  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.
--The Mosquitto client publishes messages (payloads) on the topic **v1/devices/me/telemetry**. Of course, you can use any topic for testing.
++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.
--(% id="cke_bm_37386S" style="display:none" %) (%%)The MQTT payload format is as follows, which is common for all **~-~-NB** and **~-~-CB** series devices. The **IMEI** field is mandatory and is used to provision a new device with the name assigned to it in ThingsBoard.
++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.
--{{code language="none"}}
--{"IMEI": "S31B-NB", "temperature": 27, ......}
--{{/code}}
--Once ThingsBoard receives this message, it automatically creates (provisions) the device mentioned in the **IMEI**, for example, S31B-NB.
++**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.**
--== 5.2 Sending messages ==
++For example, if you send two MQTT messages with different device names in the topic:
++1. v1/devices/**S31B-NB**/telemetry
++1. v1/devices/**S31B-CB**/telemetry
--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 S31B-NB and 27, respectively. This payload is also (technically) known as telemetry.
++ThingsBoard will create two devices named **S31B-NB** and **S31B-CB** in the **//Devices//** section.
++
++The MQTT payload format is as follows, for example:
++
  {{code language="none"}}
--mosquitto_pub -d -q 1 -h 011731f7928xxxxx.s1.eu.hivemq.cloud -p 8883 -t "v1/devices/me/telemetry" -u "xxxxx" -P "xxxxx" -m '{"IMEI": "S31B-NB", "temperature": 27}'
++{"temperature":10.4, "humidity":85}
  {{/code}}
--If the integration was performed without errors, the status of the integration changes to 'Active' after the first telemetry transmission.
++== 5.2 Sending messages ==
--[[image:integration-active.png]]
++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.
--Also, a new device named **S31B-NB** will appear under **//Entities -> Devices -> All//**. This means the first MQTT message triggers ThingsBoard to provision a device named **S31B-NB**.

--
--
--Go back to the **Integrations** page.

--
--Click on the **Edit** button (//**pen icon**//).
--
--Click on the **Disabled** button in the upper-right corner.
--
--Turn on the **All messages (15 min)** option. This will enable displaying all messages in the **Events** tab. This setting will expire in 15 minutes, and you will need to repeat the same steps if you want to view the messages in the Events tab later.
--

--Then click on the **Apply changes** (//**tick icon**//) button.
--
--

--
--
--Now go to the **Events** tab.
--
--Select the Event type as **Debug** from the dropdown list.
--
--Now you can see all the Uplink messages you are simulating through the MQTT broker. The status should be OK if there is no errors in your integration.
--

--= 7. Creating a Dashboard =
--
--ThingsBoard **Dashboards** provide a powerful way to visualize and monitor real-time and historical data from connected devices. They allow users to create interactive, customizable panels displaying telemetry data, device status, and other key metrics. With a variety of widgets, including charts, maps, and tables, dashboards help users gain insights, track trends, and manage IoT deployments efficiently.
--
--
--This section guides you on how to create a dashboard to display temperature and humidity data from the device on a time-series chart. You may also use other widgets in ThingsBoard to display data according to your requirements.
