Build MQTT Sensor InfluxDB Logger Workflow

Build an MQTT telemetry pipeline from template #161: when a sensor message arrives, write the payload to InfluxDB for trending and dashboards.

What this template does

1. MQTT Sensor Event — subscribes to sensors/+/telemetry.
2. Write to InfluxDB — measurement sensor_reading with topic tag.

Step 1 — Load the template

1. Studio → Templates → search MQTT Sensor InfluxDB.
2. Load template #161.

Step 2 — MQTT

1. Set broker host/port and topic filter to match your devices.
2. Publish a test message: mosquitto_pub -t sensors/temp01/telemetry -m '{"value":22.5}'

Step 3 — InfluxDB

1. Configure URL, token, org, bucket, measurement, and field mapping from {{payload}}.
2. Add tags such as {{topic}} for multi-sensor dashboards.

Step 4 — Activate on-prem

MQTT subscribe requires on-prem Studio or an exported runtime on the gateway PC. Export with Export Runtime to Edge if the broker runs on a factory LAN.
