MQTT

1 min

The MQTT tab displays the Data Topic for an edge device to which you can subscribe. See About MQTT for more info about MQTT.

Notes:

The Connected state in the MQTT tab indicates that the browser is connected to the Litmus Edge Manager MQTT server with your edge device's configuration settings (username, password, MQTT host), and that you have the correct edge device settings configured.
The connection status of the physical device can be found in the Devices list.

Refer to the following actions you can take on the Litmus Edge Manager User UI's Edge Devices Details MQTT tab.
