The idea is to have a monitor app with which you can connect to an MQTT broker, subscribe to a number of topics and publish a text payload to a topic or two for debugging purposes.

The result is a pretty versatile utility for your MQTT toolchest. It serves as a viewer with which you can observe payloads being published to topics you're interested in, and you can publish payloads to topics at the tap of a button. The app is designed to work on both iPad and iPhone.

Completely unintuitive

Trial and error attempting to set up. Not at all clear how to do anything. For example, establishing a new session, not clear as to how to connect, when connected or not, why would not connect. Setting up a sub counterintuitive. Extremely poor UI. Very disappointed, waste of my two buck, but moreover a waste of time!

Not intuitive

Could not get this to work. The interface is not intuitive. Don’t waste $2

Works well

Program works well. The only thing I would love is to be able to have the publish buttons allow me to enter arbitrary numbers. This helps if, for example, you want to change a temperature setting.
