More of a question / Help really

There is a lot I do not understand yet with node-red... so I might be missing something with this node?

I need to be able to setup a flow that pulls the items to get values for from a DB, and also monitor for changes ( additions, remove ) of items... pass the list of items to the [ opc da in ] node... but need to cleanly deactivate when updating the group items...

Is there any way of setting up something like this using the [ opc da in ] node ?

Or is there a different lib I should try for this?

Yours is the only one I can get working with OPC DA for some reason... so.... hope I can figure out my question above with it!
