shed-pi

Introduction

A package to run a Raspberry Pi in an outbuilding such as a garden shed, for the internet of sheds.

Automated use cases:

• Weather station
• Garden lighting
• Security

TODO:

1. Fix: Bug: The script startup gets an incorrect time (Hasn't yet got the internet time)
2. Instructions on pinout

Wish list:

• Poetry (Not started)
• ASGI backend server (Daphne)
• Native webcomponent FE with Bootstrap
• pip install raspberry pi
• modular components that are easy to install from a software and hardware perspective
• Provide systemd script to 3rd parties
• venv is crucial before installing any third party packages!
• Pre commit config with ci integration

Installation

Enable interfaces

For any temperature sensors the 1 wire interface is required

sudo raspi-config

1. Select the option: "Interface Options"

2. Select the Option I7: "1-Wire"

3. Agree to installing the 1-Wire script

4. Reboot

sudo reboot

Sanity check that the 1 Wire data is available:

ls /sys/bus/w1/devices/

Check the value read, be sure to change "28-000003ebbf13" to the values listed above:

cat  /sys/bus/w1/devices/28-000003ebbf13/w1_slave

Script auto start with systemd

Create a file in systemd

nano /lib/systemd/system/shed-pi.service
