Hi, I have followed the video and installed the trial MQTT Transmission Module but for some reason it is not connected to localhost as the video states it should be. What do i need to check why its not working.

Thanks.

Are you running the broker in the same computer? (That's what localhost means.)

Take a look at the logs, there will be relevant details there. I also think (based on vague recollection of past experience) that it may show 0 of 0 if the _server_ that you're showing isn't part of a _server set_ that is selected by an active _transmitter_, i.e. if it is idle and doesn't need to connect.
