simple-motion-detector

Must be built on a ARM device if running on an ARM device.

What is this?

I have several motion detectors set up in my house. These devices are just raspberry pi's with a hc-sr501 sensor mounted on top. This repository contains code for connecting to the sensors via gpio and notifying a mqtt channel when motion has been detected. As I said previously, I have several of these set up in my house and they have been running for a good few months now. A service script is installed to run the program on boot. It uses Docker.

(If you're wondering, I run HomeAssistant and this was the easiest way to get notifications into it.)

To Setup

1. Install Docker (using this)
2. Pull this repository onto a raspberry pi.
3. Create .env file to hold environment variables in VAR=VAR format
4. chmod +x ./build.sh
5. ./build.sh

The build script will install a service file via systemd that starts the motion container after installation and on every boot. If there is an update to the code, run git pull in the directory and rerun the build script.

Todo

1. If the MQTT connection fails, we should retry a couple of times before exiting the process
2. Disconnect MQTT on shutdown?
