Live feed
MQTT broker monitor
not connected
MQTT is a publish/subscribe protocol: devices publish messages to a
topic (a path like home/esp8266/status), and a central
broker forwards each message to everyone subscribed to a
matching topic filter. Connect below and watch every message on the broker flow through live.

Live messages
0 messagesTopics & wildcards
Topics are slash-separated paths. Subscribe with wildcards:
+ matches one level (home/+/status), # matches the
rest (home/#, or just # for everything).
Retained messages
A retained message is stored by the broker as the
"last known value" for its topic, and delivered immediately to new subscribers — great
for a board's status. Our heartbeats are retained.
QoS levels
0 fire-and-forget, 1 at-least-once, 2 exactly-once. The playground uses QoS 0 — lightest, and fine for frequent telemetry where the next reading supersedes a lost one.
Try it
Click Use built-in broker — this server has one built in, so no
internet or external broker is needed. A demo fleet is already publishing on
home/demo/#. Publish PING to home/demo/cmd and
watch it echo back. That round-trip is pub/sub.
Projects
