Remote IoT Sensor Monitoring via MQTT to InfluxDB - n8n Workflow | Neura Market
Remote IoT Sensor Monitoring via MQTT to InfluxDB
Automates capturing temperature/humidity data from MQTT-enabled IoT sensors (e.g., DHT22 on ESP32) and stores it in InfluxDB for real-time monitoring and analysis.
This workflow enables seamless integration of remote IoT sensors with n8n by using an MQTT Trigger node to subscribe to a specific topic, such as 'wokwi-weather', on a public Mosquitto broker. Incoming payloads from devices like an ESP32 microcontroller running MicroPython with a DHT22 sensor are parsed in a Code node to extract temperature and humidity values into proper JSON format. The data is then ingested into an InfluxDB bucket via an HTTP Request node, allowing for efficient time-series s

How to import this workflow into n8n
1Purchase or download the workflow to get the n8n workflow JSON file.
2In your n8n instance, open Workflows and choose "Import from File" (or paste the JSON with Ctrl+V on the canvas).
3Open each node marked with a credential warning and connect your own accounts and API keys.
4Run the workflow once manually to verify the data flow, then toggle it to Active.
