+## MQTT
+
+The system includes an MQTT broker (Mosquitto) with WebSocket support:
+
+- **MQTT**: `localhost:1883`
+- **WebSocket**: `localhost:9001` or `/mqtt` via nginx
+
+To create a new MQTT user with a custom password:
+```bash
+docker run --rm -v $(pwd)/mosquitto/config:/temp eclipse-mosquitto mosquitto_passwd -b /temp/pwfile username password
+```
+
+Then restart the containers:
+```bash
+docker compose restart mosquitto
+```
+
 ## Development
 
 When you run `docker-compose up`, the backend automatically reloads when code changes (`--reload` flag). Just refresh your browser to see updates.
