Send a test message

If you want to test publishing messages, you can use the "Send Message" feature in the management console. To do this, select a Thing from your Things List and select "Send Message" from the overflow menu at the top right of your screen

You can then pick the Thing that you want the message to appear to have been sent from, the topic that you wish to publish the message to, the message body and MQTT QoS to be used.

After you hit send, you'll see the message appear in the activity tab of the Things that it was sent from together with the activity tab of any Thigs that are subscribed to the topic you published to.
