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.
