With the central time control it is possible to set the time intervals of multiple widgets within a dashboard tab with only one adjustment
In order to display the central time control in the dashboard, a "channel" must be assigned to the widgets that are to be controlled via this. Here is an example. Afterwards, all widgets can be controlled with the same channel name via the central time control.
It is also possible to assign multiple channels per widget.
With the checkboxes "Enabled" and "Time control" you can select whether the widgets with channels can be controlled exclusively via the "central time control" or additionally via the time control in the widget.
