22 -== 3.1 Creat new MQTT integration ==
22 +**The following procedure is optional. If you haven't created any device in Thingseye first, Thingseye will automatically create a device for you based on the integration settings (the device name defined in the uplink decoder) just after it receives the first uplink from your device.Type your information message here.**
23 23  
24 -In the left navigation, click **Integrations center**, and then click **Integrations**.
24 +First, you need to create devices in Thingseye to represent your physical devices. For example, you can name it **Device A**, and the second device could be **Device B** or any name you prefer. The device name should be unique within the **Devices** space.

215 +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.

105 -The purpose of the decoder function is to parse the incoming data and metadata to a format that ThingsBoard can consume.

277 +Thingseye **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.

154 -* Configure client private key
279 +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 Thingseye to display data according to your requirements.

345 += 8. Configure Physical NB-IoT Sensor =
346 +
347 +Now, let's experiment with sending data to Thingseye using a real NB-IoT device. For example, we will use the **TS01-NB**.
348 +
349 +First, configure the NB-IoT device with the necessary MQTT settings using AT commands. Below is a list of AT commands you can use.
350 +
351 +**AT Commands**
352 +
353 +* **AT+PRO=3,3    **~/~/ Use MQTT to connect to Thingseye. Payload Type set to 3.
354 +* **AT+SUBTOPIC=<MQTT subscribe topic> Eg: TS01-NB**
355 +* **AT+PUBTOPIC=<MQTT publish topic> Eg: TS01-NB**
356 +* **AT+CLIENT=null**
357 +* **AT+UNAME=<MQTT Username>**
358 +* **AT+PWD=<MQTT Password>**
359 +* **AT+SERVADDR=<Broker address, Port>**
360 +
361 +Test your uplink by pressing the ACT button for 1 second.
186 186  
363 +
364 +The following image shows the uplink payload of a real Dragino device. The publish topic is '**TS01-NB' that contains fields in the payload, IMEI, IMSI, Model, temperature, etc**. Note that we have created a device named **TS01-NB** in the **Devices** section in advance.
