About

This repo holds some code that will be useful if you wish to host a static website on a solar powered Raspberry Pi.

Web Server

The compose.yaml can be used to re-create the hosting environment. The web server is Static Web Server and is perfect for a low powered device like the Pi. You'll need to add your Cloudflare tunnel key to the .env file where indicated. I use Podman, but Docker should be fine too.

Battery Monitor

The battmon folder contains a Python script that calculates the battery percentage, battery voltage, load, uptime and CPU temperature and then outputs it as JSON to be read by your website.

You'll need to initialise a Python venv and then install the required packages:

cd battmon
python3 -m venv .
./bin/pip install -r requirements.txt

The battmon.service file can be added to /etc/systemd/system/ and enabled with sudo systemctl daemon-reload, followed by sudo systemctl enable --now battmon.service.

Deployment

The deploy.sh script is used to clone and deploy my website to two Raspberry Pi hosts (one solar, one backup).

This project is ongoing and a full write up and hardware requirements can be found on my website:

My site is the one being served from the solar Pi!
