## Architecture overview
Data is collected by IoT devices, e.g. an ESP32 based power monitor. These devices *publish* their data via MQTT into a topic in a message broker. We use Eclipse Mosquitto as a MQTT message broker.
Node-RED is used to read and transform or combine data and to implement more sophicsticated use cases like notifications or worksflow. Node-RED *subscribes* to topics in Mosquitto and can be used to save transformed data into a database.
As our data is bases on time, we are using a *time series database* to store information. We used InfluxDB as this database.
Dashboards can already be created in Node-RED, but to be more flexible (and include more options) we are using Grafana. Grafana reads data from our *database* and *other sources* (like CSV files on the Internet) and displays them in a nice dashboard.
