Bugsounet and MMM-Pir

[coernel]

I also just looked for the module as I wanted to contribute some troubleshooting guide and didn’t find it.

As I have installed the module, what do you think about re-publishing it so that it doesn’t get lost?
It is MIT-license so no problem about that!

[coernel]

I have re-published it already: https://github.com/Coernel82/MMM-Pir

@coernel please add it to the third party list

Hi,

Is this the correct place to ask questions about the module?

If so, is there any way to test that it is actually running?

I have installed the module for using a PIR module but nothing appears in the screen in the place I requested it.

Thanks

@lif have you verified that the PIR is working outside of MagicMirror??

Yes,

[sdetweil]

@lif and you are using the correct pin definition

    Pir: {
      mode: 0,
      gpio: 21
    },

Yes, the working script is:
from gpiozero import MotionSensor
from datetime import datetime
import os, time
import RPi.GPIO as GPIO

pir = MotionSensor(21)
while True:

    pir.wait_for_motion()
    now = datetime.now()
    current_time = now.strftime("%H:%M:%S")
    print("Movement detected at", current_time)
    pir.wait_for_no_motion()

@lif I meant MMM-PIR config setup

there are different numbering schemes for GPIO pins and different ways to access

the doc (readme) describes the different choices.

Yes, I think so, the pir is connected to pin 40 on the Raspberry pi 3b which I’m sure is GPIO 21

@lif and if you change to mode 1?? which matches your python lib test?

No difference.

I have added a header: “PIR”, line before the config and that is not showing either.

@lif are there any errors listed in the MM startup messages??

if using pm2 to auto start

pm2 logs --lines =xxx

xxx is number of most recent lines to display, default 15,
usually need 100 or more for full message list

Thanks for all your help
I think this line might be relevant

It’s correct, there isn’t a MMM-Pir.js file in the MMM-Pir directory.

[sdetweil]

@lif module rules

module name (exact case) = folder name in modules folder
MUST contain at minimum a file name that matches(exact case) of the modulename.js

AND inside that file it MUST contain a module.register(name…)
where name MUST match (exact case) the module name

If you had cloned this repository from @coernel - the MMM-pir.js is missing.
This must be an error.

Nevertheless: I’ve played around with the original version from bugsounet and figured out that editing his “origin” MM-Pir.js was really hard because he has deleted all linefeeds.
Seeking around I found an editable clone of the *.js files (including node_helper) in the src folder of the repository.
This is true for the new clone from coernel …
give it a try :-)

:-) never seen this before…

On a production web site with 1000000’s of file loads, minified can reduce response times…

otherwise it is a hiding technique, which can(has) hidden hacker attacks on client systems…(loading files, sending credentials…)
hard to examine code

Yes, I guess this was bugsounet’s intention - irritating beginners :-)

The code has 247 lines so you avoid 247 CR’s - not THAT much more efficient, I think - but on 100eds of 1000nds of files - may be …
