    @Naveenkumarg24 What do you mean how to check? Can you not simulate the condition you have set for the email notification and check whether the email is being received? Did you try that already and it did not work? Please explain a bit more for better understanding.
    @nmahale10 Good Question, let me know if you get the answer.

    Hi, I'm trying to avoid triggering alarm when there are already an active alarm for the same device and alarm type. Any ideas?

    Hey everyone,
    I am not getting message value in my device application script when I send a post command to the device. I followed the exact sample from mqtt extension configuration's server side rpc example https://thingsboard.io/docs/iot-gateway/mqtt/#server-side-rpc-commands
    I am running a node script which sends a connect message to gateway. I am able to see devicesOnline = 1 in Latest Telemetry, but when I am send a post command like this one curl -v -X POST -d @rpc-request.json $SERVER_BASE_URL/api/plugins/rpc/twoway/$DEVICE_ID
    --header "Content-Type:application/json"
    --header "X-Authorization: Bearer $JWT_TOKEN" my device application's node script gives the output:
    request.topic: sensor/SN-001/request/echo/5
    response.topic: sensor/SN-001/response/echo/5

    '5' is the request id that increments after every post command, but the request.body always shows empty, i take it should display 'Hello' as per the request body's "method.params" but nothing appears.
    I also installed Thingsboard IoT gateway 2.2.1 release.
    Any help is appreciated.

    Has anyone had success in platform integration with MQTTS?

    Hello everybody,
    I have wrote a tool for load testing for Thingsboard’s MQTT for the company I work for. I’m a system administrator and coding is not my main focus so we have decided to make this tool open source


    The main difference between this one and the the by thingboard development team that their tool doesn’t offer away to bulk remove/ delete the testing devices if a big test fails at any point, and if you have thousands of devices created you have to delete them manually. but in this script I’m using an external MySQL db to store created devices IDs and token so it is easier to deal with devices as you want
    I hope I find any contributors here and all feedback are very appreciated

    @directcontrol I was looking for this too, but did not find a way to achieve it using only Thingsboard - in the end we used a mosquitto broker for MQTTS and the Thingsboard gateway connects to it on a non-secure port but is running on the same server (or a private network). Maybe this will be supported in newer Thingsboard versions?
