Efficient recipe for getting MQTT data into an InfluxDB database using Node-Red
Recipe: from MQTT to InfluxDB via Node-RED
2024-05-16 adds case study explaining how to extract values from topic strings, and how to specify the measurement name in the message payload provided to the "influxdb out" node.
2023-12-02 revise graphics to correspond with "influxdb out" node, and explain the pros and cons of InfluxDB 1.8 vs InfluxDB 2.
Introduction
Getting data produced by IoT sensors into a database is practically a mandatory step before effective visualisation (eg dashboards).
This recipe shows you how to get an MQTT payload into an InfluxDB database using three Node-RED nodes. It makes the following assumptions:
