﻿Each CTM matrix contains the settings for the brightness (0...100%) for each full hour of the day (0:00 midnight, 1:00 a.m., 2:00 a.m....11:00 p.m.).
Depending on the time of day, the individual brightness values are called up one after the other as the daytime colour sequence runs down.
The values between two full hours are determined continuously every minute by linear interpolation to implement a smooth brightness progression.

In a CTM matrix, separate brightness values are always configured for each time. Whether a group or single device reacts only to the pre-programmed colour or additionally to the defined brightness value is defined by the parameter "Type of daytime colour sequence" on the parameter pages of the groups and single devices.

The brightness values stored in a CTM matrix can always be configured within the range of 0...100%.
If CTM brightness values are outside the brightness range defined by minimum and maximum brightness of assigned groups or single devices, the gateway limits the brightness to the specified limits when a daytime colour sequence is in progress.

The "brightness" parameters are available for each full hour of an CTM matrix. The default setting of the parameters depends on the time.
