Demo Lab for MQTT 5
- FREE
Shared, read-only lab with
sensors publishing unique JSON messages with various telemetry
to the public brokers
BROKER.HIVEMQ.COM,
BROKER.EMQX.IO
that support the
new MQTT 5
.
Access the lab
here
.
See it in action in this Youtube video . You'll see the MQTT 5 subscriber client receiving arbitrary custom telemetry with arbitrary custom MQTT 5 user properties.
Each group of 10 sensors goes to a different broker as indicated by the
name on the first sensor. Pick the broker you
want, then modify the simulation if you want.
To change the temperature, select a running (green) sensor, invoke
the Agent->Variables menu item, and change the temp
variable.
See the temperature measurements change in real-time in your subscriber
client.
Test your subscriber applications by connecting to either of the 2 brokers,
eg. on BROKER.HIVEMQ.COM you can use a
web-sockets client with a SSL-connection to broker.hivemq.com:8000
as detailed
here
.

For MQTT 5 you'll need a subscriber client that supports this new version, eg.
the Paho C client
or
the MQTTX client
.
NOTE: Since it is shared, other people may be changing values at the same time you are. Lab is reset to known state at any point, but usually at midnight EST. If you want your own lab with these limitations removed, you can rent it here. .
