## 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.
|
|
|

```
|
|
|
|
- `shell.nix`
|
|
This file is only used for the nix packagemananger to set up a development environment for the Webserver only
|
|
- `.envrc`
|
|
This is also a bit of linux nixos magic to automatically set up the development environment using direnv
|
|
- `main.py`
|
|
The main file for the project
