Connectivity to Mqtt Tiles Dashboard

rahulbachloo

I have connected my bluetooth gateway to flespi broker on cloud.And now I am not able to make connection and parse the mqtt data on mqtt tiles dashboard.I have attached

the screenshot of both.

Your hub publishes a large json array of objects to topic /gw/pub/304a265a560c
In the widget, when configuring, you must use the final topic (/gw/pub/304a265a560c) in order to get full json. And after that, you can specify the json path to the data to display. However, if your hub is sending a mixed array, it cannot be used in widgets. Since you have to configure the final json path with array index.

Hi Dexif,
I requie some help from you to give me some examples in specifying the json path to the data to display in my case scenario.And According to you now
payload type earlier was set to string so now i have to change to json.

Suppose I want to parse TimeStamp,RSSI(dbm) or DataFormat as Keys from Array of Objects and I would want some examples specifying the payload path of all the above mentioned array of objects.In my case Topic =/gw/pub/304a265a560c by default.

dexif

Can you describe in detail what you want to do with this data? Can you configure the hub to send data somehow differently, or is this the only option? Can you tell me which hub you are using? How many devices are connected to the hub?

Hi Dexif,
I basically want to know now how to specify payload paths for Array of Objects so that I am able to create individual widgets for each values such as TimeStamp as text,RSSI as Gauge etc.The data can now be seen

coming on mqtt tiles platform.

Hi Dexif,
My Gateway is sending data of bluetooth beacons over mqtt protocol.the data format is raw and i cannot change it to structured so this is by default.I am sending data of a single beacon over gateway.

You can configure mqtt channel to split json array to different messages.

{
  "messages_ttl": 86400,
  "enabled": false,
  "name": "Hub data splitter",
  "configuration": {
    "clean_session": true,
    "client_id": "messages-splitter",
    "message": {
      "ident": {
        "source": "json_payload",
        "template": "%BLEMac(hex)%"
      },
      "payload_type": "json"
    },
    "skip_invalid": true,
    "subscribe": [
      {
        "qos": 0,
        "topic": "/gw/pub/304a265a560c"
      }
    ],
    "uri": "mqtt.flespi.io:1883",
    "username": "YOUR-TOKEN-HERE"
  },
  "commands_ttl": 86400,
   "protocol_id": 39
}

Just copy this json and paste to creation form (Click button to insert json)

Also you can create flespi devices to collect messages data by device.

{
  "messages_ttl": 31536000,
  "device_type_id": 172,
  "name": "gwD0FE41BEB558",
  "configuration": {
    "ident": "D0FE41BEB558"
  },
  "messages_rotate": 0
}

After that you can use device telemetry subscription to see your data splitted by device.
For example you can create multiplier widget with topic flespi/state/gw/devices/+/telemetry/TimeStamp
