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

IngmarSwart

@KirAsh4 I agree, it’s very strange. Like you, I am using a rPi-3 with the most recent version of Raspbian Jessie and run everything as user pi. So maybe it is the monitor (Philips 273V5l). Which one do you use?

Although the problem is fixed, I would like to know what is going on.

KirAsh4

Let me get home and get you the details on it. It a monitor we had sitting around at the office, some high end graphic Pro monitor that wasn’t being used anymore. I also have a test I want to perform on it, see if that makes a difference in what I’m seeing. Stay tuned.

@paviro I donwloaded to node 5.0.0 and I know get the following error

Failed at the magicmirror@2.0.0 start script 'electron js/electron.js'.

paviro

@joerod That’s all? Not a failure of my plugin. Any more logs?

For people who are not confortable with programming this, or need to buy a pir sensor anyway

You can also buy a pir with motionsensor like this

I’ve tested my PIR sensor with a Python script to make sure I’m using the proper GPIO and its functioning as it should. I do see 1 & 0 when I move near the sensor so I don’t think its the hardware.

I’d love to use this module, I was going to do it in python but since you have it in JS I figured why not use that.

@joerod please use Markdown on code snippets so it is easier to read! :) have you installed all the dependencies (also for the mirror itself?)
@MichMich any idea?

MichMich

Sorry, no clue. :(

joerod

@paviro I had to downgrade to node 5.0.0, I confirmed its that version of node. After the downgrade I removed the PIR module and did a git clone and then npm install in the folder. Still the same thing, is there a specific version of node 5 I should be using or a specific version of npm?

I’m running it from
/home/pi/MagicMirror/modules/MMM-PIR-Sensor

MichMich

Could you try it with node serveronly ?

paviro

@joerod also do npm install on the mm folder or install the whole thing from scratch :)

@paviro as a feedback: i used the latest MMM branch and yours and it is working fine with my PIR sensor on a rpi2. I didn’t had to downgrade anything to node 5 (and i also don’t know what it is :D ) Thanks for your work. It is so great that the mirror is starting if a presence is detected!!

paviro

@DirkS glad to hear! :)

Hey Everyone!
I am trying to use this module to turn off/on a tv and im having a bit of trouble on the physical end of things… I got the module working perfectly (tested it with PIR and hdmi on/off). Now I am trying to use a relay with the PIR sensor to have the TV screen itself turn on and off. I was planning on wiring this to the TV power button (so it is essentially the same as pressing the on/off button).

I got the relay working… and I was about to take apart my tv when i thought…will even work for the on/off button? When it senses movement it will send the signal and then … turn off the tv I guess. As soon as the movement is undetected it stops sending the signal (or really pulse in this case)… just stopping wouldn’t turn the tv back on either. I guess it needs to send a pulse when it stops detecting movement, and then another one when it does again. Am I thinking about this wrong? Should I wire it to something else? Thanks in advance

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.

joerod

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.

paviro

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
		}
	},
