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.
