MQTT access to LoRa devices?


I have a set of sensors connected via LoRaWan, through the Thing Network. That seems to be working just fine.

How can I get access to the current status of those devices from a third device, say, a raspberry pi running a program that utilizes MQTT?

An equivalent question would be, if I’ve added a raspberry pi to my account, as per the tutorial, can I get at the, say, CPU usage via software on a third device?
