I would like to display data of different OPC-UA clients with a dashboard. The data for each client is more or less the same. Therefore I would like to create a group of dashboard widgets, for example in a subflow. Within each group only the ui_grp of the dashboard-widgets differs. The data is then to be shown on the Dashboard-tab side by side for each UPC-UA-client.
For the property "Group" there is only a drop-down menue, from where one can choose from already created ui_grps. That's why it feels I am currently forced to change the ui_grp-property by hand for each widget. This is very undesired, because I would like to keep the widget group as a whole "template" changeable, so that the appearance for the data of all OPC-UA clients is changed simultaneously when changes are made.
I was reading through the Node-Red pages on
- how to create your own node
- how to write functions
- grouping nodes
I was also considering to write a script wich goes through the .json-file of the flow and changes only the references to the ui_grp.
Both ways seem to be to much effort for such a seemingly simple adjustment.
Did I miss something? Am I on the wrong track somehow?
Is there a way to programmatically edit the properties of nodes, that are originally not meant to be parameterizable?
Or to simultaneously change a common property of different types of nodes (again: that seem not to be parameterizable)?
Thanks in advance for helpfull advice
