Data from 2 xenons to one argon

I am trying to figure out how to get data from more than one xenon to an argon. Specifically what shows the argon, or me i guess what data i got from which xenon. For instance 2 xenons publishing to the same subscribe (temperature) what defines what is from which device. I know this has been asked but after wanting to smash these things with a hammer all day just to join a network i decided to go this route. Please dont just say the particle docs.

With Mesh.subscribe() you subscribe to a prefix so any event that starts with that prefix will be investigated by the subscriber but the event publisher can attach its own ID to that event name and hence tell the subscriber where the event originated

But sorry that I can’t refrain from stressing the point: That could be found in the docs

Another source to investigate is this very forum
