﻿At this point, you can define when the gateway updates the feedback values for the colour status. The object values updated last by the gateway are then actively signalled to the KNX, provided the "Transmit" flags are set on the communication objects.

*after each update of feedback value*: The gateway updates the feedback value in the objects as soon as new telegrams are received to specify a colour value or values are specified by an internal function of the gateway (e. g. scene function, colour wheel sequence, HCL matrices). The default colour value does not necessarily have to change. Consequently, corresponding colour status telegrams are also generated, for example, in the event of cyclical telegrams to the input objects.

*only if the feedback value changes*: The gateway updates the colour status only when the telegram values also change. If the telegram values do not change (e. g. in the case of cyclical telegrams to the input objects with the same telegram value), the status remains unchanged. Consequently, no telegram with the same content is output repeatedly either.
