## Network
## GUI Usage
A GUI has been developed for easy configuration and plotting of key parameters.
The Python GUI program is located at pytec/tec_qt.py.
The GUI is developed based on the Python library pyqtgraph. The GUI can be configured and launched automatically by running:
```
nix run .#thermostat_gui
```
## Command Line Usage
