410 410  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.

412 -The Mosquitto client publishes messages (payloads) on the topic **/device/a**. Of course, you can use any topic for testing.
390 +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.

395 +**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.**

399 +
400 +1. v1/devices/**S31B-NB**/telemetry
401 +1. v1/devices/**LDS25-NB**/telemetry
