- Status: Shows the connection status of the broker..
- Topic Status: Displays the status of the assigned topics (message channels).

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.
