Topics currently in use

Topics can be retained by the message broker. In this case, the most recent event for that topic is sent to a client immediately upon subscription of that topic.

Structure of Topics

level0/level1/level2/level3/….

Level Content
0 realraum (indicates sensor information) or
action (indicates a request for action)
1 clientID. Either ID of sender (if topic[0] == realraum) or ID of recipient (if topic[0] == action)
Future use: access restrictions for topics of +/clientid/# to senders with the correct clientid
2 uniquely identifies the type and format of the payload. E.g. means is directly maps to a certain json object structure
3 discouraged, but could be used to distinguish between several types of sensors of the same type at the same location, subcommands, etc
Reasons
  • eg.:to get all temperature sensors in realraum, subscribe to: “realraum/+/temperature”
    e.g. mosquitto does not support wildcards subscriptions of the type “realraum/#/temperature”, which means message content/format should always be at level 2
  • “realraum/” should be at the front, since other hackerspaces MQTT sensors can also be subscribed to. e.g. “devlol/”, or “metalab/”
  • having the message format indicated in the topic makes parsing easier
  • having the clientID in the topic makes access control easier, e.g. only that clientid can publish to this topic

2nd level topics and payload types

see e.g. basicevents to get a feel for a payload message structure.
