Uses a HC-SR04 ultrasonic distance sensor hooked up to a Raspberry Pi Zero WiFi to monitor whether my garage door is open. I made this so I don't have to turn around after leaving my house to check if I remembered to close the garage.

Written in python using the Quart framework.

• X-Api-Key header to prevent randos from posting fake data to my server
• SSE (server sent events) for live updates

• Remove all assumptions from deployment
• Generate ./config/garage-env based on .env
• Maybe send text message when opened
• Table of past open events
• Script for downloading new versions of htmx

• Install deps ./run.sh install
• Run local server ./run.sh
• Run simulated sensor ./run.sh fake-sensor
• Run tests ./run.sh tests
• Go to https://localhost:8081/garage/status

• .env exists and has the Env vars PI_USER,PI_SSH_HOST,SERVER_USER,SERVER_SSH_HOST set
• Raspi GPIO libs and python3-httpx are installed on the pi
• SERVER_USER exists on SERVER_SSH_HOST
• loginctl enable-linger SERVER_USER
• ./config/garage-env exists and has the Env vars GARAGE_API_KEY

./run.sh deploy-sensor

• Copy sensor.py and it's systemd service and environment files to the raspberry pi
• Stop and reload systemd service
• check status

./run.sh deploy-server does the following:

• Build .whl file for the garage package
• Copy the .whl file and it's systemd service/env files to my VPS
• Stop garage-server.service systemd service
• Clean up any previous virtual environments
• Create fresh venv
• Install build deps (wheel, setuptools) and .whl package into venv
• Load new service files systemctl daemon-reload
• Start garage-server.service
• Check status of garage-server
