Overview Time / date



This control element displays the time and the date. By default the time is shown large in the first line and the date smaller underneath. Alternatively only the time, only the date or both values next to each other in a single line can be displayed. In addition an image can be shown on the left.

The displayed time is taken either from the linked addresses, from the controller or from the device the visualisation is running on.


Display

Format timeFormat of the time, default %H:%M (result e.g. "10:45"). The available placeholders are listed below.
Format dateFormat of the date, default %Y.%m.%d (result e.g. "2026.01.01").
Height dateShare of the lower line of the total height in the two line arrangement. This defines the size ratio between time and date (default 35 %).

Time source

Time sourceDevice (default): The time of the device the visualisation is running on is displayed.
Addresses: The time is taken from the group addresses linked below.
Controller: The time of the controller is displayed.
As long as no value of the selected source is available - in edit mode, without a connection or before the first telegram - the time of the device is displayed.

Image

SelectionImage that is shown to the left of the time display. Without a selection the whole area is used for the text.
Scaling"Like control element" fills the area of the image completely, "Proportional" keeps the aspect ratio of the image.
ZoomSize of the image, related to the height of the control element (100 % = square area over the full height). The text moves to the right by the used width.

Addresses

Time (EIS3 / DPT 10.001)Group address with the KNX time (3 byte). The data type of the address must be "EIS 3: time (3 byte)".
Date (EIS4 / DPT 11.001)Group address with the KNX date (3 byte). The data type of the address must be "EIS 4: date (3 byte)".
Date and time (DPT 19.001)Group address with date and time in one telegram (8 byte). The data type of the address must be "EIS 16: counter value (8 byte)". If this address is linked, it takes precedence over the two separate addresses for time and date.

The addresses can be written for example by the function block "KNX time server" or by a KNX device on the bus. Between two telegrams the display continues to run with second accuracy.
