385 -== 5.1 How does it work? ==
386 -
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 -
407 407  {{code language="none"}}
408 -{"temperature":10.4, "humidity":85}
270 +mosquitto_pub -d -q 1 -h mqtt.eu.thingsboard.cloud -p 1883 -t v1/devices/S31B-NB/telemetry -u "24vk3w9h7sqdld1me5eh" -m "{temperature:20}"
409 409  {{/code}}
410 410  
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 -

420 -
421 421  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.
