just tested now and writting a byte seems to work. And yes it expects an int between 0 and 254. what else did you try to write? looks like you tried to write something like b"2"
A possible improvment is to support hex notation but I am not sure there is really a need for it. but patch is welcome

Here's a screenshot of the attributes:

Changing that value to anything (0-254, or otherwise), spits out the above error. I think there is something in the GUI or widget that is converting my 2 to a b'2' (python's byte format).

Note: I have tested this with another client on a windows machine and I am able to change these values. So I know it's not a OPCUA or server issue.

Hallo , i am using opcua GUI client.
is there any way to customize this type of attributed representation, i need to send/subscribe a query to get only specific node , not all the node on the server side . So to do that i need to customize the code anyhow to be able to tell the server that i need this node (e.g: NodeId = 82), then the query should returns the attributes of the NodeId = 82

thanks in Advance for your Help
