12.21 Application “2-button value dimming sensor”
With the "2-button value dimming sensor" application, it is possible to send 1-byte value
telegrams via an operation of the rocker. Each operation of the left or right side of the
rocker will increase or reduce a 1-byte value (percent or value from 0 to 255). The 1-byte
value can be connected with 1-byte brightness value objects of dimming actuators. This
allows a dimming actuator to be dimmed brighter or darker with the rocker via value
telegrams.
