MQTT ​

Here you can find the MQTT page within the nomos system Controller, showing the status of the built-in MQTT broker and letting you configure authentication for your own MQTT clients.

  1. Status:

    • Broker URL: Displays the address to point your own MQTT client at, i.e. the controller's address in the network (e.g., mqtt://192.168.0.199:1883).
    • Status: Shows the connection status of the broker..
    • Topic Status: Displays the status of the assigned topics (message channels).
    • Topic Subscriber: Number and details of clients receiving messages from a specific topic.
    • Topic Publisher: Number and details of clients sending messages to a specific topic.
  2. Help:

    • Clicking on the help button provides assistance with configuration or issues regarding the MQTT connection.
  3. Settings:

    • Authentication: Here you can configure the login your own MQTT client uses to connect to the broker. Leaving it empty allows connections without authentication.

Usage Notes:

  • MQTT is a lightweight messaging protocol specifically optimized for connections with minimal data traffic and low latency. It is widely used in the Smart Home sector to exchange messages between devices.
  • The MQTT broker acts as a central unit to distribute messages between clients (devices).
  • The controller always uses its own built-in MQTT broker; an external broker cannot be configured.
