Hello,
I need your help...
I need to subscrive to an Event on a OPC-UA server from Kistler.
With UA Expert, and can see the event being subscrive an can check the values, etc.
Using either 1. node-red-contrib-iiot-opcua or 2. node-red-contrib-opcua I can't seem to get any values.
The most I got was a system event trigger when the kistler sensor is actuated.
The source node is i=2253 (on ns=0), the Event type is ns=2;i=1, and the ValueType of what I need is ns=2;i=16
You can see UA Expert screens with the values I need to listen on the follwinf onedrive folder:
https://sinmetro-my.sharepoint.com/:f:/g/personal/rui_silva_sinmetro_pt/EnuLN_T7f21Ipg7FOr1l8CABD1D5IW9TxR6pVL0m2Oaebw?e=Midut7
On UA Expert I select the CycleDoneEventType, and then the Process Values.
I Get the events has seen in the image, and the values of the event.
At the end of the event I see that the event Type is ns2;i=1
On Node-red, I've tried configuring the flow using the examples provided by both packages.
On node-red-contrib-opcua I don't get anything... on the node-red terminal console (systemout) i get an error about "cannot find conditionRefreshId"
On node-red-contrib-iiot-opcua using the demo flow for event listener, and changing only the server address, i get a system event when the sensor is triggered (correct timing), but any configuration attempt after that I get object conversion errors or can't get any information.
I get that the problem is probably the way I'm configuring the flow.... but I don't know better 
My node-red-contrib-opcua (very simple)

I tried getting all events before any filtering... no luck
My node-red-contrib-iiot-opcua flow. Again tried getting everything and then filter... no luck.
If I try putting anything on the first node, I always get an "BadMonitoredItemFilterUnsupported" error on the debug console.

If I just leave the Server UA NODE on the "listen 200ms" node, i get a system event as shown below:
I think I've tried changing almost all configuration values on the nodes, to the ones I think were correct... bu no luck.
Thank you for any help you can provide.
