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}
	369	+mosquitto_pub -d -q 1 -h mqtt.eu.thingsboard.cloud -p 1883 -t v1/devices/S31B-NB/telemetry -u "24vk3w9h7sqdld1me5eh" -m "{temperature:20}"

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.

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.
