# Features
* Eclipse Mosquitto: MQTT broker
* Node-RED: Flow-based development tool for visual programming and data flow automation
* InfluxDB: High-performance data storage
* Grafana: Real-time data visualization and monitoring dashboard

# Today's Goal
* install the stack
* configure one or two data sources
* transform data and store them in a database
* visualize data stored in the database

# Architecture
* 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.

Nodes are the important part of Node-RED, they:
* are triggered by either receiving a message object from a previous node or an external event like an MQTT event

- process messages or events and then passes them on to the next node
A node can:
* Inject: Starts a flow by injecting a message or a payload.
* Change: Here you can do basic transformation or modification on the message object.
* Debug: Can be used to help developing flows by sending messages to the side bar.
* Switch: Here you can add logic (like sending the message to different nodes).
* Function: Add custom JavaScript for uses cases where simple nodes do not do the trick.

InfluxDB is a database for any time series data. Time series data is everywhere, since time is a constituent of everything that is observable. As our world gets increasingly instrumented, sensors and systems are constantly emitting a relentless stream of time series data. For example:
* Electrical activity in the brain
* Rainfall measurements
* Monthly subscribers
* Heartbeats per minute
* Electricity consumed by a chain saw
