    Does the OPC UA client extension support bidirectional communication or just reading values from the server?

    With the OPC UA extension I was able to connect to the OPC UA server and read values. The config.json looks like:

     

    {

      "ws_connection": {

      "host" : "localhost",

      "port" : 80,

      "app_key" : "***",

      "thing_name" : "opcua_test",

      "encryption" : "none",

      "ignore_ssl_errors" :  true,

      "connect_retry_interval" : 10000,

      "connect_timeout" : 10000,

      "auto_scan_mode" : true,

      "scan_rate" : 5000,

      },

     

        "opcua_endpoint_connection": {

      "host" : "192.168.194.33",

      "port" : 53530,

      "server_name" : "OPCUA/SimulationServer",

      "security_mode" : "none",

      "request_timeout" : 60000,

      "identity_provider" : "anonymous"

        }

       

        "opcua_subscription": {

        "dataItems" : [ 

      {

        "name" : "MySwitch",

        "baseType" : "BOOLEAN",

        "identifier" : "MySwitch",

        "namespaceIndex" : 2,

        "isReadOnly" : false

        }

     

      ]

        }

    }

     

    Now i am trying to change the value of MySwitch from the Properties tab of the thing, but this doesn't work:
