There is a python implementation of OPC-UA that you should be able to implement into Hass.

The advantage of having an OPC integration is it automatically opens up a huge range of integration options, from CCTV systems to Industrial equipment

Yes!
We need to make this component.
Just to reawaken this Thrad: I am very interested in an OPC UA integration as the relevance of OPC UA is constantly growing.
Unfortunately I am not very experienced with the development of new components, but I know OPC UA and especially the Python-Opcua library. It would be great if someone could help me develop an OPC UA component for HA.

how do you install FreeOpcUa onto Home Assistant OS ?
If I do that on my Hassio Home Assistant I get :
➜ ~ pip install opcua
