Thanks again @uchagani for taking a look at this. However, I think it needs to be specified like I have below, so we actually get the optional library ‘websocket-client’ installed as well. That’s key to the fix. Otherwise we’ll get the same result as before (no websocket-client library installed.)

samsungctl[websocket]==0.7.1

Not an expert on this but I think this the correct way to do it?

@Murph24 you're right. I tried it just now and with your updated string it downloads websocket. Updated PR to reflect it.
