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

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.

I do this :

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

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

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 :

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

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

and this one (because i don’t if it it change something) : https://www.cjoint.com/c/JHvrUegIVzT after the command :

pm2 stop 0
pm2 flush 
pm2 start 0

and after only pm2 logs --lines=100
