[Electron] display en screen after installing MMM-PIR-Sensor

[sdetweil]

@RIKKO14 i see this
0|mm | [2020-08-21 19:37:58.395] [LOG] [LPCM16] WARN: arecord: pcm_read
:2145: erreur en lecture: Appel système interrompu
and this
0|mm | [2020-08-21 19:43:41.435] [LOG] [Error: failed to read sensor]

so we may have to look at t he browser dev window,
ctrl-shift-i on the mirror keyboard
select the tab labebled console,
and scroll up to see any errors, usually in red text

[RIKKO14]

ctrl+shift+i on the mirror keyboard : nothing displayed
ctrl+shift+i on my pc keyboard : this is displayed :

[RIKKO14]

ctrl+shift+i on the mirror keyboard : nothing displayed : because my screen is powered off : source of the issue…

[sdetweil]

@RIKKO14 too small to read

[sdetweil]

@RIKKO14 i think the ‘failed to read the sensor’ error lead to the power off command being issued…

but don’t know

@RIKKO14 that is dev window open on forum page, not MM page

[RIKKO14]

that’s te problem…
you ask me to do ctrl+shift+i on the mirror keyboard :
but the screen is powered off so nothing displayed, i don’t know if it’s displayed something, I can’t see it…
or i don’t anderstand to acceed MM page with my pc, I have only this :

[sdetweil]

@RIKKO14 edit the config.js on the mirror

change address and ipWhitelist like this

address:"0.0.0.0",
ipWhitelist:[],

restart mm…

now on your pc you can do
http://pi_ip:8080

and then u can open the dev window on that page

i thought you said earlier you had removed the command to make your mirror screen turn off
so you know which code is issuing the command… tell where that was

[RIKKO14]

But I have only acces to my MM with SSH, so how to edit the config.js on the mirror with ssh ?

[sdetweil]

@RIKKO14 on the ssh terminal, (its a terminal window, same as works on pi)

cd MagicMirror/config
nano config.js

fix the text (move the cursor with the arrow keys and type and backspace
then ctrl-o to write the changes back out and ctrl -x to exit nano
then type pm2 restart 0

for your windows box, get winscp, then u can connect to pi as both terminal window (for commands)
and a file system view, like windows, double click on folder to go in, or file to edit… use your favorite pc editor (I use notepad++_)

[RIKKO14]

I do this :

and type pm2 restart 0, but my screen of MM is steel powered off…

[sdetweil]

@RIKKO14 now on your PC, open browser to
http://pi_ip:8080

same up address u used for ssh

now see magic mirror

[sdetweil]

@sdetweil and disable the PIR module in config.js, and manually turn screen back on

I’d this a Pi4. the off command works, the old on command doesn’t. I have seen others fight this but don’t remember any solution

[RIKKO14]

I reinstalled everything last night except the GA module and had the same problem.
This morning I start all over again with the MMM-PIR module and the [Electron] screen is displayed instead of my MM screen.
My pm2 log indicated that there is a Node.js version pb: I am in version 73 while the require version is version 64.
So I put an issue on the link of this module to request an update of the module with Node.js version 73, hoping that there is only that.
In the meantime I put aside this module and reinstall all the modules for the X time.
my pm2 log :

0|mm       | was compiled against a different Node.js version using
0|mm       | NODE_MODULE_VERSION 64. This version of Node.js requires
0|mm       | NODE_MODULE_VERSION 73. Please try re-compiling or re-installing
0|mm       | the module (for instance, using `npm rebuild` or `npm install`).```


Thank you very much however for all your help and patience.

@RIKKO14 same instructions as post 5 of the topic

[RIKKO14]

everything works except the PIR.
thanks again for your help.
now i need to customize the CSS because my display is so big .

[sdetweil]

@RIKKO14 u used the electron rebuild instructions in the PIR module folder??

[RIKKO14]

sorry I don’t understand your question …
I do not know if I used the electron rebuild instructions in the PIR module folder. I preferred to remove the module so as not to have any conflict while I had the answer to my issue on the MMM-PIR forum because of the Node.js version problem
There, I installed MMM-Assistant2Display which I am trying to adjust and for the moment I am encountering problems of use. I tried the PIR function of this module but it does not work, suddenly I wonder if my HC-SR501 would not be defective

[sdetweil]

@RIKKO14 ok, the fix the node versions problem u need use the electron rebuild procedure I posted. it will throw this error long before ever testing the physical sensor.

u said I started over, and reported the same node version conflict.
