Bi Directional MQTT to OPCUA Bridge

Expose MQTT topics to an OPCUA server via folders. Supports read/write.

Usage:

node creates an OPC server that:

  1. Connects to an MQTT broker
  2. Subscribes to '#' or a predefined set of topics
  3. On 1st Message of an unseen topic it creates the folder paths and node (last part of path) with nodeId s=topic
  4. On all onMessage calls, it keeps track of the topic's payload
  5. On Set requests it publishes the raw value from the OPCUA client
  6. On Get requests it returns the formatted persistant payload

Note:

Recently upgraded to support MQTT auth and to remove spaces from OPCUA name in example

PLEASE REMEMBER TO CHECK FOR UPDATES REGULARLY!

Todo: Add authentication

For configuration options and formatting of payloads, see handlers example below.

Please feel free to fork and improve.
