Motion Detector

[Jhonte]

@phoenixrising That is only an override for the defaults? Or am I missing something here. Working the same way with or without the config part.

Hey All,

I’ve followed all the instructions in this topic, and I’ve finally got it to work (RPi 3 + PS EYE camera) everything works well for a while, and then HDMI out stays inactive, moreover, the PS EYE Left LED (the blue one) shuts off, normal operation, both LEDs are ON, so there is definitely an issue with Raspbian itself, is there anyone which resolved this since the previous post ?

My config : https://pastebin.com/j7cKDBy3

Hi @alexyak !
Thanks for the module, it looks awesome!
I was trying to use it, at some point I could make it run, I mean, I can set the timeout and the monitor “wakes up” when the pi camera detects any movement.
But when the timeout reachs the limit time, the monitor get off, but after a few seconds it appears a message that says “not signal, cable disconect”.
Is there any way to avoid that alert?

Kind regards

Never monitors turn off by themselve as soon as there is no signal or after a few minutes without signal. Mine was a old that did not turn on/off automatically.
I used wiringpi to activate a relais that turns the current of the monitor on and off.

@danielis
Sorry I can’t get your point as English is not my first language.
What I’m saying is that when the camera does not detect any movement, and the timeout setted is out, the monitor does not show the mirror, but after a few seconds appears something like this:

[danielis]

OK
But if there is a movement detected - is then the mirror shown?

Why do you expect to see the mirror after the timeout?

The mirror must be on if there is a movement. And if there is no movement and the timeout is over, then is the mirror off.
That is what you want and what this module is doing.

I think your problem is that as soon as the mirror is off, your monitor should turn off - right?

@danielis said in Motion Detector:

ur problem is that as soon as the mirror is off, your monito

Yes sir, that is my problem, the module seems to be working fine, but it is a bit annoying to see the alert when the mirror is off

[danielis]

Yes, that was what I tried to say in my first post yesterday.
I had the same problem.
Old monitors do not turn off by themselve if there is no signal. Newer monitor do turn off, and all is fine.

My solution was tu use a relais to turn on/off the current of the monitor. Therefore I used a pin of the GPIOs to control the relais.

For controlling this GPIO pin I used the wiringpi library

I had to add some lines in the node_helper.js - please look at the lines with: exec("gpio -g …

module.exports = NodeHelper.create(

        //this.started = false;
        exec("gpio -g write 4 1", null);
        console.log('motiondetector started ...');
        console.log('monitor relais on');
  },
  activateMonitor: function ()
  {
        exec("gpio -g write 4 1", null);
        console.log(moment().format() + ' monitor relais on');
        //this.started = false;
  },
  deactivateMonitor: function ()
  {
        exec("gpio -g write 4 0", null);

        //this.started = false;
  },

      //const self = this;
      if (notification === 'MOTION_DETECTED')
      {
          //const self = this;

          this.activateMonitor();

@danielis Hi! I’ve tried, but still can’t get it. So I was thinking, instead of putting of the monitor, is it possible to show a black image for example?
So when it detects movement, the MM appears, and when not, a black photo is shown.
Is it possible?

@pepemujica
There is a module called HideAll (or something similar) which simply hides all modules and leaves a black background. Maybe you want to try it
