MQTTLAB.IOTSIM.IO/sparkplug

Portal for public SaaS MQTT labs based on MIMIC MQTT Simulator .

You can try it yourself for free (no registration/credit card required), then upgrade to paid lab if you like it:

Demo Lab with Sparkplug sensors - FREE

Shared, read-only lab with 100 EON nodes with Sparkplug sensors publishing unique Sparkplug messages with temperature telemetry to the public brokers IOT.ECLIPSE.ORG and BROKER.HIVEMQ.COM as detailed in the Sparkplug / Tahu specification.

Access the lab here .

See it in action in this 1-minute Youtube video.

To change the temperature, select a running (green) sensor, invoke the Agent->Variables menu item, and change the sensor11/XDK/temp variable.
See the temperature measurements change in real-time in your subscriber client.

Test your subscriber applications by connecting to BROKER.HIVEMQ.COM.
For web-sockets client, use a SSL-connection to broker.hivemq.com:8000 as detailed here. To see payloads, subscribe to topic spBv1.0/#

You can see published messages with a MQTT subscriber client , but since the messages are binary, you'll need one that decodes the Sparkplug protocol, eg.

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.
