MMM-Pir or MMM-PIR-Sensor

@svenpisa said in MMM-Pir or MMM-PIR-Sensor:

But when I wanted to install wiring-pi I got stuck at the following step:

That is just a usage step. You can ignore that. If you ran the npm install wiring-pi then you should be all set.

Hi Sam, I have now taken the instructions from you
https://pimylifeup.com/raspberry-pi-motion-sensor/ and have gone through them step by step.

I am using pin 15 (Gripo22)

I then edited the motion_sensor.py and entered pir_sensor = 15.
I simply ignored the piezo =7 entry as I only want to connect the PIR. So I really only entered pir_sensor = 15.

I have now entered the following in Config.js

		{
			module: 'MMM-Pir',
			position: 'top_left',
			config: {
				debug: false,
				delay: 1 * 60 * 1000,
				turnOffDisplay: true,
				mode: 1,
				ecoMode: true,
				displayCounter: true,
				displayBar: true,
				displayStyle: "SemiCircle",
				displayLastPresence: true,
				lastPresenceTimeFormat: "LL H:mm",
				mode6_gpio: 22,
				mode6_clearGpioValue: true,
				pir_gpio: 22,
				pir_reverseValue: false,
				xrandrForceRotation: "normal",
				wrandrForceRotation: "normal"
			}
		},

But I don’t have the feeling that the PIR is really reacting to my movements. I can stand in front of it or tap it with my finger, but the screen doesn’t wake up.
But strangely enough, the screen does wake up from time to time, which I don’t think is due to the PIR.

where is my mistake or am I using the following entry incorrectly? What is the purpose of the two entries?

				mode6_gpio: 22,
				mode6_clearGpioValue: true,
				pir_gpio: 22,
				pir_reverseValue: false,

As you can see the countdown runs down and goes back to full time but I have no idea why. I don’t think it’s because of the PIR… I can fiddle with it as much as I like… The time doesn’t change

@svenpisa that is why I wanted you to run the python script outside of MagicMirror to confirm the PIR sensor is working correctly, detecting presence

if it doesn’t work without MagicMirror it won’t work WITH MagicMirror either.

@sdetweil

I don’t understand that. I have done it exactly according to the tutorial and via

sudo python motion_sensor.py

to test the Pir. I could not recognize a new line immediately after a movement, but a line is generated every 5 seconds.
Since the tutorial says that the sensor waits 5 seconds until it queries again, I would have thought that it would work since the 1 is specified.

But now an entry is created directly every 5 seconds

I am open to all modules and settings to get the PIR up and running. If only I knew how to do it…

sdetweil

@svenpisa I don’t know exactly the problem…

the 5 second thing is in the code, not the PIR

it sounds like the pin number you are using is wrong, or the code is expecting no heat to be 0 and heat to be 1 ( pull up)

there are three different pin numbering orders and they are all different. sequential on the pi, and two others I can never remember.

until you get the python script showing motion/no motion, it cannot work under MagicMirror

svenpisa

Just for fun, I have now entered a different GPIO pin in sensor.py and started sudo python motion_sensor.py. Nothing happens here. So I have already selected the correct pin. But as you say, it’s probably the script.
How can I uninstall the motion sensor again? Simply delete the folder or is there a clean way?
I guess I’ll have to look for another solution, won’t I?

sdetweil

@svenpisa yes, just delete the folder

I have the same problem. The Module is not working, I tried so many parameter changes. Besides that I tried to read the values of the PIR with a python script and is working. To power on/off the monitor via console is working too. I don’t know what to try else

@Andrei-Leahu can you show the info from npm start.
Right after
starting application
