351 -On the terminal, issue the following MQTT command which simulates the device S31B-NB.
385 +== 5.1 How does it work? ==
352 352  
387 +We use the Mosquitto MQTT client to simulate MQTT messages, acting as a virtual device. First, install the Mosquitto client on your computer from [[this link>>url:https://mosquitto.org/download/]]. The Mosquitto client publishes messages to the MQTT broker (HiveMQ) on a specified MQTT topic. ThingsBoard subscribes to these messages using the same topic.
388 +
389 +The Mosquitto client publishes messages on the topic v1/devices/[device_name]/telemetry. The [device_name]placeholder can be replaced with any device name, for example, 'S31B-NB'. Then, the MQTT topic would be v1/devices/S31B-NB/telemetry.
390 +
391 +On the ThingsBoard side, we configure the MQTT topic subscription as v1/devices/+/telemetry. The + wildcard represents any device name and allows ThingsBoard to automatically create (provision) a device with that name, such as S31B-NB, for example.
392 +
393 +
394 +**The new device is created the first time the MQTT topic is received. For subsequent MQTT topics with the same device name, no duplicate devices will be created.**
395 +
396 +
397 +For example, if you send two MQTT messages with different device names in the topic:
398 +
399 +1. v1/devices/**S31B-NB**/telemetry
400 +1. v1/devices/**S31B-CB**/telemetry
401 +
402 +ThingsBoard will create two devices named **S31B-NB** and **S31B-CB** in the **//Devices//** section.
403 +
404 +
405 +The MQTT payload format is as follows, for example:
406 +
353 353  {{code language="none"}}
354 -mosquitto_pub -d -q 1 -h mqtt.eu.thingsboard.cloud -p 1883 -t v1/devices/S31B-NB/telemetry -u "24vk3w9h7sqdld1me5eh" -m "{temperature:20}"
408 +{"temperature":10.4, "humidity":85}
355 355  {{/code}}
356 356  
411 +
412 +== 5.2 Sending messages ==
413 +
414 +
415 +On the terminal, issue the following MQTT command which simulates the device S31B-NB. The message payload contains the fields temperature and humidity, which hold the values 10.4 and 85, respectively. This payload is also (technically) known as telemetry.
416 +
417 +{{code language="none"}}
418 +mosquitto_pub -d -q 1 -h 011731f7928541588a6cdfbbedfc63f4.s1.eu.hivemq.cloud -p 8883 -t "tb/mqtt-integration-tutorial/sensors/SN-001/telemetry" -u "pradeeka" -P "Kalpani123@" -m '{"temperature":10.4, "humidity":85}'
419 +{{/code}}
420 +
357 357  If the integration was performed without errors, after the transmission of the first telemetry, a new device with the name “S31B-NB” will appear in the Devices → All. Also, you can verify the input and output data, respectively, before and after conversion in Data converters → UDP Uplink Converter NB/CB → Events.
