Stream to thingsboard.io

alias0201

Hi everybody,
I am a new user of flespi service and let's say that I am a newbie in the MQTT world.
I would like to stream data to thingsboard.io and build charts and curves.
What I have put in place and it works:

1) Arduino ESP32 sending MQTT messages to flespi. Messages are in a JSON format and appear in the MQTT board under "messages/lumiNSG" topic like this:
{
ident : 276
valeurADC : 828
}

2) I successfully created a channel, connected to the above MQTT, and when I look in the toolbox tab of this channel I see incoming messages with associated value. e.g. valeurADC=745

3) In Telematics Hub, I created a stream to thingsboard.io withe the appropriate thingsboard.io token. Before I followed the steps descibed here: https://flespi.com/kb/how-to-set-up-stream-from-flespi-to-thingsboard
The stream apears in green so I asume it is correctly configured.

The problem: Data is not sent to thingsboard.io
1) When I go to thingsboard.io "Latest telemetry" I see nothing incoming.

2) in flespi, When I look to toolbox tab of the stream I see:
404: stream has sent messages 08/06/2021 08:57:56
{
accepted :1
event_code :404
origin_id :21669
origin_type :12
read :1
rejected :0
skipped :0
timestamp :1623135476.151581
}

Now I don't know where to look and make it to work. Any help in any direction is welcomed :)

Thank You.
Nicolas

Hi,
no answer so I reply to me as I found a solution, this may help somebody in the future.
In my JSON file generated from my Arduino ESP32 I was wrong.
This is wrong:
{
ident : 276
valeurADC : 828
}
And I replaced by that:
{
ident : "MyLolinD32"
valeurADC : 828
}
ident is the name of the device that will be automatically created in thingsboard.io
Now I am able to see telemetry in thingsboard.io coming from my flespi stream, based on a MQTT chanel. I can produce beautiful graphs :)

alias0201 Sorry for the delay. Integration with Thingsboard has always been kind of tricky.

Great that you finally fixed it. Next time you may contact us via integrated chat at top right corner of your flespi.io account and once we will quickly assist you there you may share your experience on the forum😉

Good day! I see that you are talking about thingsboard and its integration into flespi. I have a question, I already created my device with its channel and its stream to thingsboard and I managed to communicate it, I need help to know how to communicate many devices since the token in thingsboard cannot be repeated and the tokens are individual. It communicates to a single thingsboard device, how do I communicate to others with the same stream and channel for multiple devices?

EzequielRoldan take a look here: https://flespi.com/kb/how-to-set-up-stream-from-flespi-to-thingsboard
You need checked "Is gateway" option in Thingsboard device.
