# Project Name

## Milestones

### Milestone 1

The Goal is to display and visualize data received/measured from a Raspberry Pi on a webinterface.

### Milestone 2

The Raspberry Pi should be integratable to a Home Assistant Server and be used as as sensor input and opitionally logic level output.

### Milestone 3

Data should be sent and received via MQTT to an ESP32. The Pi acts as a sensor gateway.
