Thanks @shal. That certainly got me connected to my server it seems.
Can't see any data yet, but I'll see what I can do from there.
I tried setting up a channel in the main page, but couldn't get that to connect to my broker so no clue what I was doing there. This looks a bit easier.
I'm trying to just get the text back from one topic at the moment.
In mqttx I subscribe to bango1/disp/status and it returns Watchdog feedback: 223
Should I be able to see this text in a label with the same topic? I juts get N/A at the moment.
Very much beginners stuff I know. Thanks for the help so far.
