Raspberry PI Weather Station

• powered by a Raspberry PI
• using a barometric sensor for temperature, humidity and pressure
• visualized using a webserver made with NiceGUI
• data is stored in a SQLite database
• E-Mail notifications for threshold violations via SMTP

SDA	GPIO 2

Follow the following guide: https://randomnerdtutorials.com/raspberry-pi-bme280-python/

Getting Started

• Install i2c-tools

sudo apt update
sudo apt install i2c-tools

• Enable i2c interface

sudo raspi-config
# Interfacing Options -> I2C -> Yes

• Install uv
• Install git
• Clone the repository onto your Raspberry PI
• Install the dependencies using uv sync
• If you want to access the web interface from another device, you need to use port forwarding. You can use the following command to forward the port:

ssh -L 8080:localhost:8080 pi@pi

• Run the application using uv run main.py
• Open the web interface at http://localhost:4444

24/7 Operation

• To run the application 24/7, you can use systemd to create a service. Create a file called weather-station.service in /etc/systemd/system/ like shown in the weather-station.service file in this repository. Make sure to adjust the paths to your setup. Then you can enable and start the service using the following commands:

• Create a symbolic link to the service file

sudo ln -s /home/pi/Documents/weather-station/weather-station.service /etc/systemd/system/weather-station.service

• Enable the service

sudo systemctl enable weather-station.service

• Start the service

sudo systemctl start weather-station.service

• Check the status of the service

sudo systemctl status weather-station.service

• Check the logs of the service

sudo journalctl -u weather-station.service -f
