Sorry, last comment. you get ALL data because you subscribed to `Module 22/#` that means you will get `Module 22/x` and `Module 22/sausage` and `Module 22/scoobydoobydoo` etc.

What are you _REALLY_ trying to do?

PS:

a better topic structure would be `module/22/xxxxx` this way you can subscribe to all modules `module/#` or a single module `module/22/#` or a specif topic of all modules `module/+/temperature`
