Scrolling Dashboard Pages

[arneym]

I have many dashboard pages in my project. Some pages are for a specific machine, and some are for a specific department. Is there a node or solution on how to scroll through the pages on my dashboard?

Example:
Total number of pages: 25
Number of pages to be scrolled: 5
Page numbers to be scrolled: /ui/#/0, /ui/#/3, /ui/#/7, /ui/#/9, /ui/#/13

Thanks,
Mike

Automatically you mean ? On a timed basis like an info kiosk type display ?

Yes, automatically scroll after a set time in seconds.

The ui_control node can be used to control which tab is being displayed. That's your starting point for a flow that sends appropriate messages to that node at regular intervals.

Hi Mike,

This flow should work. The function node generates a cyclic output for each of the tab numbers hard coded in the array tabs.

Thank you @knolleary and @Andrei! This worked perfectly.
I found another issue on my end. Like I said earlier, I have 25 tabs that show many other processes in our manufacturing plant. I have a Raspberry Pi and a TV at each process. I have the default home page of each process opening to their respective tab. Can I have each Raspberry Pi/ TV scroll the tabs that are specific for their respective process?

Example:

1.) Main Pi runs Dashboard

2.) Pi from Turning department scrolls through tabs [0,9,10,11,12,13] on Main Pi.

3.) Pi from Grinding department scrolls through tabs [1,7,8]

Thanks,
Mike

If they are separate Pi then they are presumably running their own flows... so just customise the function in each flow to each Pi... ?

There are of course more sophisticated ways to allow the same flow to run on each and pick up and external environment number in order to customise each - but no idea if that level of sophistication is required here yet.

You nailed it on the head @dceejay ! I am currently running a behemoth node red dashboard on one Windows PC and pointing the Raspberry Pis to the Windows PC Site. I noticed that he performance is slow on the Windows NodeRed instance, probably because I have 28 tabs.

I will export the flows that I need to each process' Pi. I will just need to create a few higher level views on the Windows PC Dashboard for mobile and Manager viewing.

Thanks,
Mike
