    Hi. We have followed the guide here : https://thingsboard.io/docs/iot-gateway/config/mqtt/ for using an iot gateway connected to mqtt broker. The problem is that no new device is shown in thingsboard devices after posting a demomessage like the one in example. e.g. this command should create a new device as in example: mosquitto_pub -h YOUR_MQTT_BROKER_HOST -p YOUR_MQTT_BROKER_PORT -t "/sensor/disconnect" -m '{"serialNumber":"SN-001"}'. We have checked acl on mqtt broker all is fine. The iot gateway device is connected.
    Sorru this command shoudl create a new device: mosquitto_pub -h YOUR_MQTT_BROKER_HOST -p YOUR_MQTT_BROKER_PORT -t "/sensor/data" -m '{"serialNumber": "SN-001", "sensorType": "Thermometer", "sensorModel": "T1000", "temp": 42, "hum": 58}'

    It seems the iot gateway connector does not pick up the messages and convert them. I have cheched logs and to me it seems the gateway is listening on the correct topic (sensor/data) but still nothing gets processed
    ""2022-04-28 07:59:51" - |INFO| - [mqtt_connector.py] - mqtt_connector - _on_subscribe - 333 - "MQTT Broker Connector" subscription success to topic /sensor/data, subscription message id = 1"

    Hi, I'm trying to create a new role where the customer can create and edit dashboards, but they can only use default widget libraries, not the ones I created. Is this possible?

    Hello! I can't get telemetry on Thingsboard PE over MQTT or HTTP. I can get telemetry on demo.thingsboard on the same ways I can't on PE. I tried integrations with a public MQTT broker where I can see JSON coming to the Integration and the Uplink but it wont result in telemetry. Can someone help me?

    Hi, I have a Maker subscription on TB Cloud and I have hit the 300M telemetry storage days limit. Current my data upload has been disabled. I have tried to delete all the TimeSeries telemetry data by using REST API but the "API Usage" dashboard still shows 300M/300M telemetry storage days used. Is there any way to resolve this? Thanks.

    Hi there, I've been tinkering with Thingsboard for use in an embedded product.

    I am using LwM2M, can an LwM2M device profile fautomatically provision a new device as part of the registration process?
    I can get it to work when I manually create the device but I can't find instructions to make it work this way.

    Hey, I would like to use "cell user content function" in an admin asset table to return the relation linked to the asset. For this, I use "entityRelationService.findByFromAndTypei" but it returns me an observable. When I use console.log to show the value, it works well, but when I return it, its not working (because it's asynchronous I guess). Do you have any idea how I can return value in the table? Thanks :)

    Hi everyone. I have question regarding the server-side RPC calls and the MQTT gateway API. Is there a way for me to make a RPC call to a device, connected to MQTT gateway device, via UI or REST? REST calls to http://<host>:<port>/api/plugins/rpc/ only seem to work for "regular" devices

    Hi Everyone, can anyone provide me pointers on how to disable device provisioning when connecting thingsboard-gateway with thingsboard? I have some devices communicating with Rest, and they are connected to gateway; and gateway creates device in thingsboard if there does not exist (which is the feature I would not like). Is there any possibility for that? Thank you and good day :)
