I have dashboard running on a touch screen. The touch part went bad, is there a way to use a timer to change the active screen?
Do you mean to cycle through a number of dashboard tabs, for example show a different tab every minute?
If so, take a look at the ui-control node in the node-red-dashboard.
If it's not what you mean, please provide more information.
From the help text in side panel for ui-control node.
The default function is to change the currently displayed tab.
msg.payloadshould either be an object of the form{"tab":"my_tab_name"}, or just be the tab name or numeric index (from 0) of the tab or link to be displayed.

here is a crude example that generates a random page cycle, With a little tweaking I sure you could make it cycle, and select which tabs you want.
Also I think string “+1” will move to next tab and “-1” for previous and should loopok as well
