Hi gyus, I've started using node-opcua lib and I am kinda new to OPC UA. I'd like to know if it is possible to setup some subscription and get notification only when the variable changes? From the tutorial it seems the subscription works like polling. Variable is read in regular intervals. Is there any other technique available to achieve this behaviour? Thank you very much

OK, but the value seems to be updated on the client at the intervals I specify in the subscription
I mean, client is not notified about the change in "real-time"
or am I missing something?
