This can be used for projects, for example for sensor data. Host We run 2 MQTT brokers, one on saturn and on roonadan.lan (192.168.1.189). Both are bridged together, so all messages will be forwarded to each other. Sandbox Under the topic sandbox/# you can play around and send messages. Topics used The following topics are ACL restricted. Your MQTT client needs to have a valid login and the according permission to read/write on the topics. Ask metalgamer on how to get an account.
