MMM MotionDetector Save

This is a motion detector module for MagicMirror

Project README

MMM-MotionDetector

Installation

Just clone the module into your MagicMirror modules folder.

Assuming you are in your MagicMirror directory execute these commands:

cd modules
git clone https://github.com/rejas/MMM-MotionDetector.git

Requirements

Accessing your (web)cam requires to have the client run on localhost or a HTTPS host (due to new requirements in Chrome for getUserMedia). The default value in your MagicMirror config.js is already localhost so most users shouldn't be affected.

Just in case you still have problems (like here) check your config and see if you can solve it by outcommenting the ip-address under

let config = {
    	address : '0.0.0.0',
	...

Raspberry Pi OS

Due to some changes on chromium and raspiOS (see https://github.com/rejas/MMM-MotionDetector/issues/56) the legacy raspios is needed.

Any help getting this module run on the default raspiOS is greatly appreciated!

Some people had success with enabling the legacy camera mode in the default raspiOS, but this is not a 100% confirmed:

sudo raspi-config

Then go to

3 Interface Options -> I1 Legacy Camera

and enable legacy camera support.

Tested devices

So far I only used a PlayStation3 Eye Webcam for motion-detection at my MagicMirror. If you have successfully used this module with any other webcam, I'd be happy to hear about it.

If you want to use the wired PI-camera follow these steps provided by @rev138:

- Open /etc/modules-load.d/modules.conf
- Add bcm2835-v4l2 to the end of the file and save it.
- Reboot.
- Profit

Another tutorial on how to enable the PI-camera in the browser can be found in this blog post.

Mac support

Thanks to 3vidar you can also use this module on a Mac. For now the code only resides in the branch called "mac" in this git repo.

I hope to find the time to generalize it and have it in the mainline too.

Configuration

To use this module, add it to the modules array in the config/config.js file:

modules: [
  {
    module: "MMM-MotionDetector",
    position: "top_left", // Optional. This can be any of the regions. Displays debug informations.
    config: {
      // The config property is optional.
      // See 'Configuration options' for more information.
    },
  },
];

Configuration options

The following properties can be configured:

Option Description
captureIntervalTime Time in ms between capturing images for detection

Default value: 1000
scoreThreshold Threshold minimum for an image to be considered significant

Default value: 20
timeout Time in ms after which monitor is turned off when no motion is detected

Set to -1 to never turn off the monitor

Default value: 120000
deviceId (optional) specify which camera to use in case multiple exist in the system.

How to get the deviceId

You need to retrieve the deviceId from the browser / electron instance you are running this module on.

  • If you are running it in a browser, use this command in the web console navigator.mediaDevices.enumerateDevices() to get all devices.
  • In the standard MM Electron, add 'export ELECTRON_ENABLE_LOGGING=true' to the mm.sh. Then cat the pm2 error logs and look for the DeviceID.

Configuring MotionDetector with another module that requires MagicMirror address to be 0.0.0.0

You can do this by doing a simple workaround. You need to config the MagicMirror address to localhost (default) and set up a reverse proxy for the other module.

As MagicMirror uses an express server, you can install http-proxy-middleware plugin for express. Then you need to create 2 files:

routes.json

{
  "routes": [
    {
      "route": "/mirror", // any path you like
      "address": "http://localhost:8080" // adrress of MagicMirror
    }
  ]
}

proxyserver.js

// Dependencies
const express = require('express');
const proxy = require('http-proxy-middleware');

// Config
const { routes } = require('./routes.json');

const app = express();

for (route of routes) {
    app.use(route.route,
        proxy({
            target: route.address,
            pathRewrite: (path, req) => {
                return path.split('/').slice(2).join('/'); // Could use replace, but take care of the leading '/'
            }
        })
    );
}

// Start server and listen on port 8081
app.listen(8081, () => {});

Now just start the proxyserver e.g. with PM2 like you may run your MagicMirror.

You can now call http://ipaddress:8081/mirror/modulename and it will be forwarded to http://localhost:8080/modulename.

As you are bypassing browser security with this workaround you may want to add some credentials and/or ip-ranges which can access your proxyserver.
