How to post your data using MQTT method​

  • Use the following MQTT topic to post the JSON payload of your variables

    • JSON Topic: /v1/device/{DEVICE_ID}
      • example: /v1/device/raspberry_pi

  • You can directly post raw values as well, use the following MQTT topic to post your raw values (example: 24) to a device variable

    • Value Topic: /v1/device/{DEVICE_ID}/variable/{VARIABLE_ID}
      • example: /v1/device/raspberry_pi/variable/INCOMER_B_AMPS

  • The payload must be a JSON object with the following structure :

{
"VARIABLE_ID_1": VALUE,
"VARIABLE_ID_2": VALUE,
"VARIABLE_ID_3": VALUE
}
  • Replace VARIABLE_ID_1,VARIABLE_ID_2 with your actual "VARIABLE_IDs" and VALUE with the actual Value you want to record.
  • You can get VARIABLE_IDs from -> Devices -> Show -> Variables tab.
