MMM-PIR-Sensor Guide with Edits and Updates

StacheEnthusiast

I recently got the MMM-PIR-Sensor up and going and it’s working flawlessly. I wanted to give a little information as I had to parse this from different sources and some of the info is a bit dated.

I am relatively new to pi in general so definitely point it out if something isn’t right.

Below is a step by step for MMM-PIR-Sensor by paviro.

Navigate to your modules folder at cd ~/MagicMirror/modules
Execute git clone https://github.com/paviro/MMM-PIR-Sensor.git
Navigate to cd ~/MagicMirror/modules/MMM-PIR-Sensor

This is one area I got held up
The guide states to perform an npm install where a dated version(2.25) of wiring-pi would be installed.
When issuing the command gpio -v, I would get an error message “Unable to determine hardware version. I see: Hardware : BCM2835 - expecting BCM2708 or BCM2709. Please report this to project@drogon.net”.

Instead use npm install wiring-pi inside your MMM-PIR-Sensor folder. This will install the updated version(2.44) which you can verify with gpio -v.

Then issue command sudo usermod -a -G gpio pi
Then sudo chmod u+s /opt/vc/bin/tvservice && sudo chmod u+s /bin/chvt

The guide says to reboot here but after that, it still wasn’t working for me. Then I stumbled on some excellent advice from the forums here from @JamesMM with @strawberry 3.141 contributing.

Their focus was on the node_helper.js within the module. These are their edits.

First, rename the current file. mv node_helper.js node_helper_backup.js

Now, create a new file called node_helper.js using sudo nano node_helper.js

Copy and paste this code

'use strict';

const NodeHelper = require('node_helper');
const Gpio = require('onoff').Gpio;
const exec = require('child_process').exec;

module.exports = NodeHelper.create({

{
    this.started = false;
},

{
    if (this.config.relayPIN != false)
    {

            if (data.indexOf("0x120002") !== -1)

        // Setup value which represent on and off
        const valueOn = this.config.invertSensorValue ? 0 : 1;
        const valueOff = this.config.invertSensorValue ? 1 : 0;

        //Log.info('PIR: ' + this.name);

        //Setup pins
        this.pir = new Gpio(this.config.sensorPIN, 'in', 'both');

        if (this.config.relayPIN)
        {
            this.relay = new Gpio(this.config.relayPIN, 'out');
            this.relay.writeSync(this.config.relayOnState);
            exec("/opt/vc/bin/tvservice --preferred && sudo chvt 6 && sudo chvt 7", null);
        }

        //Detected movement
        this.pir.watch(function(err, value) {
            if (value == 1)
            {
                clearTimeout(self.timer);
                if (self.onState != 1)
                {
                    self.sendSocketNotification("USER_PRESENCE", true);
                    if (self.config.powerSaving)
                    {
                        self.activateMonitor();
                        self.onState = 1;
                    }
                }
            }
            else if (value == 0)
            {
                if (self.onState != 0)
                {
                    self.timer = setTimeout(function(){
                        self.sendSocketNotification("USER_PRESENCE", false);
                        if (self.config.powerSaving)
                        {
                            self.deactivateMonitor();
                            self.onState = 0;
                        }
                    }, self.config.offDelay);
                }
            }
        });

        this.started = true;

    }
    else if (notification === 'SCREEN_WAKEUP')
    {
        this.activateMonitor();
    }
}

});

This creates a new config called offDelay and it is in configurable in milliseconds.
Reboot your pi.

Then add the modules configuration to MM’s config.js. I used this but obviously adjust it to your own needs.

	{
		module: 'MMM-PIR-Sensor',
		config: {
			sensorPIN: 22,
			powerSaving: true,
			offDelay: 30000,
		}
	}

The offDelay of 30000 is 30 seconds.

I like people who write guides! I don’t use a PIR sensor but I do appreciate the time and effort you put in on everyone’s behalf.

@Mykle1

Thanks!

DavA

I followed your guide but i still get version 2.25 when i use npm install wiring-pi.
Any ideas why?

@StacheEnthusiast @DavA Hey, I just decided to try and install MMM-PIR-Sensor but am running into the same issue.
I was wondering if you ever did get this working as the directions have stated…

msherwood

shit, this killed my MM build…it’s all blank…crap

ardentaardvark

@msherwood Hey FYI I just got my lastest build (from scratch yesterday) working with MMM-PIR-Sensor:

I also found that npm install wiring-pi installed the old (2.25) version for me. I found a newer library:

npm install wiring-pi-2019

which installs version 2.5 (this one works on my pi4!).

I also found that the location of the tvservice binary has changed, so I just used the following bash commands:

sudo chmod u+s `which tvservice`
sudo chmod u+s `which chvt`

It then worked for me (Note, I did not modify the node_helper.js script at all.)

dubalda

Hi all, unfortunately I’m not too familiar with coding but had this module failed to update today having followed the steps above which worked fine with the previous version.

Has anyone else experienced this?

Thanks

Fozi

@dubalda can you elaborate more detailed the failure, e.g, error message or similar?

Feedy88

I am curious to know if there is a benefit by using the MM-Module for the PIR vs. the executable script which can be autostarted with pm2 (as per this tutorial). Can anyone help?

dubalda

@Fozi thank you for coming back to me. Here are the error messages I’m getting…apologies if it’s quite long! I unfortunately wasn’t able to upload the log file.

I‘d delete the module and re-install it. Obviously you haven’t changed any code (no info on stashing in the log). Your configuration will not be affected when you delete the module, it‘ll persist in config. js.

stop all processes with entering pm2 stop all.
cd to the module folder and enter: sudo rm -R MMM-PIR-Sensor. This will recursively remove the MMM-PIR-Sensor folder and it’s contents.
Re-install the module as described on GitHub. The installation build process should run through without errors.
Reboot

@Fozi rm -rf foldername will recursively remove all folders and content from foldername

@sdetweil looks like the wrong compiler level being used for the recompile.

Thanks guys, sorry for the late response! It’s the summer holidays so I’ve been doing daddy day care. I’ll try removing the module and reinstalling it. I’ll keep you posted.
