PIR-Sensor - put your mirror to sleep if not used

MechMatt

@MechMatt On second thought, im having trouble with the relay as well… could you post a wiring diagram for the pi, relay, and tv? I’m not the best at electronics

paviro

To be honest the relay thing does not work that we’ll yet, still have to figure out some stuff related to how the Pi reacts when a monitor gets turned on after the boot process and not before.

As to your TV on/off button thing. The module simply puts s 3.3 volts on the configured Pin if the relay should be on and sets it back to 0 volts if it should be off. You can also configure it the other way around. Since I do not now how your TV button is wired I have no idea wheather it would work with this module without modifying some parts.

I’ve been using a python script to achieve this functionality, its worked well for me so far. I make sure the script is run at start up.

That’s exactly what this module does :)

Dear all,
I tried to implement the PIR-module. After I launch the MagicMirror i get always an error. What do I wrong?

That is what I have done:

Navigate into your MagicMirror’s modules folder and execute git clone https://github.com/paviro/MMM-PIR-Sensor.git. A new folder will appear navigate into it.
Execute npm install to install the node dependencies.
Add your user (pi?) to the gpio group by executing sudo useradd -g pi gpio.
Reboot your Pi.

And I wrote this in config.js:

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

After I start my mirror with npm start i get this error (from npm-debug.log):

@trividar from the earlier comments make sure you set your sensorPIN to an integer. (no quotes)

config.js:

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

trividar

@Knox thank you for your help. I try it, but I get the same error… I’m a noob and I realy don’t know what i do wrong…;o( Here is a foto of my error…

0_1464993890155_78f7b8c2-23a3-4342-ad75-84aa3c27a2ed.jpg

Have someone an idea what i do wrong?

THX a lot…

MichMich

As you can see it says it misses the module “wiring-pi” in the error part.

Try running npm install wiring-pi

Let me know if that solves the issue.

Even rolling back to node js V5 still results in a white screen. I realize people are saying that it’s a config issue but I’ve tried every combination there is and no go. I read the instructions and followed every letter and still no go.

I was using the monitor_on.sh and monitor_off.sh files from a different one but I cannot seem to get the pir.py file to work…

The problem with being new to all of this is that there is so much mis-information out there that you can literally spend hours doing the wrong things…

I was going to use the @reboot method to run the pir.py but have no way of knowing if it’s even loading because either I have a bad sensor or it’s just not working… it does show up in the crontab but not working…

On another note honestly I try not getting frustrated because this is fun for me to try and figure out…

BUT suggestions on how to get the pir.py to run on boot up?

Huge Thanks for ALL the hard work from everyone!! PS I’ve attached a copy of the pir.py and all files for anyone to take a look at and/or use…

This is the last thing I need to do to make this all work correctly and I can hang it :)0_1465667815133_PIR.zip

Thanks again!!!

cowboysdude

@cowboysdude OHHHHHHHHHH and how the heck do you really make the screen blank stop? I’ve tried EVERY method I could find online but the screen still blanks… :(

desq

@cowboysdude

I´m getting the same “blank” - white screen as soon as i try to use this module.
@cowboysdude do you have a solution yet?

cowboysdude

@desq No I don’t. Sorry I went in another direction… I have a pir.py and monitor_on, monitor_off.py… it works! If you’d like the setup I’d be happy to share…

You just start the pir.py using crontab -e then enter @reboot [point to where your pir.py is]…

That’s it… simple and it works!

desq

@cowboysdude
I got it. I installed the latest node. (6.2.1) Pull MMM-PIR from the git Repository und did all the steps Paviro explains on the module page.
And suddenly no more the white screen and the “USER_PRESENCE” notification is send every 5-6 sec.

@paviro
could implement a parameter to set the duration for a monitor shutdown as no USER_PRESENCE is detected?

Jaghova

A stupid question, where “USER_PRESENCE” notification must appear? in ‘PM2 logs mm’ ??

If so, It doesn’t appear in my logs, which means I don’t have the module correctly installed right?

But if i check on ‘GPIO readall’ I can see how the IN is activated and also the OUT relay when it detects presence

cowboysdude

@desq I’m not using the mmm-PIR I’m using something else… BUT I do know from reading that it wasn’t working with node V6… you had to roll back to V5.

I still had trouble with v5 so I went with something else…

desq

@cowboysdude mh… I really would like to stick with paviros module.
“USER_PRESENCE” (PIR Sensor) seems to work, but my Relay does not change it´s state.
@paviro can you confirm, that your PIR module doesn´t work with node 6.22?

If so I must switch to that python-script-hell.

paviro

@desq sorry no idea :D haven’t touched it in a while since I am pretty busy at the moment (finished school, now moving to a new city at the other side of the country). Could be possible that my dependencies work with v6 now but I still need to update it and change some stuff once I have the time :)
What exactly do you mean by duration? A delay? My PIR-Sensor can do that in hardware thats why I haven’t implemented it.

@paviro got a complete White screen and no posibility to use vnc. Got there the Same White screen and no option to open terminal anybody a solution so i can disable the module?

KirAsh4

@Wilco89, use SSH to log into it, user 'pi', password 'raspberry' unless you changed it to something else. Edit the config file, reboot the rpi.
