Step 6 — Deploy the MQTT-InfluxDB Ingester

This article refers to Platform v3.0.0. The current Platform version is v3.2.0.

This step assumes the previous five steps are already running on the node (MQTT Broker → InfluxDB).

Overview

The MQTT-InfluxDB Ingester is the bridge between MQTT and InfluxDB. It subscribes to the YOLOv8 telemetry stream on the broker and writes every message into an InfluxDB bucket, ready to be queried from Grafana in the next step.

Deploy the Ingester

1. Open the Node Details page and click Add card → Application.

Add card menu

Select Application

2. Select app and version. Pick MQTT-InfluxDB Ingester and its latest version. Click Next.

Select Ingester

3. App Secrets. Keep the defaults and click Next.

4. App Config. Paste the JSON below — deviceDisplayName must match displayNameTelemetry from the YOLOv8 App Config (yolov8_telemetry_01).

   {
     "ingestorMqttInfluxdb": {
       "inputs": [
         {
           "bucketInflux": "bbrbucket",
           "dataFields": [],
           "dataTags": [],
           "deviceDisplayName": "yolov8_telemetry_01",
           "deviceNameInflux": "yolov8_telemetry_01",
           "deviceTags": [],
           "measurementInflux": "yolov8_telemetry",
           "subDeviceTags": [],
           "tags": "",
           "type": "read",
           "userTags": []
         }
       ],
       "system": {
         "bucketAutoCreate": true,
         "bucketAutoCreateRetention": 3600,
         "debugLevel": "info",
         "forceType": false
       }
     }
   }

   Key fields:

   Section	Parameter	Value	Description
   inputs	bucketInflux	bbrbucket	InfluxDB bucket to write into.
   inputs	deviceDisplayName	yolov8_telemetry_01	MQTT stream to read — the telemetry stream YOLOv8 publishes to.
   inputs	deviceNameInflux	yolov8_telemetry_01	Device identifier inside the InfluxDB measurement.
   inputs	measurementInflux	yolov8_telemetry	InfluxDB measurement that will hold the points.

5. Click Send App.

Send the Ingester deployment

Verify the deployment

The Ingester workload card appears on the Node Details page. When it turns green (Started), the bridge is up.

Confirm data lands in InfluxDB

1. Open the InfluxDB web UI at http://<NODE_IP>:8086 and log in.

   Parameter	Default value	Set in
   Port	8086	Compose Config
   User	bbruser	App Secrets
   Password	bbrpassword	App Secrets

   warning

   If your laptop is on a different network than the node, enable the VPN and use the node's VPN IP instead.

2. Open Data Explorer from the side menu and build a query against the bbrbucket bucket and the yolov8_telemetry measurement.

Points appear as YOLOv8 keeps publishing new telemetry messages — the bridge is working.

Summary

The Ingester closes the loop between MQTT and InfluxDB: every YOLOv8 telemetry message now lands as a point in the bbrbucket bucket under the yolov8_telemetry measurement, ready for Grafana to chart in Step 7.
