue, SetColorTemp and Hold methods keep their previous behavior.

• Dimmer DIN and Dimmer FM v3.0.2:
  • Extended Switch and SwitchOn methods in the DIMM object:
    • Added optional Mode parameter with two operating modes:
      • Default - turns the output on with MaxValue (previous behavior),
      • LastValue - turns the output on with the last non-zero value.

• Retention of the last value at which the output was on:
  • The value is stored every time the output is switched on or its value is changed,
  • The value is kept in the CLU non-volatile storage and restored after a CLU restart,
  • Calling the Switch or SwitchOn method with the Mode parameter set to LastValue turns the output on with the stored value.

• Changed the behavior of the Ramp parameter set to 0 in the Switch, SwitchOn and SwitchOff methods - the value 0 now applies the ramp time from the RampTime feature instead of changing the output value immediately. The SetValue and Hold methods keep their previous behavior.

• Fixed button Hold behavior for the DALI_GEAR object - during a single hold the brightness now changes in one direction only, without alternating between brightening and dimming. In addition, in all objects the times of the Hold methods and of switching for a specified time are no longer extended when the CLU is heavily loaded with scripts.

5.15.18 (build 2623)

18 June 2026

• LED RGBW DIN version 4.0.2 - fix update devices with hwVersion = 2 (24-2-2).

8 June 2026

• LED RGBW DIN version 4.0.0 and LED RGBW FM version 3.0.0:
  • Added a new LED_CCT object for controlling luminaries with adjustable color temperature:
    • ColorTemp and ColorTemp% features - color temperature readings in Kelvin and as a percentage,
    • WarmValue and ColdValue features - calculated values ​​of the warm and cool white channels,
    • SetValue, SwitchOn, SwitchOff, Switch, and HoldValue / HoldValueUp / HoldValueDown methods - brightness and output switching control,
    • SetColorTemp and SetColorTempPercent methods - setting the color temperature in Kelvin or as a percentage,
    • HoldColorTemp and HoldColorTempWarm methods, HoldColorTempCool - smooth color temperature change and shifting it towards warm or cool white,
    • OnColorTempChange event - generated when the color temperature changes.

• Extended functionality of the Switch method in the LED_CHANNEL object:
  • Added Mode parameter with two operating modes:
    • Default - toggles the output state (previous behavior),
    • LastValue - restores the last non-zero brightness value instead of MaxValue when turned on.
