Hi all,

a dashboard created with Node-RED can be accessed by more than one devices (if the url is known).  
Is it possible to detect which device is e.g. operating a dashboard node switch / button (e.g by reading the IP address, device name ...) and to inhibit this action?

Thx!

yes, look at ui-control node.

The UI Control node gives msg.socketid and msg.socketip when a client connects to the dashboard.  
And a button click sends socketid. Unfortunately the socketids don't match.

Ok, you mean I can use `socketip` from the message emitted by node `ui control` when somebody is doing what?  
In the help is mentioned 'changes tab'. Is that similar to 'operating and switch / button?

Nevertheless, I will test it and come back with questions again.

Thank you all!

When someone connect to the ui you can use the IP to disable tabs/groups, hide tabs/groups. or disable ability to run flow, it all depends on how you wish to code/run flow.

Clicking a UI button does not result in an output from ui-control, regardless of the ui-control node settings.  
Apparently it can do when the user changes tab or group, so maybe it would work if your buttons are each in a different group (not tried this yet)

Is there an example flow somewhere for this @E1cid?

@jbudd  
But if the socketids do not match how can i know from which user the button is clicked if the button (or switch) does not send IP address?

OK, I have now seen the latest answer from @E1cid and I understand that with this I can handle it. But as always: The devil is in the detail!

I hope you will help me when when it comes to implement it...

That's not working for me: my browser IP matches the one specified in the switch node, change node sends message to ui-control but both groups are visible.

Edit - updating and restarting node-red seems to have sorted it.
