Dear Friend, thank you for this json address space definition lesson. I have got this error when i type your DemoStation sample script carefully, can you address this issue. "ReferenceError: addressSpace is not defined" Default adress space script for oil tank level and gas tank level is working and return "construct new address space for OPC UA"

Please Note: The name of the Node-Red package has changed, but it still works the same way. You can find the new OPCUA Server Node-Red Package here: flows.nodered.org/node/node-red-contrib-opcua-server
