Read and store IOT sensor data with the MQTT Trigger and InfluxDB

This workflow is for users wanting a practical example of how to obtain data from remote IOT systems using the MQTT protocol in an n8n environment.

The template provides typical n8n node implementation and configuration settings necessary to read and store IOT data.

The workflow reads the temperature and humidity data from a remote IOT system in this case a DHT22 sensor connected to a ESP32 micro controller. The data is parsed into the correct JSON format and then ingested in an InfluxDB data bucket. From there the stored temperature and humidity values can be displayed in real time.

The workflow can be easily modified to read any MQTT driven device data.
